I have a problem with saving as GMT in QGIS. There is no option in my QGIS version to save as in GMT. How I can add this option in QGIS?
In the OSGEO4W shell, run
ogr2ogr --formats|sort to see if you have the
OGR_GMT driver (running GDAL 2.x) or
GMT driver (running GDAL 1.x) included.
If yes, you can convert your vector data with
ogr2ogr -of OGR_GMT or
If you have raster data, run
gdalinfo --formats|sort to look for the
GMT driver, then take
gdal_translate -of GMT.
This same question was asked, and answered, in the GMT forum https://gmt.soest.hawaii.edu/boards/1/topics/8087?r=8088#message-8088
-Regarding the raster matter, it's not advised to convert grids into the old GMT netcdf grid format. Just don't convert it. GMT can recognized all GDAL formats natively (it uses GDAL to read them).
