Hi Jim, You are going to need to go with option 2, as these things you require are not trivial to do. I'm a bit biased toward ER Mapper as I use it and sell it, but it is really powerful software. I promised myself not to work with software that I don't like. ER Mapper has many wizards to help you through various processes. It also has ECW image compression, which is similar to MrSID compression, but has been reviewed in various geomatics magazines as being better. As scanned airphotos can take up a significant amount of hard disk space, I would recommend compressing them after processing them. BTW, MapInfo Pro can display ECW files. I hope this info helps.

I want to end up with a georeferenced, orthorectify, NDVI image that I can import into MapInfo. I already have the sights mapped in MapInfo and I was wondering how others on the list managed this. As I see it I have 2 options: 1.. An add-in (like VM?) 2.. A separate program in which I can process the images and then translate the georeferenced and orthorectify images into MapInfo. I have not found anything like option 1 but in option 2 I have looked at ER Mapper, Idrisi, ENVI , CHIPS and others. Could anyone offer some advice / opinions/ comments please? Thanks again all, Jim Jim Wilson Hilton of Fern, Brechin.
