Introduction to GIS

Web-based maps have many similarities to traditional paper maps, with some important differences. Instead of just looking at the map, you can explore vast amounts of information for a geographic area far-out or close-up, and learn more about specific features, and (most importantly) get answers to your questions.

In case you're wondering how it all works, Geocortex software provides the user experience and interface for your web-based map, while ArcGIS Server, ArcIMS, or other software can provide the mapping engine. Together, they translate complicated GIS technology into a form that can be used by ordinary people around the world to explore geographic information like never before.

This short tutorial will provide you with the knowledge you need to successfully work with Geocortex web-based maps; even if you have no prior knowledge of Geographic Information Systems (GIS).

Once you've read through the introduction, you'll be able to start exploring the Geocortex web-based mapping application. Spend a few minutes reading through the Tools and Tasks section to familiarize yourself with some of the more advanced operations at your fingertips. You'll quickly see how easily these tools can get you answers to some surprisingly sophisticated geographic questions.
