Hi all,
I am trying to orthorectify a couple of aerial photos using gdalwarp,
but i am stuck with the /-to /transformer option. I have seen in archive
two request concerning this issue, but without any answer for now... so
hope this 3rd will have a reply ;)
materials :
scan of an old aerial photo, without fly info and, of course, without
projection, tif format
Dem of the region, tif format
what i've done :
using qgis georeferencer to grab some GPC's on the aerial photo
using gdal_translate to insert GPC's in the aerial photo
what i've try :
using gdalwarp to transform, rectify and project the aerial photo with :
/gdalwarp -to RPC_DEM=dem.tif -t_srs=EPSG:2154 input.tif output.tif/
result:
my file is transformed and projected but not rectified. Option /-to
RPC_DEM /is ignored by gdalwarp, even if I write wrong option like /-to
RP_D...
/Am i doing something wrong ?
thanks for reply
Alain
