This tutorial will show you how to use interactive Internet based maps. After this tutorial you should be able to use Geographic Data Viewer successfully; even if you have no prior knowledge of GIS. The basic tutorial will probably take about fifteen minutes. However, in less than five minutes you can have the background required to successfully navigate a Geographic Data Viewer map.

First, we'll cover two basic GIS concepts you need to know. Then we'll introduce you to the tools and methods that you'll use to navigate around the map and ask it questions.

Let's get started.

There are two viewers available to look at maps using over the Internet. Don't worry if this means nothing to you. 95% of Geographic Data Viewer sites use the simple HTML Viewer, so chances are you should press the blue button. If you think your site uses the more advanced Java Viewer, press the red button.
