You can't. The NITF driver doesn't support setting GCPs in the imagery itself.
When it reports GCPs while reading a NITF file, it takes them from the IGEOLO
record that can contain up to 4 GCPs. But AFAIK, it wouldn't be easy to *set*
arbitrary GCPs, as there must be necessary the 4 corners of th
hi list,
I have run the following Python codes to add more GCPs to RSAT-2's
single channel GeoTiff imagery_HH.tif.
But when I apply it on RSAT-2 NITF format imagery_HH.ntf, all the GCPs
went to an anxiliary file "imagery_HH_GCPs.ntf.aux.xml".
How can I add the GCPs directly into imagery_HH.ntf?
Frank,
Interesting. I'm attempting to use Mapserver -> OGR -> VRT -> ODBC ->
SqlServer2000 -> a table of 250k rows of point features.
Testing with ogrinfo to return all the rows takes about 25 seconds, but with a
"-spat" to get about 3000 rows takes < 2 seconds (very acceptable). And I

Yes. The OGRLayer has a SetSpatialFilter() method for this. Some drive
