Configurable base map #11

Closed mzur closed 3 years ago

SRTM30_PLUS is a publicly available global elevation dataset. It's free of charge for academic purposes. With a color map to separate sea (<0) and land (>=0) it gives a nice world map:

We already converted it to Zoomify tiles in /vol/uwi/seamap/topo_zoomify_tiles. The dimensions are 43200 x 21600 pixels and the projection is EPSG:4326.

Update the geo module to use OpenStreetMap by default. Then implement a config to allow setting a custom map source like our SRTM30_PLUS Zoomify tiles. If the config is set, use this source instead. Find out the required attributions.

ETOPO1 although not that fine-grained 1 min instead 30 sec looks much nicer and is also free of charge: https://www.ngdc.noaa.gov/mgg/global/

mzur commented 6 years ago

ETOPO1 is now in /vol/uwi/seamap/ETOPO1_Ice_g_geotiff.tif.

I could generate a relief color image for the SMRT_PLUS 15/30 dataset but the colormap would still not be that fancy. Added color version of etopo1 to folder

The Geomar people have an OGC "Web Tile Service" (GeoMapApp) running in house and plan to set one up on their ships, too. This service can provide the image tiles of arbitrary world maps or even only parts of maps. On the ship, it would be able to provide bathymetry maps, trajectories etc. live generated by the ship.

I think it would be a nice solution for this issue to simply implement support for Web Tile Services in this module. This way, we don't have anything to do with generating or storing the map tiles which has nothing to do with the main application focus of BIIGLE.

The Geomar people also mentioned the GEBCO world map.

This will be obsolete through #18.
