Hello Tom: Tom I can successfully read mcidas a McIDAS area file outside of Mcidas. I want to do the following all outside of mcidas: 1) read a goes image 2) have user enter a latitude,longitude 3) then convert that latitude,longitude to a file coordinate. If I have an image already loaded step 3 is easy. I use itvll or is it illtv. Either routine, but it looks to me that if I am running out of mcidas I have no such routine. I will probably have to us mcanav or maybe navinit, etc. I will look at the program "imgremap.k" for my template. Question: Is there a simple routine like "itvll" that will convert latitude,longitude to file or image coordinates and doesn't requiring making all the other calls? Thank you Tom, Sincerely, Craig >From address@hidden Wed Aug 30 15:43:16 2000 I was being lazy when I asked my last question. I will just play with nvset, nvprep, etc. I think that is the way to go! If I get stuck I will get back to you and then ask questions: Thank you, Craig
