I am GMT user from Nepal.map of Nepal has been changed but GMT is using the old map.how can I get modified map of Nepal in GMT
Hello. What do you mean with “changed”? The borders?
I think the borders and coastlines in GMT are mostly from 1970’s databases, so more recent changes than that are not in the default GMT “coast” plotting. If you want a more recent border database, you may need to get it from another source like OpenStreetMap and convert it to GMT format for plotting.
If yes, you can extract them on https://osm-boundaries.com/. Next step would be converting them with GDAL to a GMT-readable format. Now you can plot them with GMT.
