ENVI .hdr ingestion puts RPC information in non-standard metadata tag

[cjanssen]

The RPC information read from an ENVI header file in the ENVIDataset::ProcessRPCinfo function is placing the values in a nonstandard metadata tag. Its currently placing the metadata in the default domain with the "RPC_" prefix on each tag. I believe the appropriate action is to place the values without the prefix in the RPC domain of the metadata. I have attached a sample .hdr file.

I tried working with this hdr but it has a file type of "TIFF" while it appears the current ENVI driver only supports raw files labelled with ENVI .hdrs.

Were you able to use this file?

Sorry about that, I re-exported the file out as an ENVI Standard format, I believe this is a RAW. I checked GDAL 1.6.1 and it will load it just with the RPC info out of place.

I have adjusted the RPC metadata handling in trunk (r17396).

This area would benefit from a regression test!

Regression test added in :

r23898 /trunk/ (4 files in 3 dirs): ENVI: add support for writing RPCs and GCPs (partial merge of r23847 from 1.8-esri)
