Land Consumption 2006 — Dataset

National map of land consumption carried out by the National Environmental Protection System, with classification system on the first level. The production of cartography, based on satellite images (Rapideye for 2012 and Sentinel 1 and 2 from 2015 onwards), takes place through an improvement of the geometric and temporal resolution of the Copernicus territorial monitoring services, the use of semi-automatic classification algorithms and photo interpretation, at the end of which data verification and validation operations are carried out. The data have a resolution of 10 meters, consistent with that of Sentinel 2. The analysis methodology benefits from the great availability of Sentinel data that produces multi-temporal coverage of the territory to the benefit of the quality of the change detection process. The variation in spectral response with seasonality is in fact a critical element in the analysis of change detection, especially with regard to the assessment of changes in agricultural areas. During the updating of the data, the quality of the maps of previous years is revised and improved with the correction of omission and commission errors present therein and consequent improvement in the calculation of change statistics. The data are the official reference at national level for information on land consumption pursuant to Law 132/2016.
