Gran Paradiso: grassland change map (2012-2016)

<p>A change map for the land cover class &quot;GRASSLAND&quot; in &quot;Gran Paradiso&quot; PA, obtained by the Cross Correlation Analysis algorithm (CCA) [1,2] considering at time T1 the layer &quot;GRASSLAND&quot; from COPERNICUS Service VHR layer dated 2012 and at time T2 a Sentinel-2A image dated August 13rd, 2016.</p> <p>The map was produced at 20 meters spatial resolution and projected in WGS84/UTM32N.</p> <p>The map has binary values where value 1 indicates pixels changed from GRASSLAND to other whereas value 0 indicates No changed/Not considered pixels.</p> <p>The Overall Accuracy (OA) of the map was: OA=93.16%&plusmn;0.14%.</p> <p>[1] Koeln, G., &amp; Bissonnette, J.
