Hi, when I use an external DEM I always get the same result on the SARPROZ monitoring screen.
What does It means? my DEM is georreferenced and I tried to load the DEM with UTM and GEO coordinates. But It seems my DEM isn’t working or his reference is wrong.

Also, when I apply it in small areas, the residual height is equal to the total height.

Thanks, David S.

what do you mean that you get the same result??
you DEM must be in geographic coordinates: make sure this is correct
then, to check if it is ok or not, plot it.
with the “DEM visualization” button u see the DEM in geographic coordinates, and u should notice 4 black crosses showing the position of the footprints of your sar dataset
then, in view extended data u can plot the DEM in SAR coordinates.
if those pictures are ok, everything works properly
otherwise, pleas post both pictures and more infos
best

Hi,

I am trying to use ALOS 12.5 m DEM as external DEM.
But whenever I am visualising it is not satisfying.
KIndly suggest on how to reproject?? I mean which system. THe DEM I am using is in WGS_1984_UTM_zone_43N.

Thanks.

as it is written above, the DEM must be in geographic coordinates (latitude and longitude)
