My ultimate goal is to create a DEM of a large portion of land (spanning multiple counties) in New York, using thousands of .img files that cover my Area of Interest. With very limited experience with this, my question is: What is the very best way to go about this? If I were to guess, I would say the best way would be to create a mosaic dataset, and add all the individual .img files to it, correct? But I know mosaic datasets can get complex, so what are some of the finer details I should be concerned with? A few specifics: The .img files are a mixture of 1-meter and 2-meter resolutions My final DEM will need to be projected in State Plane NY East Currently, pixel values are in meters, but will want them in feet Each .img files is about 9 MB Any and all feedback/references (i.e., videos, articles, or any type of instruction/guidance) are welcome . Let me know if more information is needed. Thank you!
