Georefencing MODIS using Multiple Topographic Maps Is this possible using ENVI 4.3? Using the Registration Toolbar, I can only open one topographic map at a time. But the Satellite Image (MODIS) covers large areas that it extends to several topographic maps. If I were to register the satellite image per topographic it will really take me time. I have 50 topographic maps and 300 satellite images to georeference. Please advise. Thank you.
