Hi, Ben and I have been working on "the road completion" project for quite some time now. The idea is to build a toolchain that harvests any open data source on road networks, and turn it into a list of "possibly missing roads in OSM".
For a project overview, look here: http://www.osm.be/2017/01/06/en-project-road-completion.html Because it should be scalable and easy to adapt, we started with very simple analysis methods. The idea is to make something simple that is quick to set up and easy to extend. The repository is on Github [1] We started of with Wegenregister, an extensive road dataset for Flanders. A first selection uses only roads that should be easy to map with just GRB and aerial imagery. Because feedback is essential (to correct the many mistakes in the source data, to fine-tune our processes, to avoid having a road seem missing until someone uncritically adds it), we are using Maproulette to coordinate task completion. Instructions are available on the wiki [2] We're presenting this project at the Informatie Vlaanderen Trefdag. It's a big thing that we got ourselves invited there at all! [3] If you want to help, start the task, have a look at the Github, improve the documentation, find another dataset to use, etc! 1: https://github.com/osmbe/road-completion 2: https://wiki.openstreetmap.org/wiki/WikiProject_Belgium/Road_completion_project/Instructions 3: https://overheid.vlaanderen.be/trefdag-informatie-vlaanderen -- Joost Schouppe
