GMT (Generic Mapping Tools) shell script processing the GLOBE DEM (Global Land One-km Base Elevation, 30 arc-second): converting raw 16-bit signed-integer binary tiles to GMT .grd grids with xyz2grd, batch mosaicking to a global XYZ, and rendering the relief.

Star 0

GMT (Generic Mapping Tools) shell script converting a regularly-spaced XYZ bathymetry table directly to a NetCDF grid with xyz2grd (exact grid registration, no interpolation), then contour-mapping the result for the Kuril-Kamchatka Trench.
