attending the meetup sounds like a very good idea
on the bus stop example, corporate data releases can have inaccuracies ... at this point i should note that i copied a drinking fountain<https://www.onelessbottle.org/fountainfund/> dataset to sixteen amenities<https://overpass-turbo.eu/s/GVJ> (and added metadata to one in bexleyheath), looking back, adding notes rather than features may have been better in relation to the need for surveys will now go and check the guys hospital one<https://www.openstreetmap.org/node/6334493761> during lunch ________________________________ From: Tom Chance <t...@acrewoods.net> Sent: 14 March 2019 12:12:47 To: Joseph Leach Cc: talk-gb-london@openstreetmap.org Subject: Re: [Talk-gb-london] bulk importing london open data to osm Hi Joe, There's further useful guidance on the wiki, inc on the licensing point: https://wiki.openstreetmap.org/wiki/Import/Guidelines There's also a regular pub meet-up where you'll find people more up to date and knowledgeable than me! The next is on Thurs 28th: https://wiki.openstreetmap.org/wiki/London One thing they might have thoughts on is how to involve the wider OSM London community, for example in checking and cleaning data that can be imported, or manually adding data. I recall one import many years ago of TfL bus stop data, where we then had to go through removing lots of duplicates, and quite often we found that the TfL data was less accurate than existing OSM data! So it was worth checking each one with a survey.

Welcome to the list. I used to work at the GLA (2009-16) and am glad to see you proposing this. Others will have a better idea of the process, but I'd think a first step would be to create a wiki page and set out the datasets you have, indicating for each one any licensing conditions/issues, what fields you'd import and a check on the current data already existing. On the latter point, for example, there are already quite a few charging stations mapped (https://overpass-turbo.eu/s/GVx) and we wouldn't want to duplicate those with your import. You can either go through them one by one, deleting duplicates from your dataset before importing (or merging data to add new fields), or stick the dataset up and invite people to manually check and copy across each charging station.
