Building(s and) cities: Delineating urban areas with a machine learning algorithm - City & Employment Centre Boundaries (v1)

dataset
posted on 08.01.2020 by Dani Arribas-bel, Miquel-Angel Garcia-Lopez, Elisabet Viladecans-Marsal
City and employment centre boundary delineations for Spain (except Basque Country and Navarra), based on building footprint from the Cadastre, and created using the A-DBSCAN algorithm.

GeoJSON polygons expressed in WGS-84 (ie. lon/lat), GeoPackage polygons expressed in ETRS89 / UTM zone 30N (EPSG:25830).

Files included in this dataset:

- sp_blg_adbscan_city_boundaries_v1.geojson: city boundaries in GeoJSON format. Each boundary contains a city ID (city_id in the table) and the number of building footprints it contains (n_buildings in the table).

- sp_blg_adbscan_city_boundaries_v1.gpkg: city boundaries in GeoPackage format. Each boundary contains a city ID (city_id in the table) and the number of building footprints it contains (n_buildings in the table).

- sp_blg_adbscan_emp_centre_boundaries_v1.geojson: employment centre boundaries in GeoJSON format. Each boundary contains a city ID (city_id in the table), an employment centre ID (centre_id in the table) and the number of building footprints it contains (n_buildings in the table).

- sp_blg_adbscan_emp_centre_boundaries_v1.gpkg: employment centre boundaries in GeoPackage format. Each boundary contains a city ID (city_id in the table), an employment centre ID (centre_id in the table) and the number of building footprints it contains (n_buildings in the table).
