etopo1

GMT (Generic Mapping Tools) shell scripts building 3D perspective relief models of the Kuril-Kamchatka Trench: grdview topographic/bathymetric meshes from ETOPO relief overlaid on 2D EGM96 geoid contours, rendered at two perspective azimuths (135 and 165 degrees).

GMT (Generic Mapping Tools) shell scripts extracting and stacking serial cross-track bathymetric profiles across the Kuril-Kamchatka Trench (north and south segments) with grdtrack, plotting median stacked profiles with error envelopes over a shaded-relief basemap.

Collection of ~180 GMT (Generic Mapping Tools) shell scripts producing shaded-relief topographic and bathymetric maps of countries and regions worldwide from global DEMs (ETOPO1, GEBCO, SRTM, GLOBE), with DCW country clipping, custom CPTs, contours and cartographic layout.

GMT (Generic Mapping Tools) shell scripts mapping ETOPO1 bathymetry of the Mariana Trench in three contrasting map projections: Cassini transverse cylindrical (-JC), Cylindrical Equal-Area Gall-Peters (-JY) and Polyconic (-JPoly), with colour scale, contours, toponymy and geometric-shape annotation.
