Modelling INSPIRE based data

specifications for NATURE-SDIplus

Co-funded by the Community Programme eContentplusECP-2007-GEO-317007

OBJECTIVE

To contribute to the development of the data specifications regarding the 4 themes covered by NATURE-SDIplus and development of a data model on nature conservation:

Contribute to the testing of the INSPIRE Annex 1 <Protected sites> proposed data specs

Development candidate data specifications for the 3 Annex 3 themes

Theme 17: <Bio-geographical regions>

Theme 18: <Habitats and Biotopes>

Theme 19: <Species distribution>

METHODOLOGY

Development of candidate data specifications for the following INSPIRE Annex 3 themes Theme 17:

<Biogeographical regions>

Theme 18:<Habitats and Biotopes>

Theme 19:<Species distribution>

DATA MODELS: EXAMPLES

12

FROM UML TO GML Transform the UML model into GML application schema

The standard ISO 19118 prescribes conversion rules for the translation from an application schema in UML into a corresponding XML Schema (W3C, 2002).

OGC: another XML format for GI encoding: GML. Conversion rules: need to respect UML, ISO and GML

constructs SHAPECHANGE: a Java-based tool that takes a ISO

19109 application schema from a UML model and translates it into a GML application schema (Interactive Instruments)
