FRAGSTATS: Spatial Pattern Analysis Program for Categorical Maps

This page contains links to other web sites containing information on related software.

Despite the widespread use of landscape metrics in landscape ecology, there are relatively few packaged software programs available that offer a broad array of metrics. Most of the efforts to date have been tailored to meet the needs of specific research objectives and have employed user-generated computer programs to perform the analyses. Such user-generated programs allow for the inclusion of customized analytical methods and easy linkages to other programs such as spatial simulation models, yet generally lack the advanced graphics capabilities of commercially available GIS. Moreover, most of these user-generated programs are limited to a particular hardware environment or are embedded within a larger software package designed to accomplish a specific research objective (e.g., to model fire disturbance regimes). Despite limitations in computer platform or GIS software dependencies, there are a number of software programs like FRAGSTATS that compute landscape metrics. A brief description of those that I am aware of and a link to a web site where more information can be obtained follows.
Patch Analyst
Patch Analyst is an extension to the ArcView GIS system that facilitates the spatial analysis of landscape patches, and modeling of attributes associated with patches. There are 2 versions of the program: (1) the full version, which analyses both polygon and grid data structures. The full edition requires the Spatial Analyst® extension, which is available from ESRI®; and (2) the Vector Edition (VE), which analyses only polygon data. This version works with ArcView shapefiles and grids, and ArcInfo coverages and grids. The extension was designed for the Win95/NT version of ArcView. Essentially, Patch Analyst provides an ArcView user interface to the old version 2.0 FRAGSTATS, as well as separate Avenue-based spatial analysis functions. The extension was designed for the Win95/98/NT version of ArcView 3.2, but should also work under UNIX. The program was developed by Angus Carr, Rob Rempel and Rob Kushneriuk, with assistance from Phil Elkie and Julie Elliott through funding from the Sustainable Forest Mangement Network (NCE), and with support from the Centre for Northern Forest Ecosystem Research. Patch Analyst (Grid) © is not public domain, but may be used free of charge under a license agreement; it can be downloaded from website listed above.
LEAP II is a broad-based program that provides a number of functions, including the quantification of landscape patterns using the old version 2.0  FRAGSTATS software. LEAP II is built for the Windows NT platform and accepts images in a variety of formats, but is designed primarily to accept 8-bit and 16-bit binary input formats for the FRAGSTATS analysis. The program was developed by Frank Schnekenburger through the Forest Landscape Ecology Program in the Ontario Ministry of Natural Resources. LEAP II is public domain software and can be downloaded from the website listed above.
LANDISVIEW is a tool for converting ERDAS gis files into ASCII grids for compatibility with Fragstats. This tool (currently LANDISVIEW Beta 1.0 and a User Guide) is now available free of charge at the link above.
