FRAGSTATS is a computer software program designed to work with geospatial data to help the user categorize landscape patterns and metrics, and is useful in identifying areas where land use activities have resulted in fragmentation of the landscape. The current release is version 3.3
The program is currently undergoing another major revamping, which will result in the release of version 4.0 sometime in 2011.
Version 3.3 is a stand-alone program written in Microsoft Visual C++ for use in the Windows Operating environment. It accepts raster images in a variety of formats, including Arc Grid, ASCII, 16 or 32 bit BINARY, ERDAS, and IDRISI image files. However, currently FRAGSTATS does not work with newer versions of ERDAS Imagine files.
