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.

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 On 7/18/25 05:05, Michael Smith via gdal-dev wrote: > All, > > Is there an gdal raster reproject equivalent command to gdalwarp -rpc > (which we use for NITF files with RPC georeferencing information? > Additionally, is there a gdal pipeline way to use info as the last step > rather than writing a file?
