Terrain Correction using Several External DEM Tiles over a large area

Microwave Toolbox
#1

Hi Everyone

I would like to use my own higher resolution DEM for a terrain correction operation over a large area. The DEM data is split into 5kmx5m tiles.

Will I have to make a tiff mosaic of all these tiles and specify that during Terrain Correction OR is it possible to specify a folder (containing DEM tiles) location and SNAP can read the DEM tile headers to work out which tiles are needed e.g. in the same way SRTM tiles are imported?

Thanks,
Sanj.

Using a folder for an external DEM is in our list of things to do. Currently, you will need to mosaic and create a single file.

Is there any news on this?
It would be great to use external DEM tiles instead of one big mosaic.
