There has been a recent push to improve the coverage of exit numbers and destination signs on the motorways in the US by the data team at Mapbox. Some context here [1][2][3][4]. The primary sources of data were DoT documents and Mapillary images. The secondary source was Wikipedia, but as per the conversation with the local mappers, it is not a good idea to completely trust wikipedia documents for mapping the exit numbers and destinations. There are certain highways which do not have Mapillary coverage and it is difficult to validate/identify the missing exit numbers and destination. It will be a great help if local mappers can help share reliable sources and validate the existing data that will help improve the coverage of this data on the map
We been working on this from the beginning of April and reviewed more than 220 highways in 9 states. The goal would be to authenticate all the existing data and fill in the gaps using verifiable sources wherever possible. Here is the Overpass query to get a better sense of the stats: * Total motorway_junction edited by team in last two weeks: 179 [5] This is the detailed workflow for *Exit mapping* [6] and *Destination mapping* [7] that was used for this mapping activity. Would be great to hear your feedback on how it can be improved for further such tasks, please drop a comment on the *project tracker* [3] . I want to thank all of you in the community for giving feedback, calling us out on the occasional errors, and working with us to improve signpost mapping conventions. I feel proud to be a member of such a great mapping community!
