Images of changes between 2012 and 2008 in the use and coverage of Andalusia (SPOT5 HRG XS + PAN)
Description
Layer of forest and agricultural changes between 2012 and 2008, calculated from the differences between the SPOT5 images of both years (multispectral and panchromatic bands). The change layer is obtained by unsupervised automatic classification, aimed at detecting changes in the legend of the forest and agricultural classes of SIOSE-Andalucía. Within the agricultural class there is a difference between arable and woody crops. Therefore, 4 layers of change are obtained: changes in the forest area, arable crops, woody crops and unproductive soil. For arable crops, the LPIS-GIS classes arable land and orchard have been considered; 16 LPIS-GIS classes (fruit-citrus, citrus, peel-citrus fruit association, vine-citrus association, fruit-peel association, peel/olive fruit association, peel fruit association, peel/vine fruit association, fruit, olive island, olive-citrus association, olive-fruit association, olive grove, fruit-vineyard association, vineyard, olive-vineyard association). In the unproductive, which includes that SIGPAC class, a 10 m buffer has been made to ensure that at least one pixel is evaluated with the SPOT images. The results are obtained in 10 m spatial resolution raster format, where change images and change images are included with a 3x3 pixel fashion filter. The series comprises the images corresponding to the change layers of scene 040275. Also included in vector format are the change layer of the different strata, the shapefile of the work unit, the cloud layer, forest area, agricultural area with woody, herbaceous and unproductive crops.
