Hello everyone,

This is Andrew again from Apple. I wanted to let everyone know that we just updated the MapRoulette challenges related to road network issues in Denmark with new OSM data. 

You can find the challenges in this MapRoulette project: https://maproulette.org/browse/projects/39285 and they include things like overly sharp road angles, roads that cross but aren’t connected, roads that aren’t connected to anything, overlapping roads, turn restrictions, roads that are close but not connected to others, and other similar issues. I plan to work on some of them myself too.

If you haven’t used it before, MapRoulette lets you go through potential issues in OSM data one by one and either correct them or indicate they are not a problem. The challenges were created with our Atlas data analysis tool: https://github.com/osmlab/atlas <https://github.com/osmlab/atlas>.

If you aren’t sure what challenge to try, sharp angles or crossing roads are probably the easiest but they should all be fairly straightforward.

Please let me know if you have any suggestions or feedback. Thank you! 

Andrew

(Some may be pedestrian, which is ok.)

We’ve been working on the a few road issues and buildings for some time (https://github.com/osmlab/appledata/issues/69 <https://github.com/osmlab/appledata/issues/69> and https://github.com/osmlab/appledata/issues/118 <https://github.com/osmlab/appledata/issues/118>) and recently used our Atlas data analysis tool (https://github.com/osmlab/atlas <https://github.com/osmlab/atlas>) to look for a few types of potential issues, such as roads with sharp angles and buildings that intersect roads. I posted the results of those checks on MapRoulette, a tool that lets you go through potential issues one by one and either correct them or indicate they are not a problem. I wanted to let you know they are available in case others wanted to try fixing some of them — I also plan to go through some of them myself.
