This page is an abbreviated listing of the most-used and most-applicable GIS and GIS-related software tools available to our UC San Diego community in the Data & GIS Lab or available for purchase through ACS.
ArcGIS Desktop is the main GIS software we use in the Data & GIS Lab, and this product comes in three different functionality levels: ArcView, ArcEditor, and ArcInfo. The main difference between the three is in the analysis tools offered in ArcToolbox. ArcEditor has more tools than ArcView, and ArcInfo has more tools than ArcEditor. Thus, one builds upon the other. For more details on the differences, simply search do a search online for 'ESRI ArcGIS Desktop Functionality Matrix' and then choose the most appropriate result.
ArcGIS Desktop, at the ArcInfo functionality level, is available on workstations in the Data & GIS Lab. ArcGIS Desktop is also available at assorted locations across campus - see the ACS Lab Explorer for exact and current installation locations.
If you need a free viewer for ArcGIS data, ArcReader is free and downloadable from ESRI and can be used to view GIS data and maps created in ArcGIS without having to purchase the ArcGIS software.
What you, as a current UC San Diego community member, get for free from ESRI!
Interested in getting an ESRI product on your own computer? ESRI products run on the Windows, Unix, Linux and Solaris platforms as well as the new Macintosh Bootcamp platform. All purchases, licensing and distribution of ESRI software is managed by Academic Computing Services (ACS).
Google Earth PRO is available on workstations in the Data & GIS Lab. User-friendly and fun, PRO serves as a visually exciting tool to display and present data in 3D using imagery and terrain data. With PRO you can make a movie of your animation, import GIS data for presentation, and import spreadsheet data such as latitude/longitude coordinates, addresses, or GPS points.
If you are faculty, staff, or a graduate student using PRO in the classroom, you may be able to obtain your own license for Google Earth PRO. In order to obtain a one-year free subscription to PRO for installation on your own computer, the software must be integrated into your curriculum. Check out the requirements and application details (PDF).

Online mapping may be what you need rather than a full-blown GIS. Here are a few top sites for online mapping that are easy to use and relevant to many of the UC San Diego disciplines.
I'm happy to provide additional information on our resources and services.
Please let me know about your questions, comments, and suggestions for this website and for GIS on the UC San Diego campus.
