Murgia Alta: grassland change map (2012-2015).

Murgia Alta: grassland change map (2012-2015). A change map for the land cover class "GRASSLAND" in "Murgia Alta" 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 7th, 2015. The map was produced at 20 meters spatial resolution and projected in WGS84/UTM33N. 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=94.21%±0.10%. [1] Koeln, G., &amp; Bissonnette, J. (2000).
