Project Activities
The three projects DUSAF2001, DUSAF 5 and DUSAF 6 consisted of updating the land use/land cover geodatabase of the entire regional territory using the orthophoto respectively of the years 2000, 2015 and 2018.
It was carried out in a GIS environment through the interpretation of digital orthophotos in true and false colors (le latter with a near infrared band), satellite imagery and the help of ancillary data, with the detail comparable to the 1:10,000 scale.
The interpretation, performed by modifying and/or integrating the existing information layers (areal and linear) both as geometry (maximum tolerance 0.5 mm at 1:10,000 scale) and as semantics, was based on the established DUSAF legend at the 5th classification level.
The final product is formed by a polygonal information layer, concerning the various classes of land use/land cover, and a linear layer representing hedges and rows of vegetation.
