Another Big Update of the Digital Elevation Matrix for MLinkPlanner and RadioPlanner

We continue to update the digital elevation matrix (DEM) for MLinkPlanner and RadioPlanner. In addition to the recent massive update, we have replaced SRTM1 Worldwide Elevation Data with ALOS World 3D - 30m (AW3D30) for South America, Africa, Asia, Middle, and Far East regions.

ALOS World 3D - 30m (AW3D30) is a 30-meter resolution DEM captured by the Japan Aerospace Exploration Agency (JAXA). https://www.eorc.jaxa.jp/ALOS/en/aw3d30/

Recently, this DEM has been made available to the public.

This DEM has higher accuracy compared to SRTM1, which was previously used for these regions. This will allow for more reliable coverage and link predictions.

It is the most precise global-scale elevation data now:

RadioPlanner and MLinkPlanner DEMs Update

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)

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:

C:\Users\user\AppData\Roaming\RadioPlanner\data\

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.
