I am attempting a GIS tutorial on land change analysis between two rasters. I have set the extent and raster analysis to what I have been given and used the expression below. However, it is not working. Could someone provide some clues as to what I have be doing wrong? I have followed all instructions... I can't see what the error no is.
Con("%lc1991%" == "%lc2001%",0,1)
000539 is the error I get and I had a look and it said cannot concatenate a string and integer. This is the expression I was told to use. Does anyone know how to construct a better expression?
