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:
