I am trying to orthorectify satellite imagery with a DEM in ArcMap. I have already georeferenced the raster.

The imagery came with an RPC TXT file, but when I change the name of the RPC file to match the new, georeferenced raster image (by adding a "1"), the tile is completely shifted and partly clipped when I use the "Create Ortho Corrected Raster Dataset" tool.

Original file name: *******0004.tif
New file name:      *******00041.tif (I added the "1" to RPC file to match this).

Do I have bad RPC data?

    If I understand correctly, an RPC file contains some georeferencing information. Did you georeference to TIFF to the same coordinate reference system that the RPC is referring to? – mkennedy Jan 16 '15 at 17:36
  • To my knowledge the RPC file contains an abstract of the sensor/camera math. I did not see any evidence of a georeference in the file. The imagery was left in its native Datum, WGS84. – Devin Jan 16 '15 at 19:21
  • RPC is something new to me but this might be worth reading geotiff.maptools.org/rpc_prop.html. – user30184 Jan 16 '15 at 22:08
  • If you manually georectified a raster you invalidated the RPC. The RPC is the full ortho details. – BradHards Jan 16 '15 at 22:58
