Trece is a CLI tool for downloading and managing authoritative Spanish geospatial and address data, including administrative boundaries, road networks, postal codes, and address points for all Spanish provinces. The data is sourced from CartoCiudad, an official national geospatial database maintained by the Instituto Geográfico Nacional. Refer to Data Source and Attribution for more.

CartoCiudad data is widely used for mapping, spatial analysis, urban planning, and research. The data is open, regularly updated, and available in various formats suitable for GIS and data science workflows.

Each province's dataset is distributed as a GeoPackage (.gpkg) file, a spatial database format that supports multiple vector layers. It includes two main layers

• portalpk_publi: Point layer representing address portals (building entrances) and kilometer markers along the road network. Each record contains

  • id: Unique identifier
  • geom: Point geometry (location)
  • id_porpk: Portal or kilometer marker ID
  • tipo_vial: Type of road/street
  • nombre_via: Street name
  • numero: Street number or kilometer
  • extension: Additional address info
  • dgc_via: Road code (from Dirección General de Catastro)
  • id_pob: Population entity ID
  • poblacion: Population entity name
  • cod_postal: Postal code
  • tipo_porpk: Portal/marker type
  • tipoporpkd: Portal/marker type description
  • fuented: Data source
  • fecha_modificacion: Last modification date
  • municipio: Municipality name
  • ine_mun: Municipality code (INE)
  • provincia: Province name
  • comunidad_autonoma: Autonomous community name

• manzana: Polygon layer representing cadastral blocks (manzanas) as defined by the Spanish Cadastre and regional authorities. Each record contains

  • id: Unique identifier
  • geom: Polygon geometry (block shape)
  • ID_MANZ: Block identifier
  • ALTA_DB: Database registration date
  • INE_MUN: Municipality code (INE)

Coordinate Reference System:

• Mainland Spain and Balearic Islands: ETRS89 (EPSG:4258)
• Canary Islands: REGCAN95 (EPSG:4081)

All attributes are standardized for integration with GIS and spatial analysis tools. The data structure and schema are consistent across provinces, enabling automated processing and analysis.

• Fast & Simple: Download CartoCiudad data for all Spanish provinces with a single command.
• Province Selection: Choose a province or fetch all at once.
• Scriptable: Easily integrate into your data pipelines or automation scripts.
