HERE platform catalogs contain layers with location data that is mostly partitioned geographically. The Data Inspector Library allows rendering Protobuf-encoded, geographically partitioned data on top of the basemap with the help of custom GeoJSON rendering plugins.
The Data Inspector Library uses Protocol Buffers (schemas) to decode these partitions. A partition is rendered with a plugin that is invoked once the partition is decoded. The rendering plugin returns the GeoJSON representation of the partition that is then rendered by the
GeoJsonDataSource. The Platform lets you attach a GeoJSON plugin to your schema.
For a full list of GeoJSON features supported by the Data Inspector Library, see Preconditions for Visualization.
Locally by installing the Web App Generator with the option
renderer.plugin.template.jsfile that becomes available in the generated example application. For more information, see the Custom Data chapter.
