I don't, no. I do still see people adding osm:* tags to their photos though, via the RSS feeds, but realistically I don't expect its gotten much traction. Like the blog post said it's still pretty a "dorky" feature and that means it really needs some love and tools and examples to help people

The stable ID question to me comes down to philosophy: It would be nice if the world was stable but it's not. Asking for stable IDs is like asking for the world not to change. But it does, continuously. Any road changes over time in name, surface, connectivity and it's other attributes. Perhap

[OSM-talk] Keepright batch tagging?

2011-08-01 Thread Nathan Edgars II
Is there any way to tag a bunch of 'errors' as false positives in one action? I ask because there are a number of "motorways without ref" such as http://keepright.ipax.at/report_map.php?zoom=13&lat=35.15338&lon=-89.92892&layers=B00T&ch=0%2C90&show_ign=0&show_tmpign=0 that shouldn't have refs.
