Hi All, I found the combo of overpass and qGIS was a really good combo specifically for this sort of thing. Then you could export into R if you wanted to run stats (qGIS has a pretty good stats engine too) All you'd have to enter is the building tag as a search, and it'll return the results.
The web interface would be even faster for a non-GIS-er and you could dump it all into a nice .CSV. There's a few quick tutorials under 10 minutes that should get ya up to speed. https://vimeo.com/189554102 https://wiki.openstreetmap.org/wiki/Overpass_turbo and I'm by no means a "Ph. D " in OSM :) Happy Mapping, Keith On Thu, Sep 13, 2018 at 7:01 AM <talk-ca-requ...@openstreetmap.org> wrote: > Send Talk-ca mailing list submissions to > talk-ca@openstreetmap.org > > To subscribe or unsubscribe via the World Wide Web, visit > https://lists.openstreetmap.org/listinfo/talk-ca > or, via email, send a message with subject or body 'help' to > talk-ca-requ...@openstreetmap.org > > You can reach the person managing the list at > talk-ca-ow...@openstreetmap.org > > When replying, please edit your Subject line so it is more specific > than "Re: Contents of Talk-ca digest..." > > > Today's Topics: > > 1. counting buildings - ( 2020 project ) - help please.
