Chris,<br><br>This could happen when you try to transform an image that is outside the defined area of the destination projection.<br>Cut the raster to the destination projection's extents and try again.<br><br>There is a thread with exactly the same error message in the archives[1]. I am not sure that it can help with your case, but try it anyway.<br>

<br> gdalwarp -rpc raw.tif out.tif<br><br>with a raw.tif and raw.rpb file, the image "orthorectifies" correctly. The moment I run:<br>
<br> gdalwarp -rpc -to RPC_DEM=dem.tif raw.tif out.tif<br><br>I get the following error:<br><br> ERROR 1: Too many points (441 out of 441) failed to transform, unable to compute output bounds.<br><br>I've attached the info of raw.tif. Does anyone know what went wrong, and is this beacuse of DEM, or is it another problem?<br>
