About dem_mosaic

[Zhen Yang]

Hello everyone, 

I want to use the newly produced DEM from ASP to update the historically produced low-resolution DEM. After down-sampling the newly produced DEM, I plan to set up a buffer zone and use the lowest points of the DEM as the mosaic lines. However, there are obvious stitching seams in the mosaic line area. Can the built-in mosaic tool in ASP achieve the mosaic for updating the DEM?

Try to use dem_mosaic --priority-blending-length 100 new_dem.tif old_dem.tif -o combined_dem.tif and see if this looks better.
