HISDAC-ES: Historical Settlement Data Compilation for Spain (1900-2020)

Abstract

The historical settlement data compilation for Spain (HISDAC-ES) is a geospatial dataset consisting of over 240 gridded surfaces measuring the physical, functional, age-related, and evolutionary characteristics of the Spanish building stock. We scraped, harmonized, and aggregated cadastral building footprint data for Spain, covering over 12,000,000 building footprints including construction year attributes, to create a multi-faceted series of gridded surfaces (GeoTIFF format), describing the evolution of human settlements in Spain from 1900 to 2020, at 100m spatial and 5 years temporal resolution. Also, the dataset contains aggregated characteristics and completeness statistics at the municipality level, in CSV and GeoPackage format.<b>!!! UPDATE 08-2023 !!!: We provide a new, improved version of HISDAC-ES. Specifically, w</b><b>e fixed two bugs in the production code that caused an incorrect rasterization of the multitemporal BUFA layers and of the PHYS layers (BUFA, BIA, DWEL, BUNITS sum and mean). Moreover, we added decadal raster datasets measuring</b><b> </b><i><b>residential </b></i><b>building footprint and building indoor area (1900-2020), and provide a country-wide, harmonized building footprint centroid dataset in GeoPackage vector data format.</b>File descriptions:Datasets are available in three spatial reference systems:<b>HISDAC-ES_All_LAEA.zip: </b>Raster data in Lambert Azimuthal Equal Area (LAEA) covering all Spanish territory.<b>HISDAC-ES_IbericPeninsula_UTM30.zip: </b>Raster data in UTM Zone 30N covering all the Iberic Peninsula + Céuta and Melilla.<b>HISDAC-ES_CanaryIslands_REGCAN.zip: </b>Raster data in REGCAN-95, covering the Canary Islands only.<b>HISDAC-ES_MunicipAggregates.zip:</b> Municipality-level aggregates and completeness statistics (CSV, GeoPackage), in LAEA projection.<b>ES_building_centroids_merged_spatjoin.gpkg:</b> 7,000,000+ building footprint centroids in GeoPackage format, harmonized from the different cadastral systems, representing the input data for HISDAC-ES.
