ISODATA fail Report this article as Inappropriate to us !!!Login to Reply

I have tried using ISODATA to create land cover classifications with Landsat 8.  My parameters are the default parameters, except I want 20-25 classes, and 100 iterations.  For some reason it always outputs one class, even though I specified 20-25.  Also if I change the threshhold to 50%, .5%, or .05% I get the same results.  Why would ISODATA return only one class?  Can anyone give me some general or specific reasons why this might happen? I am using bands 4-7, NDVI, NDWI, and SRTM.  Thanks :)
