FRAGSTATS 4.2.0.20171213

FRAGSTATS is a public domain computer software program designed to compute a wide variety of landscape metrics for categorical map patterns.The original software (version 2) was released in the public domain during 1995. The program was completely revamped in 2002 (version 3). Recently, the program was upgraded to accommodate ArcGIS10 (version 3.4). The latest release (version 4) reflects a major revamping of the software, with a completely redesigned architecture intended to support the addition of cell-level metrics and surface pattern metrics. The current release of version 4 (v4.2) has essentially the same functionality as version 3, but with a new user interface that reflects the redesign of the model architecture, support for additional image formats, and a variety of sampling methods for analyzing sub-landscapes.

Package Parameters

If you have a valid ESRI ArcGIS license with Spatial Analyst or ArcView 3.3 Spatial Analyst and intend to work with ArcGrids (or Rasters), you can use a /DLL package parameter to add the necessary folder path of the aigridio.dll library file. This path is not verified.

For example : choco install fragstats -params '"/DLL:""C:\Program Files (x86)\ArcGIS\Desktop10.2\Bin"""'. (note: the double-double quotes around the path are only needed if it contains spaces)
