Enhanced 3D City Models

Enhanced 3D City Models is content generated from attributes in the NAVTEQ map to represent visual aspects of a city including road surfaces, sidewalks and land use features to detailed, textured representations of buildings. Enhanced 3D City Models enables applications to create an immersive 3D navigable experience that helps drivers and pedestrians more easily orient themselves in unfamiliar or complex situations.

Data Features

  • Enhanced 3D City Models includes visual representations of the following:
    • Textured 2 dimensional polygons describing the footprint of a building with basic rooftop shape and a height attribute defining height of building
    • Realistic representation of roads, including dividers, lane markings, bridges and tunnels
    • Textured land use visualizations (such as rivers and parks)
    • All elements of the city visualization are created from, and referenced to, the NA VTEQ map – updates to the core map are automatically reflected in quarterly updates of the Enhanced 3D City Models

Format

  • Available in Collada (DAE) linked to NAVTEQ formats: GDF, SIF+, RDF and NAVSTREETS
