The Future Is Now!
GIS is more than just software… it’s a system!• More than just for making maps
(although a GIS has tools for making nice maps!)
• Meant for making decisions about place
• Goal: use should be pain free!

Types of GIS
Desktop GIS• Creation, analysis, editing and visualization
Server GIS• Management, archiving, sharing, distribution,
and review Mobile GIS
• Collection and navigation Online/Web GIS
• Directly related to Server GIS

Web GIS
Web mapping is the process of designing, implementing, generating and delivering maps over the Internet
Web GIS• Emphasis on the analysis and processing of project
specific geospatial data Challenges
• Copyright• Security• Reliability• Technical complexity
author: Todd J. Schuble, University of Chicago
Web GIS
GIS in a browser based environment
Not platform or device specific!
author: Todd J. Schuble, University of Chicago
Advantages to Web GIS
No need for GIS Software with the users No need for training the users in GIS Changes made to the map and/or
database repository are reflected everywhere
Authenticity and accuracy are guaranteed by the provider
Small amount of hardware serving multiple users and multiple purposes

All Web Maps Are Not Equal
Static web maps• Any sort of map image (TIF, GIF, JPEG) embedded in a
website Animated web maps
• Behaves as an interactive map via animated GIF, Adobe Illustrator, or some other graphic software
• UChicago.edu campus maps Real-time web maps
• Weather, traffic, earthquakes, etc.• NAVTEQ traffic, Planefinder.net,
USGS Earthquake Hazard Program
author: Todd J. Schuble, University of Chicago
All Web Maps Are Not Equal
Personalized/interactive web maps• User defined styling and data filtering• Umapper, Batchgeo, Google Earth
Analytic web maps• GIS enabled with spatial analysis tools• Social Explorer, PolicyMap, China Data Center
Collaborative web maps (Cloud GIS)• Distributed data acquisition and maintenance• Geocommons, ArcGIS Online,
ArcGIS Business Analyst Online

Collaborate with Users in a Secure Environment
author: Todd J. Schuble, University of Chicago
Collaborate with Users in a Secure Environment
Cloud GIS• Cloud environments typically provide:
Software as a service (SaaS) Platform as a service (PaaS) Infrastructure as a service (IaaS)
PRC GIS Collaboratory• The power of GIS• The security of your own desktop• All through a browser!
