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:

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.
