I have around 1300 .hdf files to be georeferenced and i have downloaded the LAT/LONG Grids from NSIDC website http://nsidc.org/data/doc...ture/geolocate.html. Since it is time consuming, i tried to batch georeference the files usind an IDL programme. After compiling it, three .bin files are created. I tried to import it into ERDAS and its not working. Can you please tell me what the binary file contains. How can it processed it in ERDAS.
