Glitch in Italy (Adriatic Sea) #58

Closed FReddig closed 3 years ago

FReddig commented 3 years ago

Hello everyone,

I have a problem concerning a DEM for the Mediterranean which I need for a SDM (see image). There seem to be a problem in the Adriatic Sea: 2021-06-07 (3)_LI

Can someone provide me a little support on how I can fix this problem? I used set the neg_to_na equals TRUE, since I just want to use land and not under sea floor DEM.

Code:

mediter_elev_raster <- get_elev_raster(locations = xy_df, z = 8, prj = proj_medit, neg_to_na = TRUE, src = "aws", clip = "bbox", override_size_check = TRUE) # neg_to_na refers to elevation that is a.s.l. If we would not add this information, we would obtain DEM also from the sea ground. But we just need landsurface (a.sl.).

Thank you very much in advance, Fabian
