3D Rerun
There is still no snow in the Drammen area so we combined leasure with purpose on Sunday. There was good conditions for a walk in the woods, temperature around zero 'C, sun and light winds.
Orienteers in IF Sturla are looking for new areas to map and these specific hills have been in our minds for a while.
As far as we know there is no orienteering map of any kind here so I have used
programs written by Terje Mathisen
which utilizes LiDAR-data and added public mapping data.
On the second half of the tour (click on the map to swich map) we had encountered some areas with heavy logging. That was quite disappointing because the contours could offer some fine challenges in navigation.

I noticed that the LiDAR data was quite old unfortunately, from 2009!
This means that the automated vegetation classification can be OK (and better with calibration) in the old growth areas, but any logging activity, even if it took place even before the scanning date, will cause rapid changes in the vegetation.
Good luck with the new map anyway, some of the hills seems quite nice!
