my question is how to go about mosaicking ~120GB, 1200+ tif files into one raster within ArcMap. I am currently splitting up the region in smaller sets and then plan to mosaic all these together to form the one final file at the end. I'm using the Mosaic to New Raster tool. The reason I need a single file is so I can use ENVI classification functions on it.
Does anyone know if ENVI can use an ESRI Mosaic Dataset? Is there a better way to go about this (e.g. file type, etc)? I'm using unsigned 8bit data, 4 band imagery. It's taking a long time and I don't know if ArcMap will even be able to mosaic the total, final file at the end of this. I feel like this is one of those "I don't know what I don't know" problems. What am I missing?
