What projection do those satellites use? For example, it looks like GOES comes in mercator or polar stereographic. You would specify one of these projections depending on your dataset.

[QUOTE]MariM wrote What projection do those satellites use? For example, it looks like GOES comes in mercator or polar stereographic.

Envi does not understand the parameters of this projection. I can not independently make this projection list of known for Envi. If it helps, I can send a file as an example in this projection. Description projections in paragraph 4.4.3.2 http://www.eumetsat.int/g...ment/pdf_cgms_03.pdf Please help me. Thanks

I believe that others have used the projection type called "General Vert Near Side Persp" in ENVI for these data. I am not familiar with the Normalized Geostationary Projection, but perhaps it is essentially the same thing? Here is some info about the General Vertical Near Side Perspective projection: http://www.progonos.com/f...r/ProjAz/projAz.html - Peg Exelis VIS
