Hello to all imagesmiths! I just acquired a demo copy of ENVI 4.3 for a class I'm taking, and would greatly appreciate any advice on how best to use it for some UMSF applications. I am completely ignorant of imaging software, but this thing seems to have some nice bells & whistles. My license runs out in April, so if there's anything useful I can accomplish with ENVI for the forum during this period please give me some suggestions...thanks!
