Layers

Buildings, like all catalogs in the HERE Map Layers collection, organizes map data by several versioned layers. This data specification provides information on the Buildings catalog which contains the Buildings layer.

A single catalog version number is assigned to the entire catalog. When HERE updates a catalog, its version number is incremented. Catalog layers and partitions can be retrieved by version while preserving consistency between all published content. This allows you to select and process only the data of interest, or to process only specific changes within a layer. For information on using versioned layers, see Layers in the Data User Guide.

Note

Some property definitions are of the generated anonymous type. For the purposes of readability, generated anonymous type property sets have been given titles based on the closest associated property within the documentation.

For example, chainsItems contains a set of generated anonymous type properties collectively referred to as chainsItems due to the set's relationship to the chains property (chainsItems from: chains + items).

Generated anonymous type property sets are introduced with text supplying the origin of the set's title, such as the following:

"Generated anonymous type: paymentCash from: payment + cash."

Buildings layer overview

The Buildings layer publishes geometry for the outline of the building, and includes other attributes relevant to the building, including naming. The Buildings layer also contains two-dimensional building footprints with their corresponding attributes, such as height and buildingType, representing man-made building structures.

Buildings layer usage

The Buildings layer can be used for:

  • Map display
  • Search
  • GIS analysis for city planning
  • Flood modeling (together with the Hydrography layer)
  • Navigation / situational awareness
  • Ride-share and delivery pick-up and drop-off points
  • Tactical planning for law enforcement and military
  • Obstacle avoidance for aviation takeoff procedures
