Description
When using RPC transformer with a RPC_DEM, transformations fail if the point is outside of the DEM area or is on a nodata pixel of the DEM. This might be a reasonable behaviour for some applications. But sometimes those missing values just fall in oceanic areas, so it might be desirable to have an option to gracefully continue the processing.
