AWI Basemap

Utility to create the AWI Basemap.

Description

The AWI Basemap is a global basemap for GIS applications or web map viewers. The map is a rendered and shaded RGB version of the current GEBCO grid with ice overlays from ADD, GLIMS and GIMP. It is available in three projections, EPSG:4326 for the global map as well as EPSG:3995 and EPSG:3031 for the polar stereographic versions.

The basemap is an RGB GeoTIFF created from various geodata sources that need to be analysed (hillshade, slope), converted (raster to vector, vector to raster calculation), combined, colored and rendered to RGB. To ease the update process (e.g. new GEBCO version or any other data sources updated) this git provides the tools to create and update the AWI Basemap, as well as scripts to automate the process.

At this point, the AWI Basemap is created in three color sets. They are based on the AWI blues (light: 0/172/229, dark: 0/62/110). Yet, the colors are toned down in their saturation to create a more pleasing viewing experience.
