Optimized Map for Analytics Data Specification

Differences between OMA and HERE Map Content

  • HERE Map Content is a highly structured data model, with complex relationships (segment anchors, segment indexes)
  • OMA is a flat representation using simple relationships (global foreign keys, primary keys) supporting natural filters and joins across attributes/layers
  • OMA uses the GeoJSON format to represent geometries (points, segments, polygons)
  • OMA contains a subset of HERE Map Content. Currently, OMA includes the following layers of HERE Map Content catalog:
    • Road Topology and Geometry Layer
    • Road Attributes Layer
    • Navigation Attributes Layer
    • ADAS Attributes Layer
    • Other layers will be prioritized based on customer feedback and demand.
