OSMTime – Adding missing roundabouts using MapRoulette

At our next event we will improve OpenStreetMap by adding missing roundabouts via MapRoulette.

Bogdan Gliga will be our guest speaker for the evening – he will talk about how we identified missing roundabouts based on GPS probe data and OSM geometries.

MapRoulette (http://maproulette.org/) is a fun way to fix missing roundabouts in OpenStreetMap. In MapRoutelle one solves map tasks - where one task equals a potential problem in OpenStreetMap - one looks at this challenges and provides a "resolution" (fix it, not a problem, or skips the challenge).

Requirements:

· As the event will be focused mostly on editing, please bring a laptop and charger

· (optional) JOSM installed on your laptop.
