Gran Paradiso: grassland change map (2012-2016)

A change map for the land cover class "GRASSLAND" in "Gran Paradiso" PA, obtained by the Cross Correlation Analysis algorithm (CCA) [1,2] considering at time T1 the layer "GRASSLAND" from COPERNICUS Service VHR layer dated 2012 and at time T2 a Sentinel-2A image dated August 13rd, 2016.

The map was produced at 20 meters spatial resolution and projected in WGS84/UTM32N.

The map has binary values where value 1 indicates pixels changed from GRASSLAND to other whereas value 0 indicates No changed/Not considered pixels.

The Overall Accuracy (OA) of the map was: OA=93.16%±0.14%.
