Basemap

Utility to create the AWI Basemap for maps.awi.de, data.awi.de and marine-data.de.

Description

The above mentioned websites use a global basemap with a colored and shaded digital elevation model (DEM) as a background. This 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 ofther 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 Basemaps is available in three color sets. All three are based on the AWI blues (RGB bright: 7/172/231, RGB dark: 0/62/110). Yet, the "default" color palette reduces these blues to half their saturation, the "bright" color palette uses the blues directly, and the "dark" color palette uses the blues with a quarter of their saturation.

Instructions

INSTRUCTIONS.md holds the instructions on the usage of the scripts to create the AWI Basemaps.
