Hi everyone, I did Land Change Modeler
I can do every step, and I drew landcover predict map, but I cannot do validation, predition map and my map.
Error : more than 256 combinations found.
How can I fix it?

For the validation section of LCM, it does a 3-way crosstabulation between the original land cover image, the predicted land cover image and the validation land cover image.
That error message says that there are more than 256 combinations between the categories in those 3 images. Unfortunately, we currently have that 256 combination limit for CROSSTAB.
If you were to reduce the number of transitions in the analysis, perhaps by increasing the minimum area for the transition (on the Change Analysis page), then you might have less combinations.
I am going to see if there is something we can do to increase the number of combinations allowed, but that is currently the limit.
