Hi,
I'd be interested in people's feedback about which "sidecar"/external
files for
GeoTIFF to store RPC (Rational Polynomial Coefficients) are the most
popular
those days and how well they are supported by the various remote
sensing
software
packages. Besides reading/writing the TIFF RPC tag
(http://geotiff.maptools.org/rpc_prop.html), GDAL can read/write the
.RPB format
as found in Digital Globe products, as well as read the _RPC.TXT
format a found
in GeoEye products. This support dates back to some time ago, so I'm
wondering
if there have been change in that area.
Not that I have much to offer in terms of support. Some sort of a
feedback though: I have used, last year, many and different very high
resolution products (QB2, IKONOS, WV2). For all of them, GDAL worked
nice in using the existing RPC metadata (packed inside a NITF or
stored inside RPB files) to warp images.
