What data types are supported in Land Change Modeler for ArcGIS?
Grids or Shape files must either be in 4-byte floating point, 2-byte signed integer, and unsigned byte to be used with Land Change Modeler for ArcGIS. You may have to use the Reclassify tool in ArcGIS to change the NoData value in the Grid file so that it is in the range of the data formats above. For example, if you have a land cover map with 11 categories and the NoData value is set to -32767, you will need to Reclassify the NoData value to 255 or 0. The output data type will then be an unsigned byte which can then be used for Change Analysis.
