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.
See it in action now!
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.
