hello
thanks to everyone who has helped us out so far; the current view is that for point data, the osm-conflator and osm-conflator-audit tools are a good fit for syndicating government open data onto osm in a procedural way that can achieve community backing there's now a wiki page<https://wiki.openstreetmap.org/wiki/Import/London/Greater_London_Authority/Charging_Stations> that sets out the work to date, the data being imported and our implementation of an osm-conflator profile we've hit an impasse with osm-conflator-audit, being neither able to run a local installation due to issues with flask_oauthlib, nor (yet) host our changes file on audit.osmz.ru; consequently we may fall-back to using the josm file that osm-conflator outputs with reference to the changes file it also produces on geojson.io - there are a few instances where our data conflates with existing records so we'll proceed with caution; additionally, there's the question of how to show that some charging stations we're mapping are restricted to taxis, currently this is stored in a note tag. joe ________________________________ From: Nick Allen <nick.allen...@gmail.com> Sent: 14 March 2019 14:35:11 To: Joseph Leach Cc: Tom Chance; talk-gb-london@openstreetmap.org Subject: Re: [Talk-gb-london] bulk importing london open data to osm Hi Joe, Just in case you were wondering if Tom was the only one here. Welcome, and I look forward to seeing progress. I think Tom made a very good job of answering you, so I won't interfere and confuse things.

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.
