Hello, i have created combine raster for 4 multi-temporal images and in the attribute able also created final land use field with final values. ( have created this values via "select by attribute" and added different images with final value according phenology). I just know, it is not so easy to create error matrix for final land use raster, but anyway, i dont know which way is good in ArcMap? Is there any appropriate option for this aim? thanks a lot!!
