DigitalGlobe images

AliceBaldridge

I just got some digitalglobe data that I would like to orthorectify.  The instructions on the desktop help assume that the RPC files are in the format .rpg (http://help.arcgis.com/en/arcgisdesktop/10.0/help/index.html#//009t000000ms000000), however, the data I received is in DIMAP format so the RPC files are in xml.
Not sure what to do with this, when I open the image in Arc, it doesn't recognize that there are ortho files.  Thanks  for your help!

I can open the Pleiades raster in XML format in Arc, but it only partially draws the layer.  So Arc, sort of recognizes it.  I can also open it easily in ENVI, but in none of the formats I save it in does Arc recognize the geospatial data.
It seems sort of ridiculous to have to go through the process of defining the spatial reference information when it is in the ancillary XML file (and ENVI recognizes it).
...

If ENVI is available to you, it is good idea to directly use it for orthorectificaon. Just make sure that GCP (ground control points) should be collected and combined into the workflow in ENVI 5.0 SP3. (In fact, it should be optional, i.e., with/without GCP).

With 10.2, we can drag-drop DIM images into ArcMap without problem (see the attachment).

However, ArcGIS 10.2 might have bugs to smoothly load/orthorectify Pleiades DIMAP images into MD (SPOT6 DIMAP/ SPOT 5 DIMAP neither), at least, in most scenarios. I believe, it is challenging to deal with DIMAP images from Astrium in ArcGIS 10.x�?�
