--- Start of Idrisi List message Hello all, I am a new user of Idrisi32. I have some classification problems. What I have are series of Landsat TM images (bands 1-7), land use image, topographic map. What I have to do is produce new land use map base on the Landsat images and compare to the old one. Do you have any advice? For instance: steps to do the classification. Many thanks in advance, Nguyen --- End of Idrisi List message IDRISI-L is an unmoderated list. As a service to list users, please post a summary of useful responses to your questions.
