Structural Building Area Interface Chart 2018

The Structural Building Area Interface Charter 2018 is a product of the Soil Occupation Monitoring System (SMOS), an innovative initiative, designed and developed by the Directorate-General of the Territory, with the aim of continuously producing cartographic information on land use and occupation. SMOS uses the latest developments in space technologies and Artificial Intelligence to create products with more detail, quality, speed and made available with open data policy.All products can be viewed in vismos. https://smos.dgterritorio.gov.pt/vi-smos This product represents the segments that integrate the perimeter (interface) of the Charter of Building Areas (2018), classified according to their proximity to covered fuel (2018). This type of cover was identified based on the classes of the Land Use and Occupation Charter (COS) that burned the most in the period 2010-2018. In the production of this chart the perimeter of each area built (2018) was subdivided into segments of irregular size, resulting from the analysis of the type of cover (fuel vs. non-fuel) around the built area.In the perimeter subdivision it was ensured that each segment was adjacent to a single type of cover. Subsequently, each segment was classified according to its proximity to fuel cover in one of the following types of structural interface: • Direct: segments that are in immediate contact with covered fuel. Indirect: segments that distance up to 500 meters of covered fuel. * Null and void: segments that are more than 500 meters of covered fuel. This product was developed by DGT under the project POSEUR-02-1810-FC-000504 and represents the old Charter of the Urban-Rural Interface 2018, whose designation was changed in line with the terms used by the Legal Framework of the Integrated Rural Fire Management System (DL 82/2021). DGT currently produces two types of Built Area Interface Cards: the structural and the conjunctural. In addition to small methodological differences in their production, these two charts differ in the source used to identify the fuel cover. In the structural chart the fuel cover is identified through the COS and in the conjunctural chart the fuel cover is identified through the Conjuncture Soil Occupation Chart (COSC).These two maps have different minimum cartographic units (UMCs), i.e., the COS has a UMC of 1 ha and the COSC has pixels of 10 m, but the main difference is due to the fact that the COS is a land use and occupation cartography and the COSC of land occupation. For example, an area of forest use in the SOC can be classified in COSC as Matos or spontaneous Herbaceous Vegetation if in that year it is temporarily deforested.
