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

[Michael Smith]

Frank,

Thanks for that, I can confirm I get the same results with gdalwarp -rpc and gdal raster reproject --to METHOD=RPC. I’ll create a doc ticket to preserve this.

Michael,

If you were depending on -rpc to force use of the RPC method instead of geotransforms for instance, it might be sufficient to pass -to METHOD=RPC to things that take transformer options. 

Best regards,
Frank

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
