I’m doing a project on landsat 5 images. I’ve composited the images into 1 raster, and I want to classify the raster with ISODATA Unsupervised Classification. How do I calculate the best number of classes in each group, the sample interval and the best minimum class size? thanks!

  • Hi Yael. Are you trying to create a land cover classification or some other output? – JWallace Feb 8 '13 at 18:17
  • Hi. I want to create a land cover classification. I'm trying to understand how to choose those values because I need to explain why I worked that way... – Yael Feb 9 '13 at 8:08
