Hi, I would like to use IDL to batch process files from a data collection. In ENVI, I use the "Georeference from IGM" command and then "Save As Tiff" to write the resulting georeferenced image as a GeoTiff file. How do I call these two ENVI commands from IDL? Thanks, Keith

You can use ENVI_GLT_DOIT to build the GLT from the lat/lon bands and then ENVI_GEOREFERENCE_FROM_GLT_DOIT. If using ENVI 5.1, you can use the new routine ENVIGLTRasterSpatialRef. ENVI_OUTPUT_TO_EXTERNAL_FORMAT can be used to save to TIFF, or if using the new routines, use the Export method to ENVIRaster.
