HERE Map Content Schema

Layers

The HERE Map Content catalog organizes map data by several versioned layers. A single catalog version number is assigned to the entire catalog. When HERE updates the 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 theData User Guide

The layers in the HERE Map Content catalog can be thematically grouped as follows:

  • Roads layers
  • Lanes layers
  • Places layers
  • Buildings layers
  • Cartography layers
  • Administrative Areas layers
  • Rules & Regulations layers
  • Addressing & Postal layers
  • Visuals map-references layers
The figure below illustrates the logical relationship among these layers.
Figure 1. Overview of the Logical Relationship Among the Layers

The following sections provide a logical diagram and a table summarizing the layers for each layer group in the HERE Map Content catalog.
