We are pleased to announce that we have made a massive update to Digital Elevation Matrix (DEM) for North America, Europe, Australia, and New Zealand.
For North America, 1 Arc-second Digital Elevation Model USGS National Map 3DEP is now used.
Coverage: USA, Canada, Mexico.
We now use data from open digital terrain models (DTM) from national geoservices for the following European countries:
Austria (DTM 5-10 meters)
Belgium (DTM 5-10 meters)
Denmark (DTM 1.6 meters)
Estonia (DTM 10 meters)
Finland (DTM 10 meters)
France (DTM 5-10 meters)
Germany (DTM 2-25 meters)
Iceland (DTM 10 meters)
Italy (DTM 2-10 meters)
Latvia (DTM 20 meters)
Liechtenstein (DTM 10 meters)
Luxembourg (DTM 5 meters)
Netherlands (DTM 5 meters)
Norway (DTM 10 meters)
Slovakia (DTM 10 meters)
Slovenia (DTM 1 meters)
Spain (DTM 2-5 meters)
Sweden (DTM 50 meters)
Switzerland (DTM 2 meters)
United Kingdom (DTM 2 meters)
For the rest of Europe, the European Digital Elevation Model (EU-DEM), version 1.1 is now used.
Coverage: Albania, Bosnia and Herzegovina, Bulgaria, Croatia, Cyprus, Czechia, Greece, Hungary, Kosovo, Lithuania, Malta, Montenegro, North Macedonia, Poland, Portugal, Romania, Serbia, Turkey.
For Australia, SRTM-derived 1 Second Digital Elevation Models Version 1.0 (DEM-S) is now used.
For New Zealand, the New Zealand National Digital Elevation Model a 25-meter resolution is now used.
Coverage: New Zealand
The new DEMs have higher accuracy compared to SRTM, which was previously used for these regions. This will allow for more reliable coverage and link predictions.
Attention! To use these new DEMs you need to delete the old DEM cache files that are stored on the computer.
For MLinkPlanner please clean the folder: C:\Users\user\AppData\Roaming\MLinkPlanner2\data\
For RadioPlanner please clean the folder:
For the rest of the regions, the SRTM Worldwide Elevation Data (1-arc-second Resolution SRTM Plus V3) matrix is still used.
We also plan to update geodata in the future.
