HERE Interactive Map Layer: Spatial and Property Search
Features stored in interactive map layers can be retrieved by spatial and/or property search queries. The spatial search query can be used to retrieve features that intersect a given point, line or area. This is provided to the API as a GeoJSON geometry. Additionally, a radius parameter defined in meters could be specified.
The property search query can be used to retrieve features that have a property value that matches a given value. It is possible to search for numeric ranges, to query multiple property values, and to combine the queries using logical operators. Property search can be combined with requests for tile, bounding box and spatial search.
This example includes a map to explore sport facilities in the city of Amsterdam. Amsterdam manages 26 sports parks, 19 sports centres, 10 swimming pools and over 100 smaller sports facilities in various neighbourhoods.
Property search is used to filter the features by the type of sport. The locations of the facilities are combined as a multipoint geometry. This geometry then used as an input for the spatial search query to find the administrative areas that contain the facilities of that type.
