<html><body><div style="color:#000; background-color:#fff; font-family:times new roman, new york, times, serif;font-size:12pt"><div><span>Hi,</span></div><div><span><br></span></div><div><span>In Edinburgh the list of public roads is available here</span></div><div><span><br></span></div><div>http://www.edinburgh.gov.uk/info/177/register_of_public_roads/865/public_roads_in_edinburgh<br></div><div><br></div><div>The reason that I refer to this is that the Data from OS is not as accurate or up to date as this data. There is also some roads that are not named. I know from experience that the OS data is not fully correct and neither is OSM data. However as we are correcting the roads in edinburgh, this gets filtered back to OS which in turn goes to ITO and eventually we will all have the same correct data, It will take some time. We also have very few surveyors.</div><div><br></div><div>My point though is that we do have some data available from the council,
and if we can create a heat map that shows which councils are releasing data then it may encourage others to do the same. My question is would it be worthwhile doing.</div><div><br></div><div>Cheers</div><div><br></div><div>bob</div><div><br></div><div style="font-size: 12pt; font-family: 'times new roman', 'new york', times, serif; "><div style="font-size: 12pt; font-family: 'times new roman', 'new york', times, serif; "><font size="2" face="Arial"><hr size="1"><b><span style="font-weight:bold;">From:</span></b> Richard Fairhurst <richard@systemeD.net><br><b><span style="font-weight: bold;">To:</span></b> talk-gb@openstreetmap.org<br><b><span style="font-weight: bold;">Sent:</span></b> Tuesday, 7 June 2011, 14:37<br><b><span style="font-weight: bold;">Subject:</span></b> Re: [Talk-GB] OpenKent, OSM coverage estimation<br></font><br>TimSC wrote:<br>> I think you miss my point.

Glad you've stopped. :)<br><br>> [...]<br>> Any what if the government dataset is open and stomps on OSM's attempt?<br><br>OS OpenData is easily the best free geodata available in the UK and I've<br>just used it (in preference to OSM) to make a lovely paper map, but it<br>hasn't killed OSM yet. :)<br><br>> (Don't bother saying "improve OSM" because that IS the approach we use<br>> and still the government set is better, in some cases.) Duplicating<br>> other open
data sets seems a waste of time - as you seem to imply by<br>> resurveying stuff already available elsewhere.<br><br>In a few cases, manually importing data can indeed be a useful tool. The<br>high-resolution rivers and streams in VectorMap District are quite useful<br>_if_ you know the stream is indeed there, which obviously VMD doesn't tell<br>you. It's not really any better than using a combination of aerial imagery<br>and your own knowledge, but it can be useful, yes.<br><br>But this is pretty much only true where the data is impractical to survey<br>yourself. The canonical example is: if you import a town's roads, you get<br>a town's roads. If you survey a town's roads, you get a town's roads,<br>footpaths, cycle routes, pubs, etc. etc. I'm sure there's been an example<br>where an import has been significant in the success of OSM in the UK but<br>I'm struggling to think of one. Maybe someone else can help?<br><br>> I am not advocating
we<br>> only import data either. A hybrid approach - import AND crowd source -<br>> is better. If you want crowd sourced surveying only, I suggest you start<br>> another project.<br><br>Fortunately, I _like_ the licence that 23135 people have said they'll move<br>their data to, and only 387 have said they won't (that's 98.4% vs 1.6%).<br>So I'm not planning to be one of the people moving to another project. :)<br><br>cheers<br>Richard<br><br><br><br><br>_______________________________________________<br>Talk-GB mailing list<br><a ymailto="mailto:Talk-GB@openstreetmap.org" href="mailto:Talk-GB@openstreetmap.org">Talk-GB@openstreetmap.org</a><br><a href="http://lists.openstreetmap.org/listinfo/talk-gb" target="_blank">http://lists.openstreetmap.org/listinfo/talk-gb</a><br><br><br></div></div></div></body></html>
