BSQ File import as raster

Does GM12 default to importing BSQs as elevation always or is there some setup I can change to make it read it as raster? It is causing me some issues with conversion to GTiffs with new 8bit external palette assigments I think.thx

    That would be determined by the header and layout. Anything with multiple bands should come in as imagery automatically. With a single band image without anything special in the header it can be tricky but normally you will be asked if the layout is not obvious. What is the layout of your BSQ file?

    Thanks,

    It looks like that file has 4-byte float samples (data type 4 in ENVI headers is float). A 4-byte float single band file will always be interpreted as terrain. Should this actually be imagery?
