Vector Tiles API

The Vector Tiles endpoint provides geographic map data as squared sections called vector tiles, presented in a vector format.

  1. Each tile contains predefined collections of map features, such as points, lines, road shapes, water polygons, and building footprints, delivered in the specified vector formats.
  2. The tile's format is defined using the protobuf schema.
  3. Each tile layer's content and meaning are detailed in the tile layers description.

To get the vector map tile data use the following endpoint:
