I have a land cover map covering an area of 1560 square km. I am interested in landscape fragmentation analysis using Fragstats. But I am confused about input data for the whole study area. I do not have problem on data preparation but problem about whole study area. I am not sure about how can I use whole study area as input data. Could anyone please let me clear about how can I use my whole study area for the analysis?
ArcGIS 10.2 is your problem. According to the Fragstats information page, you cannot use Fragstats with ArcGIS newer than 10.0:
Version 4.2 should be compatible with all versions of ArcGIS 10.0 and earlier, but it will not work with ArcGIS 10.1 or later.
