Composites

composite OSMPointMatcher(output Out0; input In0)

The OSMPointMapMatcher composite analyzes time based object location data to heuristically project points on a network of roads specified by an OpenStreetMaps XML map file. For each point, the mapped point is the best approximation of where on the path network the entity is likely to be, provided some constraints.This operator takes as input a set of locations reported by a moving object, perhaps through a GPS device. The information on known paths in the path network must be provided as input. This takes the form of a set of points or nodes and the paths (edges) between them.
