How to Improve OpenStreetMap Road Data with Mapillary

How to Improve OpenStreetMap Road Data with Mapillary

After seeing the diary of how to use Mapillary to add building attributes on the state of San Francisco buildings, I decided to create this article on how to use Mapillary as a tool to improve OSM road data. This article will focus on how to use Mapillary traffic sign detection to implement turn restrictions, and Mapillary imagery to add lane value and turning lanes. I won’t get into how to capture Mapillary images using smartphones or action cams, as you can find that information on the Mapillary website and you can request a car or bike mount for your smartphone to facilitate capturing.

(Please note that from my experience, after uploading the photos to Mapillary, the traffic sign detection can take from 24 to 96 hours to be processed and being displayed on the map.)
