    A collection of geospatial components and interfaces that implement different flavors of proximity search.

    A collection of geospatial components and interfaces that implement different flavors of proximity search.

    Note: com.here.platform.location packages use a set of terms to describe different geospatial aspects:

    Coordinates: Cartesian coordinates (x, y[, z]) Geo coordinates: WGS 84 coordinates (latitude, longitude[, elevation]) Point: Geometry element holding coordinates + system specific information (ID, precision, etc.) Geo point: Geospatial element holding geocoordinates + system specific information Node: Topological element of the road network representing a location where multiple manoeuvres are possible, such as before an intersection or where a lane starts/finishes forming/merging. Segment: Topological element of the road network that connects exactly two nodes Any change in attributes along the segment define a new link (sub-segment) Link: Nonbreakable element of a topological segment with a particular set of attributes Attribute: Property of a link, such as its speed limit Vertex: Node in the routing graph, referring to a topological segment Edge: Arc in the routing graph that connects exactly two vertices Incidence graph: Routing graph providing vertices connected to a given edge:

    • its source vertex, which is the tail of the arrow when directed
    • its target vertex, which is the head of the arrow when directed Directed graph: Incidence graph providing edges going out of a given vertex

    Note: WGS84-related functionality works with a reasonable accuracy when latitude is between -85 and +85 degrees.

class TiledProximitySearch extends ProximitySearch[(TileId, SegmentIndex)]

An implementation of com.here.platform.location.core.geospatial.ProximitySearch for the indexed segment geometry of the Optimized Map for Location Library, which uses an R-tree to find segments.

It will return one result for each segment chunk that is in range. Thus, the search might return multiple results for a segment.

See also GeometryTile for details on the data format used by this class.

  1. new TiledProximitySearch(tileById: (TileId) ⇒ Option[GeometryTile], tileResolver: DiskTileResolver, projection: GeoProjection)

    tileById

    Used to retrieve the necessary data for a search

    tileResolver

    Determines which tiles need to be looked at for a particular search

    projection

    Used for quickly calculating distances between points. Specifically, the distance between the search center and a segment chunk
