HERE Map Content Developer's Guide

Rendering with the GeoJSON Plugin

The HERE Map Content catalog comes with a set of fully customizable GeoJSON conversion scripts for rendering layers that use the HERE Tile partitioning scheme. See Layers to find out which layers use HERE Tile partitioning. The scripts create a defaulted view of the feature published, or referenced, by the applicable layer and its associated attributes.

The GeoJSON conversion scripts provided with the schema files only process the main feature attributes (such as identifier, anchor details, name, and category) plus a limited number set of attributes. However, you can modify the scripts to suit your needs. For example, you can:

  • Add additional attributes to the properties
  • Change the style
  • Apply aggregation

For more information about rendering HERE Map Content data with the GeoJSON plugin, see the Data Inspector Library Developer Guide.


Here are some examples of map renderings using the GeoJSON plugin.

Figure 1. ADAS Attributes Layer

This example shows a GeoJSON FeatureCollection created from the curvature values published by the Roads - ADAS Attributes layer. An attempt is made to distinguish sharp and vehicle turns from other ones, requiring driver attention.

Figure 2. Advanced Navigation Attributes

The example below shows as GeoJSON FeatureCollection created from the traffic sign locations and types published by the Roads - Advanced Navigation Attributes layer. It leverages the ability to associate a symbol map to a collection in SVG format.

Figure 3. Places - All Categories

The example below shows as GeoJSON FeatureCollection created from the confidence values published by the Places - All categories layer. Besides conditional styling, the example shows the name of each selected place as well as its primary and secondary category. A HERE MapCreator link is added to report any feedback directly into the HERE platform.

Figure 4. Postal Area Boundaries

The example below shows a GeoJSON FeatureCollection created from selected boundaries in the Addressing - Postal Area Boundaries layer. The colors are set randomly.
