Map data download API documentation, available via HTTP-JSON/XML service.

URL base service:

* API KEY. Same KEY used in maps API js

HTTP requests in GET or POST
Response in JSON / XML format

Download the polygon geometry (in WKT format) of a municipality or a postal code

REQUEST

Example:

&cmd=geoment&poic=D00_43157_0_0_130_66_2&tolerance=0&cs=4326

Where:

  • munc / pcode / poic= Municipality ID / Postal Code
  • ctryc= country code (ISO 3 digits). Mandatory for &pcode=
  • tolerance= polygon simplification, in meters. If 0, returns the original data
  • cs= coordinate system of the data. Use 4326 for geographical system lat,long

Example:

  • Zaragoza municipality (Spain): cmd=geoment&munc=ESP502973&tolerance=0&cs=4326
  • London municipiality (Westminster, UK): cmd=geoment&munc=GBRE02AP&tolerance=0&cs=4326
  • Postal Code 06405 (USA): cmd=geoment&pcode=06405&ctryc=USA&tolerance=0&cs=4326

Response includes a WKT with the route polyline, using standard "Well-known Text Representation for Geometry".
 

Geometry Type Text Literal Representation Comment
Point 'POINT (10 10)' a Point
LineString 'LINESTRING ( 10 10, 20 20, 30 40)' a LineString with 3 points
Polygon 'POLYGON ((10 10, 10 20, 20 20, 20 15, 10 10))' a Polygon with 1 exteriorRing and 0 interiorRings
Multipoint 'MULTIPOINT (10 10, 20 20)' a MultiPoint with 2 points
MultiLineString 'MULTILINESTRING ((10 10, 20 20), (15 15, 30 15))' a MultiLineString with 2 linestrings
MultiPolygon 'MULTIPOLYGON ( ((10 10, 10 20, 20 20, 20 15, 10 10)), ((60 60, 70 70, 80 60, 60 60 ) ))' a MultiPolygon with 2 polygons
GeomCollection 'GEOMETRYCOLLECTION (POINT (10 10), POINT (30 30), LINESTRING (15 15, 20 20))' a GeometryCollection consisting of 2 Point values and a LineString value

Download the polyline geometry (in WKT format) of a street

Get the polyline geometry of a street, from a street ID, or a coordinate + radius/postal code.

REQUEST

Example:

&cmd=geoment&rqge=st&mo=37.767951111,-3.790683886&mocs=gdd&cs=4326&tolerance=0&stc=&pcode=23004&rad=500&buffer=

 

Where:

  • mo=Y,X (optional if &stc= is used)
  • mocs=gdd coordinate system used in &mo=
  • cs=4326 coordinate system used in data. Use 4326 for geographical system lat,long
  • tolerance= polyline simplification, in meters. If 0, returns the original data
  • stc= street code (optional if &mo= is used). This paramether have priority over &mo=
  • pcode= postal code (optional) -> if used, response includes only the street segments inside the postal code.
  • rad= radius (optional) -> if used, response includes only the street segments inside and intersected by radius. This paramether have priority over &pcode=. Use only with &mo=, not &stc=
  • buffer= returns a buffer around the street. Value in meters (optional).
