UC Berkeley's Knight Digital Media Center--Maps Tutorials. "This site of tools is designed to help people get started with using maps in their various publications and presentations. The presentations here include "Map Mashup Resources", "Google Map Basics", "Embedding Map Mashups" and "Map Mashups: Collaboration". Each of these presentations includes a video orientation that will help users get started quickly with their own work. A particularly useful resource is the "Embedding Map Mashups" tutorial, which will teach interested parties how to quickly embed their newly created maps into their own sites. The last section of the site is titled "Maps Links and Resources", and here visitors can learn about how maps are being used online to share information and also find a list of "100 Things to Do With Mashups""--as described by the Internet Scout Report.
Geospatial Solutions. A GIS magazine (with additional resource and career information) closely associated with GPS World.
In the library, the Government Documents computer has ArcGIS installed.
