Make_dem.csh in GMT problem

Q&A
1

I have a problem about DEM download using built-in script make_dem.csh in GMT. When I run this script the following error occurs:

START: make_dem.csh

grdcut [ERROR]: Remote download is currently deactivated grdcut [ERROR]: Unable to obtain remote file @earth_relief_03s rm: cannot remove ‘geoid_resamp.grd’: No such file or directory

created dem.grd, heights relative to WGS84 ellipsoid

END: make_dem.csh

I would appreciate if you could help me handle this issue Thank you so much.

Hello @Mojtaba0131,

welcome [again] to the GMT forum :slightly_smiling_face:!

Can you please provide the code related to the script make_dem.csh. Knowing your code makes it much easier for people to help you.

Maybe this line solve your issue.
gmt set GMT_DATA_UPDATE_INTERVAL=1d

Mm, you could also have problems if you use a proxy to connect to internet.

If so, see this link:

Hm. Can you please state the GMT version you are using? For this you can run gmt --version in a console.

For me, it looks like the problem is related to downloading the dataset itself, not specificly to the script make_dem.csh. So, please run

gmt grdcut @earth_relief_03s -R-115/-112/32/35 -Gearth_relief_03s.grd -V

and

gmt grdcut @earth_relief_05s -R-115/-112/32/35 -Gearth_relief_05s.grd -V

and report the output.

Did you try changing the GMT_DATA_SERVER (see also Mirrors — The Generic Mapping Tools)?

Could it simply be a firewall problem ? It just seems that you can’t connect to remote servers.
