As part of its mission to support and serve the GIS community, PASDA has created a series of tutorials designed to assist PASDA users with data, software, and applications available through the site. While some of them are associated with specific GIS software, they are based upon principles and techniques common to most GIS products.

"GIS Basics"
tutorial is a brief introduction to the basic concepts and principles behind Geographic Information Systems. If GIS is new to you, or you're looking for a simple refresher, this tutorial is for you.
