Open Digital Elevation Model (OpenDEM)
The Portal for sharing the 3rd Dimension
BathymetrySearcher map client for free available bathymetry data now online.
Most bathymetry data is the product of scientific work and is unfortunately not available under free licenses in the sense of the Open Knowlege Network.
But all data presented here is at least usable without permission for scientific research, environmental conservation, education or other non-commercial purposes.
Only larger marine regions are taken into account.
OpenDemSearcher: Now also free middle resolution DEMs available.
Over 60 datasets now covering complete or large parts of north-america, australia and europe.
The digital divide is obvious on the picture on the right (in red covered areas). We hope to bypass the divide by tools for volunteered geographic information in the future.
Happy New Year!
2017 is starting with an update of the OpenDemSearcher. More than ten high resolution DEMs have beed added, including parts of Germany, Belgium, New Zealand and Switzerland. North Rhine-Westphalia for example is the most populated federal state in Germany.
