Cadastral Parcel ID Generator
An open Application Programming Interface (API) service providing a list of cadastral parcel ID. It gets geometric data from the client and returns a list of intersecting cadastral parcels ID list, including their cadastral parcel IDs, zone status, and settlement name.
What is it used for?
The API is designed to return the cadastral parcel ID list within a client-specified area, returning results in the Hungarian projection system (EOV). The service can be accessed via an HTTP GET request. The geometry can be provided as a request parameter in GeoJSON format.
The service processes only requests containing geometries within the predefined size limits:
- A single geometry may be specified per request. The geometry type may be Point, LineString, or Polygon.
- The geometry may contain a maximum of 80 vertices.
- The length of a LineString must be less than 1 km.
- The area of a Polygon must be less than 1 km², and its perimeter must not exceed 20 km.
- Polygons with holes are not permitted.
- The maximum number of parcels that can be queried simultaneously is 500.
Who is it recommended for?
For anyone whose activities require cadastral parcel IDs (from land registry data) and who wants to know which IDs intersects with their own geometry.
