Hi everyone, Another round of updates on LABuildings import. Last week we've imported ~1.1M buildings in LA City. Over 100 usernames participated. We are close to finishing Phase 1 (LA City) and will continue data QA and cleanup if needed.
We've posted OSM diaries on the process: - On tools we built: https://www.openstreetmap.org/user/manings/diary/38969 - On the data: https://www.openstreetmap.org/user/manings/diary/39081 As always comments, from the community is appreciated. - Github - https://github.com/osmlab/labuildings/issues/ - Chat - https://gitter.im/osmlab/labuildings - Wiki - https://wiki.openstreetmap.org/wiki/Los_angeles,_California/Buildings_Import On Thu, May 5, 2016 at 8:07 PM, maning sambale <emmanuel.samb...@gmail.com> wrote: > Hi, > > Over the past month, since we started the LA building import [0], > ~330K buildings were added by 74 different users [1].
