dem - Is there a way to programatically force RGB (3 bands) in a raster with arcpy?


I'd like to include conversion to a 3 band RGB raster in a script to prepare multiple DEMs for image processing. The input files are rasters extracted from a raster mosaic.


The manual option is to use the Export Data option in the TOC, but I have to repeat this for 15-25 different rasters so I'd like to automate it.


Each input raster is a single band that I'd like to force RGB like the image below (maunal method).

Answer




I got some help from an ESRI employee. Apparently there isn't a Python method available to accomplish this, but you can export a Raster and force RGB through ArcObjects (IRasterLayerExport Interface).
