ImproveOSM is a suite of tools that exposes the results of a massive data analysis comparing huge amount of GPS data point with OpenStreetMap data and displays them in a way that makes it easy for anyone to improve the map with missing roads, turn restrictions and one-ways. The first version of the ImproveOSM plugin was released in 2015 September, since then we had improved our detections and added new features to the plugin. In this lighting talk we will present the plugin new features and how to use it effectively for mapping.
