Harp Piemonte — Mapping of Soil Consumption in Piedmont 2021

The dataset represents the mapping of soil areas consumed in Piedmont as of 2021.The elaboration was carried out by Arpa Piemonte as part of the activities related to the national project of monitoring soil consumption 2022 conducted by the National System for Environmental Protection (SNPA) through the coordination of ISPRA and the involvement of several regional agencies. Last update of the map July 2022.The remote sensing monitoring process updates and integrates annually the entire historical series based on the availability of new high-resolution satellite and aerial images and models for identifying and classifying potential transformations. This allows from year to year a more accurate analysis of the territory, also integrating and modifying phenomena previously undetectable and classifiable (omissions and commissions) allowing to obtain new and more accurate estimates of the soil consumed. In this sense, thanks to the recent availability on Piedmont of recent high-resolution aerial orthoimages (e.g. AGEA 2018) has been possible to reanalyse and integrate the estimates of the annual increases in land consumption made in previous years and in particular those of the two-year period 2017-2019, previously based only on the availability of satellite images Sentinel 2 at medium resolution.The project aims to monitor the transformations of the territory due to urban, infrastructural, commercial expansions, etc. with the consequent loss of natural, agricultural and semi-natural soil, understood as an essential and fundamentally non-renewable environmental resource.
