Just got back from 2-1/2 days on the road, during which inter alia I traversed the P-25 and part of the P-21 national highways in Turkmenistan. I collected roughly 38,000 ground-level images with Mapillary, but will delete some before uploading due to quality issues. Got good GPS traces, however. Tried using MAPS.ME to collect POIs but there are issues due to its limited universe of categories. I ended up using "Attraction" as a default tag just to mark POIs geographically (including U-turns on newly divided highways and such), and now am plowing through them at my desktop computer to correct them to something resembling reality and OSM guidelines. I hope this will not garner too much opprobrium from the OSM community. I'm cleaning up the mess I've created as quickly as I can, but I did want to collect data as I was traveling!
