OK, done for now. The size and relative arrangement of the buildings
is approximate

There's something very odd with the numbering between 15 and 27 Lake
View Drive (the houses fronting George Road), if someone can check
that.

The stream in the adjacent cutting also needs further survey - where
does it rise, and end?

Thank you. I managed to get down there today. I've added the roads and
some infrastructure; I also picked up a sales brochure showing the
planned layout, and took notes of the few house numbers already
allocated, some of which I'll add later tonight or tomorrow.

It's still only half built; with occupied houses nearer George Road
and holes in the ground at the far end.

The Potlatch2 stuff doesn't deal with the GML at all. What we're being
given, separately from this GML, is a converted version of the
dataset, and from the correspondence that I have it's going to be
released under the OGL. For the dataset that I'm dealing with, there's
no question whether there will be some bits not suitable for inclusion
in OSM - that would somewhat defeat the point!

As for the potlatch 2 code, it's worth clarifying that both the
merging code (in potlatch2) and the serverside code for accessing it
per-bbox [1] only deals with OSM format data, not GML. The work for
converting it from GML into .osm is contracted to the people who
actually understand the GML representation! It was done this way to
ensure that everything I've put into potlatch 2 is entirely generic
and reusable for any other datasets we wish to merge in the future.

Right. The actual actual data has eastings and northings. The excel
spreadsheet the telegraph links to doesn't. And it appears to me that
the telegraph's Google map is made from the spreadsheet, using
geocoded addresses rather than the actual eastings and northings.

I'll shut up on this now!

I've just been looking at the cycle data. While the dataset is
licenced as OGL (or as the metadata says "Crown Copyright with
data.gov.uk rights", if that is the same) I notice each record has
an allowedUse element which in the bits I've looked at are
"Commercial Licence" or "Not For Profit" - are those latter records
still OK for OSM use, or do the Potlatch 2 changes you've worked on
filter them out? I'll confess I've not looked in detail at what
items are covered by what, but it looks to be that their community
provided data is not for profit use in general, whereas the
professionally surveyed stuff allows commercial use.

Not that I'm aware of. From the ones I've seen so far, the geocoding
isn't exactly great for them, so I suspect they've been geocoded using
the address or postcode.

Thankfully the cycling data is a lot more professional than that, and
thankfully we won't need to unpick the GML that it comes in!

Is anyone looking at the car parks data in a similar method to the

I've used "commemoration" on a couple of memorial benches in my

now you mention it, "inscription" sounds more generic, as there might

I've certainly used "inscription" when mapping Swedish rune stones ...

[Talk-GB] New datasets being released by the DfT

2011-10-25 Thread Andy Allan 
Some of you might have seen mention of new datasets being released
(today, apparently, but I can't find them yet) by the DfT

http://www.telegraph.co.uk/motoring/news/8844733/Publishing-road-works-cycle-routes-and-car-parking-data-will-finally-get-Britain-moving.html

Obviously my main interest is in the cycling infrastructure data, but
I can see car parking being useful for OSM too. I've only been
involved with the cycling data.

For once, there's actually been a lot of planning behind-the-scenes on
how to make this data as useful as possible, including which steps
would make it more useful to combine into OSM - to me, clearly the
best way to keep the data up-to-date in the long term. That's a big
step forward from the "throw it over the wall" approach of most
government open-data releases, and I hope appropriate credit goes to
the right people when it's all finally fully public.

I've been working on some features in Potlatch 2 so that we can
inspect, consider and merge the cycling data attributes into OSM on a
street-by-street basis. Cyclestreets made a blog post about this
yesterday, including some screenshots. I'm working on setting up a
demonstration so that we can get feedback on both the data and the new
p2 features.

http://www.cyclestreets.net/blog/2011/10/24/osm-merging-tool/

Until then, this is just a heads-up to say we don't need to worry
about either bulk-importing the cycling data (boo, hiss etc), nor
about converting it from whatever format it is published on
data.gov.uk in, since converting it to a useful OSM-based format,
unencumbered by OS toids etc, is already being done. Also, it's a
heads-up to say I might be asking for volunteers soon to start picking
though the dataset and using it to improve the detail of our cycling
information.

If anyone has any questions, I'll do my best to answer!

Andy
