package geospatial

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.
