Abstract

Researchers’ fame in most scientific fields is closely linked to their publishingcapacity, both in terms of quantity and quality. In GIScience, as in other fields, thissituation demands that the researcher evaluate and to be very familiar with thescientific journals in which they could publish. Some specialized journals (e.g. Journalof Citation Reports or JCR) are devoted to ranking these reviews according to variousmethods and criteria. Compared to other scientific communities, GIScience isrelatively new and constantly evolving. Therefore, the journals of this field do notbenefit from any real formal ranking yet. The objective of this paper is to presentthe process and results of a study aimed at addressing this gap. More specifically,the challenge is to elaborate an importance ranking of the scientific journals in thefield of GIScience. To do so, both a qualitative (Delphi study carried out with 40international experts) and a quantitative (JCR impact factor) approach has beenimplemented. This triangulation method leads to an early global ranking of thejournals of this field.

1 Introduction

Researchers’ reputation in most scientific fields is closely linked to their publishingcapacity (Hamilton and Ives 1980, Latour 1987, Hardgrave and Walstrom 1997). Their

production is an important evaluation criterion during the “tenure track” period, aswell as for potential promotions. This production is evaluated not only on the quantityof their published works (for instance, the number of papers published per year), butalso on their quality (awards for the best papers, personal invitation to publish, etc.), aswell as on the way these publications impact their area of expertise (particularly thefrequency with which articles are quoted) (Dubois and Reeb 2000). This

modus operandi

also implies an evaluation of the scientific journals in which researchers publish theirresults. Consequently, in both applied science and humanities, these journals are beingclassified according to various criteria, based on various methods. Specialized journalsare dedicated to this task, such as the Journal of Citation Reports (JCR), which is oneof the most respected by the international scientific community.

Numerous research studies have tackled these issues of evaluating and rankingscientific journals (Garfield 1972, Hamilton and Ives 1980, Tijssen and Van Raan 1990,Gillensen and Stutz 1991, Hardgrave and Walstrom 1997, Moed et al. 1998, Duboisand Reeb 2000, Rousseau 2002). These works have facilitated the evaluation of thespecific contribution of each journal regarding the dissemination of research resultswithin the scientific community, as well as the structuring of communities of practice.

It is now clear that the issue of evaluating and ranking scientific journals is animportant one. Yet, in some relatively new fields, this type of ranking is still quiteinformal. This is particularly the case in GIScience. As far as it is known, journalsrelated to GIScience have not been subject to any formal evaluation. No overall evaluationexists enabling prioritization of the scientific journals in which researchers from ourcommunity publish their works. These journals, however, do not have the same impacton the dynamic of this specific field, and on the transfer of knowledge between GIScientists.Some studies have been carried out in the related field of geography, the most notableof which are Gatrell and Smith (1984) and Lee and Evans (1984, 1985). These studiesare interesting as some of the journals already ranked in the 1980s are still respected byresearchers in GIScience (

Annals of the Association of American Geographers

,

Environmentand Planning A

,

Environment and Planning B

, for instance).Without venturing into any epistemological analysis of GIScience, we assume that

there is

de facto

a community of specialists and scientists who do care about the issuesrelated to the formalization, analysis and use of geographical concepts and data (e.g.University Consortium for Geographic Information Science (UCGIS), Association ofGeographic Information Laboratories for Europe (AGILE)). The GIScience communityhas been developing for more than a decade (Goodchild 1992, Hendriks 1998, Ottens1999, Caron 2000, Fryrear et al. 2001, Murayama 2001, Gatrell 2003). According toBruno Latour’s (1987) analysis, GIScience as described in Goodchild et al. (1999) ismore and more considered to be a special field. Therefore, on the basis of this veryactive community, we wish to identify, then evaluate and rank the journals consideredas being related to GIScience by the practitioners of the field.

Evaluating the specialized journals in GIScience is highly relevant because it willgive a clearer picture of how papers contribute to the advancement of knowledge(Gatrell and Smith 1984). This evaluation will also identify trends that lead to thedevelopment of research policies (Wilson 1985), and that characterize the scientificcommunity (identification of the sub-domains, possible differentiation of the researchers’behaviors according to their type and age, etc.) (Lanegran 1992). The improvement ofthe comprehensive knowledge about the GIScience literature also offers to juniorresearchers, early in their careers, the possibility to identify which journals are the most

relevant to publish in. Furthermore, depending on their publishing strategy, this knowledgeallows them to target selective and prestigious journals or ones that are not too demanding(Hamilton and Ives 1980, Dubois and Reeb 2000).

It is with a view to improving the knowledge of the GIScience-specialized literaturethat we have carried out this study. The objective is to offer a preliminary formalranking of the scientific journals in GIScience. To do so, we chose a methodologicalapproach focusing on both quality and quantity. First of all, a Delphi study

1

, qualitativeand consensual by nature, was carried out on nearly 40 international experts of thefield. Then, the results obtained were consolidated, using triangulation and comparison,with quantitative approaches (particularly the JRC impact factor).

First we develop a contextual framework by providing an update on the majorscientific journal ranking schemes. Then, we explain the methodological approach, andmore particularly the implementation parameters of the Delphi study. Finally, wepresent the results and the consequent ranking. We conclude with the limits andperspectives of this research.

2 Research Conceptual Framework

2.1 GIScience in Action

Before building up a ranking system of the GIScience journals, it is necessary to identifyall the journals in this area. Therefore, a major precondition is to define the currentboundaries of GIScience. Yet, this is a very difficult task since, reciprocally, the decisionof considering whether or not each journal is a part of GIScience and contributes to thevery definition of the field. Bruno Latour’s works offer in this context an interestingframework (Latour 1987). He believes that publications and journals fully participatein the actors’ network, on which scientific fields develop. Consequently, whatever thedifficulty, proposing a reading and understanding grid of this actors’ network meanscontributing to a better understanding and definition of GIScience.

What does GIS mean? GIS tools, systems or science? : This is the type of questionson which the scientific community, involved in geographic information research, hasbeen focusing for over a decade (Chrisman 1999, Pickles 1997, Wright et al. 1997, Mark2000, Schuurman 2000). Our purpose is not to continue this epistemological debate, butrather to emphasize how much this community is alive, how much this new “discipline”or “science” is going through a very rich development period. Whether this dynamismconfers on this discipline the status of science or not is hard to say, but it surely highlightsthe researchers’ strong will to formalize its basic concepts and to define its boundaries.

The last decade has been particularly rich with discussions that fostered theprogressive emergence of a (more or less) shared vision of GIScience. Numerous formsof research, and numerous positions have been proposed since the Spatial DataHandling conference keynotes presented by Michael Goodchild in Zurich, July 1990,and then in Brussels, April 1991, during the EGIS – European GIS conference (Schuurman1999). In 1991, Jean-Paul Cheylan also developed the GIScience concept in an editorialof the

Revue internationale de géomatique

(previously

Sciences de l’informationgéographique et de l’analyse spatiale

). In Canada, the 1980s and the 1990s marked theconceptualization of the field of geomatics (Paradis 1981), and many other publicationsfollowed (e.g. Gagnon and Coleman 1990, Gagnon and Bédard 1994). In 1993, the

Office de la langue française du Québec

(Canada) defined geomatics as the:

Discipline dedicated to the management of spatially referenced data, and thusrelies on the scientific concepts and technologies implied in the acquisition,storage, analysis, and distribution of the data (Bergeron 1993).

The first attempts to formalize GIScience plead for their recognition as a fullscientific discipline. This reasoning emerged out of a strong distinction between GIScienceand GIS software, and went even beyond the debate “tools versus system” thatanimated the community at the beginning of the 1990s. Michael Goodchild (1992) gaveno formal definition of GIScience, but he clarified the scope of this field by identifyingits main characteristics. One of the first definitions was proposed by Frank (1992):GIScience addresses the spatial representation of the data allocated to represent a partof the Earth’s surface.

The 1990s provided a wealth of thoughts and debates. The book coordinated byJohn Pickles (1995) is, in this regard, a significant contribution to the reflections onwhich GIScience developed. A few more papers on that subject were published duringthis period (Pickles 1997, Wright et al. 1997). The “critical GIS” stream arose aroundthe same time, and was widely supported by the publications (articles and researchreports) produced through the National Center for Geographic Information Analysis’s(NCGIA’s) Research Initiative 19. The Varenius project, which followed the NCGIA’sinitiatives, began with the publication of a series of papers in the

International Journalof Geographic Information Science

(the “

S

” was then no more for

system

but for

sciences

, as was the case for other journals that were renamed as the GIScience conceptemerged). In the introduction of the Varenius project, Goodchild et al. (1999) devoteda large part of their article to marking the boundaries of GIScience, to define, but alsoto justify their relevance to scientific, societal and technological influences.

GIScience deals with the fundamental issues resulting from the creation, processing,storing, representation, distribution and use of geographical information. That is to say,and as Goodchild et al. (1999) also specified it, the terms geomatics, geoinformatics,spatial information sciences can be considered as synonymous. A recent definitionposted on the Geographic Information Science Center at the University of California-Berkeley website (see http://www.gisc.berkeley.edu/about/whatisgis.html for additionaldetails) supports this statement:

GIScience has recently emerged as the field where problems of data capture,encoding, storage, analysis, retrieval, synthesis, and dissemination of geographicinformation are studied. These problems have increased in significance as newcomputer-based technologies such as geographic information systems (GIS),digital remote sensing (RS) and Global Positioning Systems (GPS) evolve.GIScience is the foundation upon which these GI technologies are built.

Inspired by the above, we marked the boundaries of GIScience as they have developedfor the last two decades, and as they are considered today. We decided to adopt thisformal and operational definition of GIScience through all the current study. On thisbasis, we constituted the initial corpus of journals for the Delphi study (section 3).

The previous timeline briefly emphasizes the dynamics of GIScience developmentand underlines the significant role of publications and journals in the formalization ofthis scientific discipline. They are crucial in communicating ideas within communities ofscientists, because of the concepts and ideas they explicitly formalize through theirnames (which often change as the discipline evolves), and finally because of the way they

are recognized. GIScience emerged and developed mainly in and through communicationsbetween scientists, more formally through publications and journals.

Apart from any formal ranking, all GIScience journals do not count equally. Thereare differences, especially between peer reviewed journals (such as

Transaction in GIS

)and non-reviewed journals (such as

GIM Magazine

). Among peer reviewed journals,some score significantly higher than other ones. This is the reason why the GISciencejournal evaluation and ranking methodology chosen here is so important, not only forthe development of this still relatively new field, but also as an active component ofGIScience in action.

2.2 Journal Ranking Methodologies

The ranking approach elaborated here required the development of a conceptual frame-work, built on the basis of an analysis carried out to identify the main priority-rankingmethods for scientific journals. The criteria being used are variable: some are quantitative,some are qualitative; some rely on statistical or bibliometric methods, or on qualitativeevaluation processes. Singleton (1976), in his work dealing with the ranking of physicalsciences journals, proposed bringing all of these methods together into three majorapproaches: the analysis of journal article citations; scientists’ assessment of journals intheir field of study; and the evaluation of the size or productivity of the journals.

The first approach adopts the analytical techniques dedicated to the citationspublished in journal articles. The “impact factor” of the Journal of Citations Report(JCR) is surely the most common quantitative evaluation process for citations (Rousseau2002). This approach made clear the fact that the quality of scientific journals is linkedto the impact factor, a term created and used for the first time in 1963 by EugeneGarfield, founder of the

Science Citation Index

at the beginning of the 1960s. Amin andMabe (2000) underlined that the value of the impact factor is directly affected by theresearch field at stake, the type and size of the journal, and may fluctuate over time forsome journals (Gillenson and Stutz 1991). Amin and Mabe (2000) also mentioned thatthe “impact factor” is not only a means to describe the impact of journals on the scientificliterature of a specific field, but it is a strong measurement process for the ranking ofscientific journals, yet this type of indicator should only be used independently for eachdiscipline. Some secondary journals in one specific field may be primary journals inanother field. This type of approach was developed by Gatrell and Smith (1984) toassess the relationships between 22 geography journals. In this study, the authorscalculated how many times journal articles were cited by other journals.

The second methodological approach relies on the researchers’ judgement andappraisal (often qualitative) of journals in their own field. It may have to do with the“freshness” or mean elapsed time between the submission of an article and its publication,or with the calibre and recognition of the members appointed to the peer reviewers oran editorial review board. It may also be related to the review process itself (anonymousor not), or with the calibre of the journal. Hamilton and Ives (1980), Gillenson andStutz (1991) and Walstrom et al. (1995) focused on assigning a rating to various journalswith the help of a numerical scale. For instance, Hamilton and Ives (1980) askedexperts in information system management to systematically score the relative importanceof journals in related fields. Their results revealed that the experts’ perception isvery important. Katerattanakul et al. (2003) went even further, asking academics togive their opinion about the relative value of computer science journals via a series of

questionnaires. Formal techniques have also been developed to assess researchers’perceptions towards journals in their field of study, for instance: Koong and Weistroffer(1989) in management information systems (MIS) and Dubois and Reeb (2000) in inter-national business. Following this approach, Sutter and Kocher (2001) measured, over10 years, the fluctuating recognition of economics journals so as to establish an overallranking through time.

The third methodological approach relies on the quantitative evaluation of the sizeor productivity of journals. Many indicators are used: number of readers, number ofarticles submitted, number of articles accepted, number of issues sold (or delivered),diversity of the subject fields covered, etc. For instance, Todorov and Glaenzel (1990)developed a journal ranking method on the basis of computerized bibliometrictechniques. The journals were organized by speciality areas, relying on the measures ofdispersion (or of concentration) of the subjects treated. Closer to our own field, Lee andEvans (1984, 1985) used this approach to rank 34 geography journals according to thenumber of issues delivered. In this regard, Lanegran (1992) mentioned that

“The growthin the number and circulation of geographical journals has led to speculation about theirprestige and impact

”.So, in many disciplines, studies have been carried out to establish scientific journal

operational rankings. In disciplines closely related to GIScience, issues relating to journalranking have also been tackled. For instance, Brancheau et al. (1996) determined thecritical issues with regard to information systems. Sabrin (2002) developed a classificationof the academic institutions offering information systems training in the United States.Walstrom et al. (1995) dealt with the ranking of information systems conferences. Yet,nothing of the kind formally exists in GIScience.

Granting agencies, or research institutions themselves have a true interest in possessingsuch a ranking system, since publications still constitute today one of the major criteriato evaluate researchers (obtaining grants, tenure and promotion, etc.). For instance, theFrench

Centre National de la Recherche Scientifique

(CNRS) launched in 2004 anaction to assess the place and influence of French journals dedicated to human andsocial sciences at the international level. An inquiry based on the impact factor principlewas then started. Finally, 18 disciplines were chosen, and the journals were analysedbetween 1992 and 2001. This analysis ranked 125 journals in three categories: (A) veryhighly rated international journals, (B) highly rated international journals and (C)national audience journals. This ranking is now a basis for the evaluation of researchersand French laboratories.

3 Description of Methodological Approaches

We believe that an intersectional approach could strengthen the ultimate outcome;consequently we have opted for a methodology integrating the first and second approach.The first step is mainly based on the Delphi method (Loo 2002). The rationale forchoosing this qualitative and consensual method was two-fold: the appropriateness ofbeing directly in contact with the researchers in a still young and developing field;and the lack of quantitative data relating to GIScience journals (with particularly fewjournals mentioned in the JCR). This step allowed us to generate a consensus as well asan initial ranking of GIScience journals, so as to better interpret the results obtainedwith the Delphi.

3.1 The Delphi Method

The Delphi method has been the subject of many studies in various fields: health(Demeyrick 2003), information systems (Brancheau et al. 1996, Schmidt et al. 2001),banking (Bradley and Stewart 2003), and marketing (Mitchell and McGoldrick 1994).Yet, in GIScience, this method of investigation has not been used extensively (Roche etal. 2003, Péribois et al. 2005). Consequently, before going further, it is useful to reviewsome of the elements relating to this approach. There are several variants (Linstone andTuroff 1975, Mitchell and McGoldrick 1994, Brancheau et al. 1996). We have chosenLoo’s method (2002), which appears to be the more straight forward one. Loo (2002)identifies four major steps: (1) define the problem; (2) select the participants; (3) determinethe size of the sample; and (4) conduct the iterative surveys of the Delphi method.

Kaynak and Macaulay (1984) underscored the fact that the Delphi method is usedin response to a situation or a phenomenon rather than to test hypotheses. That is tosay, the Delphi method is efficient at explaining a problem or defining a situation, ratherthan assessing the relationships between hypotheses. Therefore, we consider that it iswell adapted to develop a GIScience journal ranking methodology.

General approach.

Successive questionnaires are sent to a targeted group of expertson a given theme, until a consensus on the questions posed is reached. This method isused to establish a consensus of opinion on a more or less quantitative specific subject.It allows the researchers to predict, develop and explore the attitudes of a group, as wellas their needs and priorities (Jairath and Weinstein 1994). Iterations allow for feedbackfrom one survey to the other. Usually, three iterative surveys are enough to complete thestudy (Duffield 1988).

Jury.

The Delphi study is directed by a small group of jurors. The members of thejury are not chosen at random but selected according to their subject matter knowledge(Deitz 1987).

Expert.

The definition, the choice and the maintenance of anonymity of the expertsare the key elements of a Delphi study. They prevent personal opinions from leadingthe study. Moreover, anonymity stimulates ideas, as well as observations without anypressure of external factors or from pairs (Goodman 1987).

Group of experts.

The constitution of the group of experts is critical to the rigor ofthe Delphi study (Linstone and Turoff 1975). The chosen respondents must be repre-sentative of the group and be familiar with the discipline or issue. The constitution ofthe group of experts in the present study is mainly based on Martino’s (1983) theories.In some specific fields, experts are too few in number to be chosen randomly. There isno formal rule regarding the size of a group of experts (Linstone and Turoff 1975, Loo2002). Martino (1983) proposes a rule of thumb: a group of 15 to 30 experts is necessaryfor a heterogeneous population, where a group of 5 to 10 experts is enough for ahomogeneous population. To test a medicine, a heterogeneous population will consistof physicians in an academic health-science centre, whereas a homogeneous populationwill consist of specialist physicians in cardiology, for instance.

Limitations/Sources of error.

The Delphi method does not escape criticism. Sackman(1975), and then Woudenberg (1991), raised a series of questions about the scientificbases of the Delphi method, whereas ample scientific evidence clearly demonstrates itsusefulness. Linstone and Turoff (1975), Martino (1983), and Loo (1997, 2002) confirmedthe good performance of the Delphi technique, but also specified the precise criteria thatare required to ensure efficiency and exactness. Constituting the group of experts and

determining the sample size are particularly important criteria. Choosing experts formdifferent geographical locations, or confirming the experts’ reputation through informaldiscussions is also essential. Based on successful research outcomes, Mitchell andMcGoldrick (1994), Blow and Sprenkle (2001) and Bradley and Stewart (2003) allagree. In order to mitigate the limits of the Delphi method, Dootson (1995) suggestedadopting a triangulation approach, using other complementary methods as well, whichis adopted in the present study.

The sampling of experts.

The sampling process of experts is non-probabilistic innature, since the individuals are not chosen randomly. Sacks (2000) mentioned that themore qualitative studies typically imply small samples, and enhance the sample repre-sentativeness rather than its size. We used Martino’s (1983) guidelines to gather ahomogeneous group.

In this study, the experts were chosen from a thorough study of the peer-reviewjournals in the fields of geomatics, geography, geographical information systems, andother related disciplines. We listed all the Internet sites of these scientific journals so asto identify the members of their respective editorial boards. This identification tookplace over a period of several weeks. Based on an initial population of 1,110 expertsreported in the editorial review boards, a first sample of 174 experts was drawn. Thisfilter was carried out according to the following criteria: experts serving on at least twoeditorial review boards and with an expertise in GIScience. The group includes selectedexperts from all over the globe.

3.2 Constitution of the Initial Corpus of GIScience Journals

First, an initial listing of GIScience journals was compiled. The sampling process, usedto generate this basic corpus from the Delphi study, is non-probabilistic since the jour-nals were not chosen at random. More specifically, we have mainly used the followinginformation sources:

• Journal of Citation Reports 2003 – Social Sciences Edition, Institute for ScientificInformation (ISI), Thomson Scientific, Philadelphia, microfiches.

• A selection of journals from the lists of the following sources : http://www.crg.ulaval.ca/revues/revues.asp (June 2002), http://www.geomatique.georezo.net (June 2002), andhttp://www.forum-pggq.com/liens/index.asp?section=10 (June 2002).

• Research guide 2002–2003, Business Administration Department, Université deSherbrooke.

• Taylor and Francis Journals: http://www.tandf.co.uk/journals/sublist.asp• Blackwell Journals: http://www.blackwellpublishing.com/listofj.asp• Elsevier Journals: http://www.elsevier.com/wps/find/journal_browse.cws_home• Biblio-GIS – Journals: http://perso.wanadoo.fr/dupuy.allignet/bibliosig/revues.htm

An initial sorting, produced by the jury

2

, reduced the corpus of 121 journals identifiedat the beginning in the sources mentioned above, to 84 journals. After the first iteration ofthe Delphi study, scientific journals that were region-based or unknown to most expertswere removed, as well as those published in languages unfamiliar to the experts, or thosewhose content was not relevant to the definition of GIScience adopted in this study.

After the experts’ suggestions and the jury deliberation, the list of scientific journals,used from the second iteration of the Delphi study with regard to the classification,consisted of 54 titles

. Among these 54 journals, some are Francophone, but the vast

majority is Anglophone, i.e. most of them come from North America and WesternEurope.

3.3 Comparison with Other Measurement Approaches

To validate the classification resulting from the Delphi, we have compared it with theJCR impact factor. Only some of the journals listed in the Delphi appear in the JCR,which limits the comparison to only some of the classified journals. The ISI

(

Institutefor Scientific Information) JCR multidisciplinary database offers statistical data used toassess how significant publications are in various fields. Two versions are available:

JCR Web Science Edition

: 5,000 leading international scientific journals•

JCR Web Social Sciences Edition

: 1,600 key international journals

The impact factor is a quantitative measure of the frequency with which the articlesin a particular journal of a given field have been cited, compared to the other journalsof the same field. The impact factor is defined as follows:

The average numbers of times recent articles in a specific journal were cited inthe JCR cover year. For JCR impact factors recent articles and those publishedin the two years preceding the JCR cover year. There are other ways ofcalculating journal impact (Garfield 1972).

The impact factor is calculated by dividing the total number of citations publishedduring the previous two years by the total number of articles published in those twoyears. For example, the impact factor of the

American Political Science Review

is 2.448,resulting from the following calculation:

– Number of citations in 2002: 123– Number of citations in 2001: 152– Number of articles published in 2001: 50– Number of articles published in 2000: 46– (123 + 152)/(50 + 46) = 235/96 = 2.448

The comparative approach used here consists of determining whether the sortingin descending order of importance resulting from the Delphi also corresponds to adescending impact factor.

4 Methodology Used in This Study

4.1 Questionnaires

A questionnaire was developed for each round of the Delphi (Appendices 1–4), and wasthen distributed iteratively to the experts. The questionnaire was produced in English

.To ensure a good understanding of the questionnaire, pre-tests were conducted beforeeach iteration on the jury of the Delphi and researchers from the GeoBusiness Group(Université de Sherbrooke) and the Center for Research in Geomatics (Laval University).Furthermore, a definition of “GIScience” was included with the questionnaire, in orderto make clear the boundaries of this particular field. To facilitate the experts’ work, thequestionnaires were developed using a four-level classification of journals (Facultéd’administration 2002):

– Level 1: journals ranking in the top 15% of their field– Level 2: journals ranking between 16% and 50% of their field– Level 3: journals ranking between 51% and 100% of their field– Level 4: journals that are not part of the first three categories

When an expert had difficulties classifying some of the journals in one of the fourcategories, this person could indicate “unknown” rather than a number from 1 to 4(Hufnagel and Conca 1994).

An identical analytical method was used between each survey. The jury studied theresults and made certain decisions, such as discarding some redundant journals, andthen developed a questionnaire for the next survey. Each questionnaire listed the jour-nals in alphabetical order to prevent the experts from being influenced by a presentationof the journals in descending order (which may have led them to concentrate on theevaluation of each journal individually).

4.2 First and Second Rounds

In August 2003, we sent an e-mail to the 174 experts of the original group. Thesee-mails included a customized introductory letter, as well as the first questionnaire(Appendix 1). A first reminder was sent three weeks after the initial message, but onlyto 140 experts, for some e-mail addresses were invalid and certain experts had alreadyaccepted or refused to participate in the study. Most of the refusals were on the groundof lack of time, or because some of those contacted were deemed insufficiently qualifiedwith regards to GIScience. Thirty-seven experts (21%) answered the first round.

With the first questionnaire, the experts’ mandate was two-fold: to comment on therelevance of each of the 84 journals appearing on the list, and to suggest adding missingjournals (Appendix 1). The following choices were offered: to decide whether a journalshould remain or be removed from the list for the second round, or to make no com-ment if the expert believed they did not have the necessary knowledge to judge thejournals or to include additional journals. At the end of the first round, the experts’suggestions and comments enabled the jury to correct and enrich the original list.

Twenty-eight additional journals were proposed by the experts during the firstround (Table 1). Once the analysis and screening (number of experts who suggested ajournal, relevance of the journal regarding GIScience and breadth of the journal), thesix following journals were added by the jury:

Cybergeo

,

Directions Magazine

,

GIMInternational

,

ISPRS Highlights

,

Marine Geodesy

and

The Professional Geographer

.Moreover, updates were proposed, because some journals had changed their names

in recent years. It is the case for the

Journal of the North American CartographicInformation Society

, known today as

Cartographic Perspectives

, but also

MappingAwareness

that is now

GI News,

or even the

Revue de géographie de Lyon

which todayis named the

Géocarrefour

. Some experts also emphasized certain redundancies –the same journal was listed twice, but under two different names:

Cartography andGeographic Information Systems

(same as

Cartography and Geographic InformationScience

),

Geographical Systems

(same as

Journal of Geographical Systems

).The second round took place from November 2003 through January 2004. Its

process was the same as the first one, both in terms of questionnaire and outcomemeasures. It included two reminders over a period of a month. Out of the 37 expertscontacted during the second round, only 28 answered the second questionnaire

(Appendix 2). This questionnaire required the experts to proceed in the same way as forthe first round, but then, they also had to propose a first classification for each journal.To conclude this second round, the jury had once more, and using the same method, todecide about the new journals added, as well as about the journals that the experts couldnot make up their mind, whether they should remain on the list or not.

4.3 Third and Fourth Rounds

The third and fourth rounds took place, respectively from February 2004 to March2004, and from April 2004 to May 2004. Both rounds followed the same patterns andincluded two reminders over a period of a month. The questionnaires distributed to theexperts during both rounds are very similar (see the questionnaire of the third round,Appendix 3). Both iterations have the same goal, namely to request each expert to

classify each journal according to the categories ranging from 1 to 4. Unlike the firsttwo rounds, these last two were no longer offering the possibility to add or removejournals from the list. Each expert had two pieces of key information at their disposalto proceed to a classification, that is to say: (1) their own evaluation of each journalduring the previous round and (2) the group of experts’ average rating of each journal.The fact that each expert could have access to the average rating given by the grouprepresented an opportunity to be influenced. The expert could then maintain his/herevaluation for each journal, or follow the overall opinion, so that a group consensuscould be achieved progressively and anonymously.

In fact, 27 experts answered the third iteration, whereas at the end of the fourthand last iteration they were down to 26, which corresponds to a net response rate of14.9% (26/174). This rate is very good and in line with expectations, since the literatureforecasts a 15% response rate for Delphi studies (Linstone and Turoff 1975). Theerosion of the group of experts after each round is a consistent characteristic of Delphistudies, the average desertion rate usually reaching 10% to 40% (32% in our study).The distribution of experts by country at the beginning and end of the study issummarized in Table 2. The large majority came from Northern America (50%) andWestern Europe (27%).

The various iterations of a Delphi are complete only when a final consensus isreached. Therefore, for the third and fourth rounds, the jury had to decide whether theiterations should stop or continue. With regard to our study, four rounds were carriedout, which is in line with the development standards achieved by a Delphi study, whichusually consists of three to six rounds (Bradley and Stewart 2003, Linstone and Turoff1975).

In order to determine accurately the achievement of a consensus, the jury measuredthe stability factor (Scheibe et al. 1975) during the third and fourth rounds. For a giveniteration, the stability factor is the ratio between the total of units changed (in this case the

differences between the answers given for each journal in two successive questionnaires),and the number of participants (the total number of experts in a given iteration). Thiscalculation gives a percentage change, which should remain below 15% to have theconsensus achieved.

Table 3 shows the classification obtained at the end of the fourth iteration of theDelphi. This ranking reveals a consensus among the experts contacted (for comprehensiveresults, see Appendix 4).

5 Analysis and Triangulation of Results

Once the final results of the Delphi were obtained, we proceeded with the second partof the study, namely the comparison with the JCR impact factor. To do so, we produceda table comparing all the journals of the Delphi, ranking them from 1 to 3 that werementioned in the JCR (Table 4).

Table 4 indicates the JCR Rank in its main field for each journal analysed, whichenables the calculation of the ranking percentage for each of those journals. Forinstance, the Applied Geography journal ranks 25th among the 35 journals listed in thefield “Geography”, that is to say 71st out of 100. Within a categorization ranking from1 to 4, a ranking of 71% based on the JCR data corresponds to a level 3. Out the 44journals ultimately classified from the Delphi, the same journal ranks 34th, which alsocorresponds to a level 3. It is, thus, easy to make comparisons between the Delphi andJCR approaches.

We have been able to compare nearly 50% of the journals from the Delphi (21/44).Based on the analysis of these 21 journals, we can say that for:

57%: both classifications coincide43%: both classifications do not coincide, but out of these 43%:20%: the ranking resulting from the Delphi is just above the one calculated from

the JCR;23%: the ranking resulting from the Delphi is just below the one calculated from

the JCR.

Consequently we can conclude that there is a match between the classificationresulting from the Delphi and the one compiled from the JCR (57%). When there is no match(43%), the ranking given by the Delphi is equally just above or below the one resultingfrom the JCR. On that account, the triangulation of the Delphi results and the JCR dataconfirms the classification obtained. Therefore, we believe that, in regard to the 44 journalsthe international experts consensually classified, the Delphi constitutes an innovativeand sound methodology to determine the importance of the journals in GIScience.

The final ranking, built on the basis of the Delphi and confirmed through a trian-gulation with the JCR, is presented in Table 5.

6 Conclusions

The classification, developed in a rigorous qualitative manner (Delphi method), has beencorroborated by a quantitative approach (JCR). Consequently, the resulting overallranking helps to correct a deficiency in GIScience.

Indeed, there are limits to these results. First of all, the group of experts contactedis over-represented by residents from North America and Western Europe. Generalizationto the whole international community is, thus, precarious. For instance, how relevantthese results would be to Asia, especially China? Moreover, we did not carry out ananalysis aimed at determining in detail the experts’ specialized fields of expertise.GIScience is characterized by a large variety of disciplinary backgrounds and expertise.These specializations could, if the case arises, challenge the representativeness of thegroup. For example, what could be the impact on the classification of certain journalsthat are more specialized in photogrammetry or remote sensing? It is difficult to say.

The scale proposed here to carry out the Delphi (ranks from 1 to 4) entaileddifficulties in the experts’ decision-making process regarding the evaluation of somescientific journals. For instance, some of them gave half scores, such as 2.5 or 3.5. Then,we had to contact the experts to ask them to make a choice. Other experts informed usthat they had difficulties to carry out the exercise, mainly due to the very limited ratingscale. The rating exercise may have been easier if the experts had a wider choice thanthe initial ranking from 1 to 4. For example, how might a five or seven-point Likertscale have impacted the results?

Finally, the list of scientific journals covered by the Delphi does not pretend to beexhaustive, even though it was compiled on the basis of various sources of information,as well as on suggestions made by the participating experts. It is clear that the methodused to develop this ranking will have to evolve with time and according to the experts’commentaries and further inquiries.

Sometimes though, this classification will necessitate updates. Journals evolve andtheir rankings change over time as well, GIScience will evolve too, just like disciplinescontinually do. The constant redefinition and the steady integration of new conceptsand new information technologies (IT) imply the need to maintain and improve ourglobal knowledge in this field. In order to make guarantees about how current, andthus, useful this classification is, it is important to keep on improving and enhancingthis first version.

Generally speaking, it would be interesting to transpose this type of exercise toconference rankings in GIScience (e.g. COSIT, GIScience conference), with respect tothematic content and prestige, for example. Furthermore, we are convinced that themethodology of this work could be generalized to research fields other than GIScience.The Delphi method appears to be an innovative and efficient way to achieve this purpose.

We consider the innovative approach used in the present study as complementaryto the JCR approach. It efficiently fills some of the gaps of the JCR, such as the lack ofconsideration for some key journals, and because few other rankings of journals fromthe emerging field of GIScience have been attempted. This complementarity might implysome changes relating to the criteria used to constitute the JCR, i.e. to complete thesecriteria with others based on consensus building, such as the Delphi method.

Moreover, since the approach used in the present study aims at reaching consensusamong subject-field experts, we consider it as a sensible means for publishers, people incharge of tenure-track and promotion decisions, and granting agencies to evaluate thecontribution and reputation of journals. We do hope that the present research will leadto the development of a new journal ranking approach in the field of GIScience, andpossibly in other research fields. In this regard, we are ready to get involved in anyinitiative aiming at structuring some kind of process to periodically update the resultsof the present study.

Notes

1 The method for structuring a group communication process so that the process is effective inallowing a group of individuals, as a whole, to deal with a complex problem confidentially(Linstone and Turoff 1975).

2 The jury of the Delphi study consists of the authors of this paper.3 One mistake was made during the Delphi study. The title: “Geographical Information Systems

for Urban and Regional Planning” was part of the final list compiling the 54 journals, eventhough it is not a journal but a book. One of the experts had suggested adding this title duringthe first iteration of the Delphi. But, neither the experts nor the jury of the Delphi ever detectedthis mistake afterwards. Yet, it hardly affected the final ranking. We ultimately removed thistitle. This mistake does not invalidate the remainder of the classification obtained.

4 A French version of the questionnaire was available upon request.5 The fourth level corresponds to journals without editorial boards, that is to say professional

or transfer journals.

Appendix 2: Questionnaire #2

Dear Sir/Madam,

We are pleased to note that you are among the 38 experts that answered our first surveyconcerning our research project for classifying the scientific journals in the field ofGeographic Information Science (GIS). For a second time, we request your professionnalskills to complete Survey # 2.

Following your suggestions from the first round, we eliminated nearly 20 journals.However, we need your opinion, a second time, to evaluate some other journals fromthe first round. Also, some new suggestions of journals provided by some of yourcolleagues who answered the first survey need to be evaluated.

To do so, we provide you a definition of Geographic information science:

“GIScience has recently emerged as the field where problems of data capture,encoding, storage, analysis, retrieval, synthesis, and dissemination of geo-graphic information are studied. These problems have increased in significanceas new computer based technologies such as geographic information systems(GIS), digital remote sensing (RS) and Global Positioning Systems (GPS) evolve.GI Science is the foundation upon which these GI technologies are built.”

(Source: http://www.gisc.berkeley.edu/about/whatisgis.html)

Please, answer the following two questions that represent your opinion.

1) Look at the scientific journals above and indicate those which, according to yourexpertise, do not deserve to be evaluated because they do not belong in the field ofGeographic Information Science. Please answer the question in the column entitled“Yes, No or ?” question. (If you are unfamiliar with the journal, put a questionmark (?))

2) For each journal in both lists, identify its ranking according to the scale below(If you are unfamiliar with the journal, put a question mark (?))

– Level 1: Peer journal classified among the first 15% of their field– Level 2: Peer journal classified between 16% and 50% of their field– Level 3: Peer journal classified between 51% and 100% of their field– Level 4: Journal not part of the first three categories

(For example: A journal that does’t have a referee process.)

Please reply by December 12th, 2003 with the survey completed at:

• Email address: [email protected]• Fax number: (819) 821-7934. (Directed to the attention of Claude Caron)

Appendix 3: Questionnaire #3

Dear Sir/Madam,

We are pleased to note that you are among the experts that answered our second DelphiSurvey concerning our research project for classifying the scientific journals in the fieldof Geographic Information Science (GIS). We are providing you with the results ofSurvey #2 and we require your professionnal skills to complete Survey # 3.

Referring to the definition of Geographic Information Science *, please answer thetwo questions below:

*“GIScience has recently emerged as the field where problems of data capture,encoding, storage, analysis, retrieval, synthesis, and dissemination ofgeographic information are studied. These problems have increased insignificance as new computer based technologies such as geographicinformation systems (GIS), digital remote sensing (RS) and Global PositioningSystems (GPS) evolve. GI Science is the foundation upon which these GItechnologies are built.”
