Harp Piemonte — Mosaic pictures Sentinel 2 — Fall 2017

The dataset is a mosaic of images captured by Sentinel 2A (European Copernicus programme) during the autumn of 2017. The images are appropriately mosaiced to cover the Piedmontese, Ligurian and Valdostan territories according to a series of 12 tiles and are published in natural colors: bands 4 (red), 3 (green) and 2 (blue) of the MSI sensor (13 channels in visible/infrared VNIR).Date of acquisitions: 14 October for TMP tiles — TMR — TMQ — TMS — TNP — tNQ — TNR — TNS17 October for TLP tiles — TLQ — TLR — TLSThe mosaic was realised by Arpa Piemonte as part of the activities related to the national soil consumption monitoring project 2018 conducted by the National Environmental Protection System (SNPA) through the coordination of ISPRA and the involvement of several regional agencies. 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. The methodology of analysis uses, for the first time on a national scale in a uniform and uniform way, the new Sentinel 2A/B images which, given their level of detail and the frequency of revisitation guaranteed by the Sentinel mission, allow to obtain overviews of the national territory in a regular and constant way (multi-time analysis).The comparison between these allows to highlight the main transformations of the territory and the related phenomena of land use (expansion of urban settlements, new roads, shipbuilding for new works, etc.).
