In Streams 4.0.1, the Geospatial Toolkit included a new PointMapMatcher operator.  This operator maps raw incoming GPS locations to a point on the closest road in the road network.  While the concept of map matching may be simple, there are many interesting problems and challenges to solve, before we can accurately determine which road an entity is travelling on.  This article describes some of these unique challenges:  Real-time Map Matching in Streams v4.0.1.

In this video, Chris Recoskie describes some very interesting use cases related to real-time map matching.  He will also touch on some of the challenges and show you a demo of the PointMapMatcher.
