Land use and cover 2018 (DUSAF 6.0)
Description
DUSAF (destination of use of agricultural and forestry soils) is a detailed geographical database established in 2000/2001 and now in its 6th version. In this version were used orthophotos (made by AGEA, 1 pixel=0.2m on the ground), with aerial color photos taken in 2018 and images from satellite SPOT6/7 2018 (1 pixel=1.5m on the ground), as a result of unknown problems AGEA provided partial coverage of the regional territory, coma fig. 1/A, with a geographical “hole” of about 4.000 km², compensated by the aforementioned satellite images, for the area referred to in Fig. 1/B. All the regional territory was accordingly updated with regard to land use and coverage and hedges and rows to 2018. The detail is equal to an information scale of 1:10.000, namely: — for the representation of the area elements: — for each theme with an area development, the minimum representative size threshold corresponds to 1 600 m², i.e. a map area on the scale of 1:10.000 of 16 mm²; — the minimum linear dimension of the polygon is 20 m, equal to a length on the paper at the working scale of 2 mm; — for the representation of linear elements (wires and hedges): — represented if the linear development on the ground is greater than 40 m. (referred inside the individual plots on which they insist). Rows and hedges are detected when of a width of more than 5 m. With regard to the geometric changes of existing polygons, all deviations exceeding 20 meters from the existing arc independently of the surface of the modified area (which may therefore be less than the minimum mapable surface) have been considered. DUSAF 6.0 is also published in “DUSAF Time Evolution” for comparison with previous versions.
