Web Map Services (WMS)
Since we at mundialis want to give back to the community, we have prepared a series of Web Map Services based on open access data. This site gives you an overview of the web services we provide for free. They comply with the Web Map Service Specification of the Open Geospatial Consortium (OGC).
You may use them free of charge as background layers for your application. As we offer it as a free service, we do not guarantee any continued availability. Of course we do our best to keep them up & running!
If you have any questions regarding this or are interested in a modification of one of the services, please contact us.
The service URL for all our services is:
Layer Name: TOPO-WMS
This service shows the topography of the world. For now the spatial resolution is limited to 450m for SRTM but we will continue to add data at higher resolution like this is already the case for Germany with a resolution of 30m as provided by Aster DEM. We coloured the data according to its height using OGC’s Styled Layer Descriptor Standard. It offers to describe a ‘ColorMap’ and tell the service to render certain height values in certain colours. We added about twelve gradations.
But not only the topography is part of our topography layer. We added bathymetry of the ocean as well as bathymetry of the great lakes in the USA.
The WMS is published via GeoServer and cached it with MapProxy. As topography doesn’t change too often, GeoServer calculated the tiles in predefinded zoom levels and MapProxy delivers them to the user. As pixels get visible due to resolution, it is not necessary to cache them at a high zoom level, but possible to calculate them out of existing cached tiles. This leads to a high performance in general.
Topographic OSM WMS
Layer Name: TOPO-OSM-WMS
This service is a combination of the TOPO-WMS and of a new service by terrestris – the ‘OSM-Overlay-WMS’. The overlay shows cities, streets and municipalities by Open Street Map data. As it is only an overlay, it is possible to impose it on different layers, e.g. our TOPO-WMS.
Combining the two existing services, the new service adds OSM data to topographic information of the world.
