Is there an automated way to set up a batch file for use in Fragstats?

The main FRAGSTATS documentation has a section on the necessary format of the batch file, also in the tutorials package there is an entire section on batch processing, so I wouldn't really call it useless.

Each line of the batch file contains the path to the file, and attributes about the raster. Since you are using GeoTIFFs most of these attributes can be read automatically by FRAGSTATS. So really you just need to get a list of your rasters and output the paths to a text file. This becomes a fairly simple task in Python.

import arcpy

from arcpy import env



#Set workspace to folder containing GeoTIFFs

env.workspace = "Q:/Temp/Files"

#List all GeoTIFF datasets in workspace folder

fllst = arcpy.ListRasters("*", "TIF")

#Set the output path for batch file

txt_path = os.path.join(env.workspace, "geotiffbatch.fbt")

#Open batch file for writing

txt_file = open(txt_path, "w")

for fl in fllst:

    #Construct path string to dataset

    pth = os.path.join(env.workspace, fl)

    #Construct string formatted for batch file

    outStr = pth + ", x, 999, x, x, 1, x, IDF_GeoTIFFn"

    #Write string to batch file

    txt_file.write(outStr)



#Close batch file    

txt_file.close()

The batch file is ready to read in FRAGSTATS where you can then setup the metrics and output location. I would recommend looking at the tutorial package linked above for more information.

If the files were Ascii grids or other formats that FRAGSTATS will not automatically read the attributes of you could use arcpy.Describe() to get the raster attributes necessary.

  Thank you very much! As a python illiterate, I still do not know by what to replace the "x" in : outStr = pth + ", x, 999, x, x, 1, x, IDF_GeoTIFFn". Would you know how to have the number of rows an columns written in the text file in place of those "x"?

  This depends on what your raster format is. In this case it is a GeoTIFF which FRAGSTATS will read that information from the header of the file. This is also the case for several other raster formats that can be read by FRAGSTATS. You would only need to change those if you were using an ASCII grid or something similar.
