[gdal-dev] Gdal raster reproject equivalent to gdalwarp -rpc

[Michael Smith]

>From Frank Wamerdam, the answer is to use --to METHOD=RPC.

And the pipeline would be:

gdal raster pipeline ! read /vsis3/file_P004.NTF ! reproject --to METHOD=RPC ! write /tmp/test2.gdalg.json --overwrite && gdal raster info -f text /tmp/test2.gdalg.json

Hey Mike,


For the -rpc option I *think* you can use the -to option in reproject. 
Look at the documentation at the link under -to and read that. I *think* 
what you're looking for is -to RPC_DEM=pathToDem .


For the pipeline command you can use a gdalg virtual file and "poor 
mans" pipeline in bash like:


gdal raster pipeline \
! read some.tif \
! write tmp.gdalg.json --overwrite \
&& gdal raster info tmp.gdalg.json -f text


Hope that helps,
Scott
