Re: [Talk-GB] Govt should pressure Google to release data
Hi Gregory, Leigh has expanded a bit on twitter: https://twitter.com/ldodds/status/1066233917722845184 I think their argument is that some big tech companies are already sharing back (e.g. into OSM) and this should be seen as the standard approach. This becomes particularly true when big tech has used crowd sourcing to build their data for free. It is also an aspiration to avoid duplication of work so that we get to the stage where we unlock the benefits of geospatial data sooner (they're thinking autonomous vehicles, etc). Problem is that there is potential to commercialise data here. So first steps could be releasing data where the commercial value is low yet there is still a public benefit. I think ODI are true to their strategy: advocate greater availability of open data for public good by asking big tech not to hoard data that can be released - starting with data of low commercial value but high public value. Data on wheelchair accessibility is given as an example. Best regards, *Rob* ___ Talk-GB mailing list Talk-GB@openstreetmap.org https://lists.openstreetmap.org/listinfo/talk-gb
Re: [Talk-GB] How to map houses
Hi BD, Ed's right that opinions will vary and there's often not one perfect answer. Allow me to propose a modification of Martin's suggestion, for the case where you have one single outline for a whole terrace and no knowledge of exactly which housenumber sits where: building=terrace addr:housenumer=5-17 addr:interpolation=2 addr:street=Westbury Avenue Using address interpolation on an outline is not that common, I admit, but it does at least mean the data is there in machine-readable format, i.e. it's relatively straightforward to write an automatic query to know where to send someone if they're looking for 7 Westbury Avenue. The more orthodox use is described here: https://wiki.openstreetmap.org/wiki/Addresses#Using_interpolation where, assuming you know which end of the row is number 5 and which is number 17, you'd use building=terrace and then create a separate way (typically not even connected to the building outline) that holds the addresses and interpolation as shown in the little diagram you see on that wiki page.

Which one should we consider the most appropriate way to map longer building comprised of few properties? There is a basic principle that every change should improve the map. As such, an outline for the terrace, with points for the houses, is better than just points, or just the building, but is not as good as mapping the footprint of every house. Any of these is better than mapping nothing at all. A simple address interpolation is also better than nothing at all. It comes down to how much effort you want to expend, and how accurately you can actually determine the geometry. ___ Talk-GB mailing list Talk-GB@openstreetmap.org https://lists.openstreetmap.org/listinfo/talk-gb

BD asked: > can some one tell me, what is the best way to map houses in residential area. > > Which one should we consider the most appropriate way to map longer building > comprised of few properties? I'm not sure either of your two examples are the best way, and I suspect the answer is likely to be "opinions vary". Your example of individual houses would, in my opinion, be the better of the two if it had house numbers. The long buildings with nodes to mark house numbers are better than nothing. Buildings with no other information than just an outline are nothing but visual clutter which makes it harder to see where still needs address surveying without zooming in close (I'm sure my opinion will upset a lot of people who spend ages sitting there tracing them, but when I've come to add house numbers in the past it is often easier to delete the building outlines and start again). Here are some other examples you might like to look at. Maldon, Essex https://osm.org/go/0EFrpAyFq?m= Being picky, I think the individual property boundaries are perhaps a bit over the top, but if they are going to be added then there probably needs to be access to the house from the street rather than a solid barrier. Sutton Coldfield, Birmingham https://osm.org/go/euzN_rS4l--?m= Nottingham https://osm.org/go/eu8bMaoJB-- East Dulwich https://osm.org/go/euuuXeO_c-- Clacton-on-Sea https://osm.org/go/0EHmQd7ib Apart from the last I just picked places at random and zoomed in. The level of detail varies, but what seems to be common is the individual outlines with an address on each. I hope this helps, Ed ___ Talk-GB mailing list Talk-GB@openstreetmap.org https://lists.openstreetmap.org/listinfo/talk-gb

Open data at Ordnance Survey is also getting better (I thought we/ODI we focusing on improving that, we all know govt could do better). I think it's badly headlined, and badly reported. If you read the ODI's actual submission to the consultation, what they are actually calling for is for government agencies and contractors to release more data under OGL or compatible licences. In particular, things like USRNs, UPRNs, TOIDs, INSPIRE IDs, etc. The ODI's argument is that the lack of open data makes it difficult, if not impossible, for start-ups and other SMEs to compete with the giants (such as Google and Apple), as they do not have the resources to generate their own geospatial data and both the costs and conditions of licensing non-free data makes it impractical for them to use. I entirely agree with that, and I would hope that the OSM community does, too. Mark ___ Talk-GB mailing list Talk-GB@openstreetmap.org https://lists.openstreetmap.org/listinfo/talk-gb

Open data at Ordnance Survey is also getting better (I thought we/ODI we focusing on improving that, we all know govt could do better). Mapping data = user data, like current traffic locations or insights into journeys people take? This would be amazing to get. But the companies won't give it away if you ask nicely, it's potentially their most valuable asset besides giving away the actual users. The govt can't control that, unless it was part of an existing agreement (i.e. bike share schemes, or taxis). The article/press release disappoints me, it feels like a waste of media attention. It possibly even dilutes the other messages of the ODI and it's founders.
