What Is the Geofencing Extension API?
The HERE Geofencing Extension API is a REST API that allows you to track whether or not mobile assets are located within the specified geographic areas. An asset is any kind of trackable object, such as a person, car, smartphone, or delivery package.
You can define the geographic areas as geometries in the form of geographic polygons, polylines, or points that are relevant for these assets. You can also choose to check the assets' position against Map layers, for example, postal code boundaries or census boundary layers.
