[Talk-GB] State of the map Scotland - Speakers and Sponsors

[Bob Kerr]

Hi,

This years State of the map Scotland is a slightly different affair than last 
years due to a larger venue.

We are splitting both days into two, morning and afternoon. In the afternoon we 
are requesting speakers from other GIS or professional organisations to come in 
and speak about their work with maps. These talks do not have to be about 
Openstreetmap or free data but it would be good if there was some connection. 
This will allow us to use the conference as a meeting of minds between 
volunteer mappers and professional groups. We have 16 30 minute slots available 
in the two days and two conference rooms. This will be the formal side of the 
conference, The mornings will be reserved for Openstreetmappers in the non 
conference format.

Details of the Conference here

http://wiki.openstreetmap.org/wiki/State_Of_The_Map_Scotland_2012


If anyone knows of any groups that would like to speak please let me know.

We are also looking for some small sponsorship to pay for Edinburgh University 
Staff who are needed to let us in.

Cheers

Re: [Talk-GB] Hadrian's Wall

[Dudley Ibbett]

Hi

I'm trying to do a bit of mapping near Once Brewed following a walk this 
weekend.  Hadrian's Wall seems to be tagged as "historic=ruins, name=..." at 
one point and "historic=wall, name=..." at another.   The former seems to be 
trying to create an area in JOSM.

Given that I am trying to add barriers.  i.e. walls, fences, gates, stiles etc 
it would seem that where Hadrian's Wall is actually a physical barrier it 
should have the tag.  i.e. "barrier=wall" and "historic=wall".  I note that the 
documentation for "historic" suggests that "historic=yes" should be avoided.

I assume that Hadrian's Wall has been mapped as a historic "wall" whether it 
still exists as a barrier or not.  Does anyone know the source of the wall data 
 (there is no tag in the section where I am mapping) as having walked the path 
that is directly to the side of the wall some of what is currently mapped seems 
to need adjustment?  Bing appears to be reasonably accurate when compared to 
the my own and others GPS data in this area.

Many Thanks

Dudley

Re: [Talk-GB] Southwest Coast Path (relation) has mostly disappeared.

It's taken me several months but the South West Coast Path is now stored as
a super-relation. I'd delayed completing it until the licence change
process had finished. Initially wasn't sure about how may relations I
should split it into to, but I decided to use the 52 sections used by
official website. I've updated the couple of wiki pages pointing to the
route, and created a separate page for the relation
[link
]

All the appropriate tags for the relation (eg type=route) are attached to
the super-relation. I've only added a name, url, and note tag to the
sections. This was because I was unsure if adding a tag such as type=route
to a section made the section a distinct and separate hiking route. A
website that shows hiking routes
[link]
states it assumes a child relation is simply a section of the parent
relation if they both have the same Network tag. This suggests I should add
all the route tags to the individual sections. I can add them fairly
quickly if they are needed

I've left the old relation in the "database" without route tags in case I
have somehow blundered and there is a need to restore the old version. If
there's no problems I'll delete the old relation in a few days.

Cheers,
jason

[Talk-GB] UK Postcodes - Potential data source

[Rob Nickerson]

Hi All,

Please correct me if I am wrong, but to the best of my understanding we are
still struggling to find a good source of postcode data under an open
licence. From what I understand the CodePoint data set is currently seen as
not available for use in OSM.

That is where this data set available under the OGL licence may help:
http://www.landregistry.gov.uk/public/information/public-data/price-paid-data

It's not perfect as it does not provide lat/lon co-ordinates, but it does
include full addresses for residential properties sold within each month.
This means that it gives us a link between address (something we can
survey) and postcode (which we can't easily survey). It also states which
properties are new (i.e. new builds, new addresses). Any thoughts?

If this is a useful source I was thinking a simple database where we can
look up an address and find a postcode for adding to OSM. Going one step
further we could try to find automatic matches between OSM addresses and
this dataset and therefore generate a list of postcodes that could be
suitable for import. I guess for someone with experience this would be
quite an do-able hack?

Regards,
Rob

Re: [Talk-GB] UK Postcodes - Potential data source

[Shaun McDonald]

Hi Rob,

Postcodes are a bit more complicated. Postcodes are a series of points, not a 
single point, as based on CodePoint data. I would not like to see a raw import 
of the CodePoint Open data as it is just the centroids of the postcodes, 
instead the postcodes need to be attached to specific addresses, which is more 
work, though more accurate and what is needed by the geocoders.

There are websites out there such as CycleStreets that are successfully using 
the CodePoint Open data for geocoding in addition to other OSM data.

> "instead the postcodes need to be attached to specific addresses"

That's what I posted in the Land Reg link. :-)
Rob

p.s. What I have in my mind is to grab each months data release from land
registry (thus building up a good database of address + postcode), and then
have some tool to visualise where we can match OSM addresses (without
postcode) to these land reg addresses (with postcode). I could code a
database but my tech skills don't go much beyond that :-(
