Customize maps with compact overlay encoding
The HERE Map Image API v3 offers a compact style encoding option, which lets you overlay additional data onto your map images more efficiently than the GeoJSON format. Despite its compactness, it supports the same geometry types and style properties as GeoJSON, ensuring the output remains identical.
In this interactive example, you can define up to three distinct geometry instances to overlay onto the map image though the overlay parameter. The API request is preconfigured to automatically adjust the map position so that the image captures every overlay feature.
As a staritng point, this example contains sample Point, Line, and Polygon instances for you to examine and adjust. You can also provide your own samples.

In addition, you have an option to change the map style as well as to specify the space around each overlay feature through the optional padding parameter.
