GIS analysis

We have a rich toolset of high profile GIS algorithms available, in fact we are also co-developing a GIS system. This page illustrates some examples of our analytical work.

Solar radiation based on high resolution DEM

The map shows the aggregated astronomical insolation time in hours of the second week of a year in Northern Italy (Garda Lake). The map is terrain-shaded to deliver an impression of the complex geomorphometry in the area. The calculation was performed in the open source software GRASS GIS (http://grass.osgeo.org/) and is based on a high resolution elevation digital model (5m x 5m) derived from Lidar scanning by airplane. The insolation algorithm takes terrain shadows into account, cloud cover could be optionally considered.
