<blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">I'm pleased to be able to report that three councils have agreed to<br>
let us use their Definitive Statements of Public Rights of Way under<br>
the UK Open Government License (OGL). (I'll be posting the emails I<br>
sent to the councils and some other notes about the correspondence I<br>
had with them in a separate message for anyone who's interested.) The<br>
councils who've told me we can use their Definitive Statements under<br>
the OGL are:<br>
<br>
* Hertfordshire<br>
* Oxfordshire<br>
* Worcestershire<br>
<br>
The first two of these have the statements online in a convenient form<br>
[1], [2]. Worcestershire does not, but the text of each right of way<br>
is available from a link in the popup by clicking on the interactive<br>
map [3]. Accessing them in this way, it will be hard to avoid<br>
inadvertently making use of the additional information about the route<br>
of each way from the map. So I've obtained a list of all the image<br>
files, which I'm planning to use to allow direct access to the<br>
statements for each parish. Watch this space for more details, though<br>
first I have to chase up a few of the files that seem to be missing.<br>
<br>
The OGL requires attribution, so I've added details of these three<br>
counties to the appropriate wiki page [4]. (Unfortunately though, this<br>
page isn't obviously linked from the main OSM map or official<br>
copyright/license page [5] so I'm not convinced that attribution<br>
statements on [4] completely fulfil our obligations at the moment.<br>
Yes, we've provided attribution, but it's not somewhere that we could<br>
reasonably expect users to find it. I've been in touch with LWG about<br>
this, and fixing things is on their to do list -- though it seem from<br>
their minutes that this has been the case since September 2011. Does<br>
anyone know who is able to edit the text on [5]?)<br>
<br>
I'm hopeful that we'll be able to make use of the statements to verify<br>
the designation of already mapped ways, and add the appropriate<br>
designation tag where it's missing. In most cases, the description<br>
probably won't be enough to be able to map a way without a survey.<br>
However in conjunction with aerial imagery and maybe a bit of local<br>
knowledge, it may be possible to do so for some routes. But the<br>
statements will certainly be helpful in any effort of complete the<br>
mapping of public rights of way by identifying missing routes in need<br>
of a survey.<br>
<br>
To help with matching routes up and checking off what has been found,<br>
it will be useful to tag the ways with the Council's reference number,<br>
using our ref=* key. Doing so has been discussed on this list before<br>
[6]. (Though following some more recent discussion [7] we may be<br>
heading towards using prow:ref=* instead to avoid a clash with other<br>
uses of ref on the same ways.) In the thread at [6] it's been observed<br>
that different councils use different path numbering schemes, so we'll<br>
probably be unable to use a common scheme across the whole country.<br>
Looking at the numbering scheme used by the three councils above, I'd<br>
suggest the following ref formats:<br>
<br>
* Hertfordshire: "[Parish] [0Num]"<br>
* Oxfordshire: "[Pn]/[Num]"<br>
* Worcestershire: "[PC]-[0Num]"<br>
<br>
where [Parish] is the full parish name (in Title case), [Pn] is a<br>
numerical parish code, [PC] is a two letter parish code (with<br>
upper-case letters), [Num] is the numerical path number without<br>
leading zeros, and [0Num] is the numerical path number with leading<br>
zeros.<br>
<br>
(Note that Worcestershire has re-numbered all their paths, giving each<br>
segment between path junctions a distinct number within the parish.<br>
The definitive statements still use the old numbers in the route<br>
descriptions, and it might not be possible to tell which segment of<br>
each route has which new number. It it probably a good idea to store<br>
the original reference numbers in OSM too, eg with old_ref="[Parish]<br>
[Num]" top make using the definitive statements easier.)<br>
<br>
Finally, when tagging ways with designation=* and/or ref=* based on<br>
the definitive statements, I think it would be useful to indicate the<br>
source. I'd suggest using source:designation=definitive_statement<br>
and/or source:ref=definitive_statement as appropriate.<br>
<br>
