Earth Terrain and Sea Map

DEM data from http://ddfe.curtin.edu.au/models/Earth2014/ (1) ( see also description at - https://www.arcgis.com/home/item.html?id=ca50c82d8dc5428f9a22268973c24031 ) The 5 arc minute data set was used. The raw data was converted to a PLY file using custom software, see https://theretiredengineer.wordpress.com/2021/01/31/earth-terrain-model-2/ Terrain colour mapping derived from http://soliton.vm.bytemark.co.uk/pub/cpt-city/td/tn/DEM_screen.png.index.html. Sea colour mapping used a custom GIMP colour gradient Original 3D file was 500 Mbytes ( >9 million verticies and >18 million faces ). Reduced to <50 Mbytes for upload ( 900,000 verticies and 1.8 million faces ) using Meshlab. Vertical scale of features magnified 20x (1) Hirt, C. and Rexer, M.
