There seems to be an error in one of the 0.5 API DTD's. The full-DTD-page says that a relation may have 0 or more tags or members, while the actual DTD on http://dev.openstreetmap.org/~kleptog/osm-0.5.dtd says that there should be at least one tag or member. I suppose that the former option is true if I read through other explanations.

So, if someone can confirm this, this can be cleaned up before version 0.6 maybe :).

Kind regards,

Michel

After being an 'in principle' supporter of OSM for some time now I finally got of my lazy behind and GPS traced all the streets in my local suburb of Finchampstead, Wokingham (England). I uploaded the trace and mapped out the streets into OSM.

It's my first entry and I can't wait for next thursday to see my work up for the whole world (or at least the whole of Finchampstead)!

I've been arguing with my partner the past couple of days about Flat Earth Theory. I'm sensing I'm about to be ridiculed here, but I actually quite like the theory of a flat earth. It doesn't affect my daily life, and I continue to believe that the earth is spherical, but the flat earth theory can be used as a step into challenging people to question the beliefs they have simply because scientists say so.

However, politics and conspiracy theories aside, I would love to render OSM data using the theories of flat earth in order to show what a flat earth would look like in great detail. I'm expecting this to be far beyond my capabilities both in terms of coding and in terms of the maths involved, however it's something I would very much like to have a go at doing (presuming of course nothing more sensible comes up for me to work on).

Talking of more sensible work, we're planning a Big Brother treasure hunt around my city centre. Last month I put in a Freedom of Information Request to the local council requesting details and locations of CCTV cameras to which they responded with a list of cameras, all with only vague locations. I appear to have found a small amount of funding for printing and prizes, and we are due to have a meeting tomorrow to plan details.

The city centre OSM map is mostly complete in terms of roads, and so we should be able to give people an A4 printout of the area with the list of cameras on the back. Points can then be given for each camera found, with bonus points for each extra useful bit of information (unlisted cameras, photographs, type, coverage, etc) and possibly some bonus points for cameras we don't expect to be found (bad descriptions or in outlying areas).

Hopefully this will all lead to complete mapping of all surveillance=public in Bradford within a couple of months.

I'm considering walking the length of Washpit Brook in Leicester (it's the brook which runs under the footbridge at the end of Church Lane in Knighton) The link below shows it on an out-of-copyright OS map:

http://www.ponies.me.uk/maps/osmap.html?z=14&x=-1.1188888549804688&y=52.6035166819531

It looks like it starts somewhere just outside Oadby. Apart from the name on that map, the only other reference I can find to it online is here:

https://www.british-history.ac.uk/report.aspx?compid=66594

I'm contacting other active local mappers to see if anyone wants to join me on a wet walk through an unmapped brook :) I can't promise excitement, but it'll definitely be a different sort of mapping experience. I'm thinking wellies will be required, and there's always the promise of a pub visit afterwards.

I don't have a particular date or time in mind, I thought I'd see if anyone else was interested. If not, I'll do it myself, but I think it could be a fun way to meet local mappers.

Last night we had the first London meet-up of 2009 at The Rocket pub in Euston. This pub seems to draw the crowds for some reason. We had 15 people along last night, a turn-out matched only by the previous meet-up in the Rocket.

Gregory was there and telling us about his Durham mapping progress. Jenny was showing us her hyper-organised paper-based mapping log book. She's mapping East of Stratford which used to be a big pocket of unnamed streets.

Hi all,
A quick update for you all for whats going on on the talk-ca list.

The Canadian Geopolitical boundaries database has been imported, it was done just before new years. ... this covers for the provincial boundaries. :)

Samples for test areas is going great, using a Roadmatcher program were it only shows roads which are not present in OSM, so then work would be needed to manually merge in the data.

We have had more discussion with the Source of the Data (Natural Resources Canada), trying to figure out how they can help, and to answer all questions and keep discussion going.

I'm working on the chart of the OSM Map Features list
osm.wiki/CanVec_OSM_Map_Features
so far there are 311 different map features, in the set of 11 distribution themes of CanVec. These themes match up with the GeoBase data.

For most of these map features, we already have an OSM tag standard. But for some of it, we will need to make up some new tags... tag:extentions.

Right now, the listing is rather mixed... so dont bother trying to fix it. I still need to add in there all of the feature descriptions.

Thats all for now,
Cheers,
Sam Vekemans

I got some days ago GPS traces from Costa Rica. I’ve been there and know the roads but at the time I was there I wasn’t interested in Openstreetmap and didn’t have a GPS so I didn’t have any tracks to use to draw roads there until now. This is a short story of what these valuable tracks helped me to do...

Hallo erst einmal.
Neu wie ich bin habe ich mich seid Weihnachten mit meinem neuen CSx und Mountainbike durch die Winterliche Kälte und bis zu 12cm hohen Schnee gekämpft.

Drei Tage habe ich benötigt alle Teile meines Zielgebietes zu durchfahren.
An jedem Abend habe ich kennen hier bestimmt viele Stunden über Stunden daran gesessen um alle Wege zu ziehen.

Hier bitte eine Entschuldigung vor weg, die Wahl der richtigen Weglinien muß ich noch anpassen an den benachbaten Grunewald.

Jetzt schaut euch mal die Karte an. Erkennt ihr Ihn?

warscheinlich nicht denn die Geschichte der Colonie Alsen ist den wenigsten wohl Bekannt:

Colonie Alsen bezeichnet die im Berliner Ortsteil Wannsee vom Bankier Wilhelm Conrad 1863 gegründete Sommervillenkolonie am nördlichen Ufer des Kleinen und westlichen Ufer des Großen Wannsee.
Die prachtvollen Villen dieser nobelsten Berliner Kolonie stellten, eingebettet in einen Park, eine einzigartige Kulturlandschaft der Zeit des Kaiserreichs und der Weimarer Republik dar.

1872 erhielt die Kolonie den Namen Colonie Alsen. Conrads Schwager General von Colomier soll zur Namensgebung Alsen angeregt haben, da ihn die Wannseelage an die Ostseelandschaft der Insel Alsen erinnerte. Damit nahm die Kolonie – im Sinne der damals typischen nationalistisch-patriotischen Einstellung – Bezug auf den Dänischen Krieg mit dem 1864 kriegsentscheidenden preußischen Sieg des Norddeutschen Bundes auf der Insel Alsen, an dem General von Colomier maßgeblich beteiligt war. Die Seestraße in der Kolonie wurde später nach ihm in Colomierstraße umbenannt.

Im Krieg zwischen Dänemark und Preußen ging es des öffteren auch um Flensburg.
Als die Preußen Flensburg erobert hatten wurde ein Broze Loewe beschädigt.

I've finished mapping the road network in Breiðholt, not counting Seljahverfi.

The road network in the Greater Reyjavík Area is now complete north of Breiðholtsbraut and south of Elliðár. That only leaves Grafarvogur, Árbær and Úlfarsfell as the major road networks with holes in them left.

I found a road on google maps to day that I didn't know that it existed, in fact it don't exist, its half of one road that is renamed, so I found a easter egg on goggle mas (tele atlas), search for "karlsrovägen, gävle" on google maps to find it, karlsrovägen is the imaginary one, and utvindsvägen the real one.

What is more interesting is what I found when I tried to confirm that it was a easter egg, I could not find my images from that survey, so I checked the local municipalities web map that gets its data directly from there gis data.
And there search could not find the road at all, the reason for this turns out to be that no property has its official address on that road, and the municipalities search only search the property database.

What really surprised me, is when I pointed out this to them, I got a answer in a few of hours, in where they say that its a know limitation and that they have a manual routine to deal with it, and this particular address will be searchable with the next data update, in a week or so.

Last weekend Anna and I finished cycling (in stages) from London to Fishguard on National Cycle Route 4.

The two bits we'd not covered were Swansea-Carmarthen, and Pontypridd to Newport. Very different from each other: Swansea-Carmarthen was almost entirely flat and traffic-free until the final miles, with 21km of glorious, wide 'Millennium Coastal Park', a peaceful railway path, and some judicious connections including a landmark new bridge.

Pontypridd-Newport was a more typical NCN mix. A railway path was followed by a bit of ducking and diving around housing estates to end up at Caerphilly Castle; a bit more housing estate led to some lovely new winding riverside paths, a railway line on the side of a valley (excellent views), and finally a typical NCN selection of country lanes. Oh, and a really annoying gap in the route at Newport, which we didn't know about until having tried (and failed) for about 1hr30 to find where the route had gone.

So NCN 4 is now pretty much complete on OSM - the first long-distance route to be so. Newport is obviously a lacuna; there's a 100-metre or so gap in Carmarthen, too, where the route seems a little imperfect awaiting a new section for Connect2; and there's a short gap in Pontypridd, too. On bits that others have mapped, a couple of streets are missing near Greenwich, and there's a tiny break in North Bristol. But none of these are more than very short gaps. More useful is that several 'braids' of NCN 4 are fully mapped, offering attractive alternative routes: the most significant is the North Wiltshire Rivers Route, a mostly traffic-free detour with some superb cycling along the Ridgeway.

So you can now use OSM as your free guide to cycling all the way from London to West Wales. Enjoy!

(And I took the opportunity to map the missing section of NCN 8, Lon Las Cymru, into Cardiff. Both this and the Pennine Cycleway, NCN 68, are also approaching OSM completeness.)
