With the release of such programs as Google Earth, computer users have access to a rather diverse set of geographical data tools. One program that has recently been released in a new edition is the Geographic Resources Analysis Support System (GRASS). With this program, users can perform a number of tasks, such as spatial modeling, visualization, and image processing. The program may be a bit complex at first for some users, but its uses are very diverse. The site also includes a FAQ section and a newsletter. This version is compatible with computers running Windows 98 and newer or Mac OS X and newer.
