[OSM-talk] Identical Duplicate buildings

[Pierre Béland]

Hi Stephan,

good news that you can manage to fix this in the iD editor. Discussion about quality did not focus on the Editor tools.

OSMCha let observe changesets content. It did show more general quality problems then the duplicates. Discussion about the quality was  about the impact to promote Mapathons with insufficient support to groups and individuals and the necessity to develop Monitoring tools that let identify deficiencies and organize to correct them.

I think we spotted a bug in iD here. I recently fixed a lower two-digit 
number of duplicates which fit well into this pattern.
All duplicate the exact same geometry that the same user had uploaded a 
bit earlier. Just upload message did differ and on second upload 
additional objects had been touched.

Maybe some hickup during upload tricks iD into thinking they hadn't been 
uploaded yet.

I would generally agree that HOT edits are quite frequently of not so 
great quality, but this time it seems to more of an editor problem than 
HOT process.
