I tried to open an AVHRR NDVI product in ENVI. The orginial file format is ER Mapper (*.ers). When I imported it into ENVI, the projection is missing. I opened the original file in ERDAS, and get the projection (Lat/Lon, WGS84), but I cannot find the "map coordinates of tie point". Does anyoen know how to get that info.? I'll very appreicate your help! Thanks very much!
