Fahrt nach Lambrecht getrackt und eingegeben

Schlängelei mit dem Fahrrad durchs Neubaugebiet. Hab ein bissel die Übersicht verloren, was da nun noch residential war und was Fußweg. Also irgendwann nochmal...

There are some problems with the t@h approach to rendering maps, but there are two that might develop to the point where they become show-stoppers:
(from my point of view)

A) The server is too slow.
B) The clients can't handle certain tiles.

Yes, the server is too slow. It cannot handle enough clients to keep the world up to date soon, let alone retroactively re-render everything that need to be rendered when a layer gets added to the portfolio of things we want to show.
For almost all year the server has not shown a similar improvement in speed to everything else OSM.

Also since several city-tiles are getting very complex, there are fewer and fewer clients that can infact render those tiles. Next to nobody has a PC with 12+ GB of RAM laying around. The problem being that if we start precutting the tiles into more manageable chunks the osm to svg transformation becomes prohibitively slow. There should be a more effective way of keeping svg complexity down when rendering high-zoom subtiles of densely mapped city areas, other than mucking around with the osm data.

Iniziato a tracciare quasi per scherzo dopo essermi trasferito quà, all`inizio di gennaio 2008 ho iniziato, partendo da zero, dopo aver percorso centinaia di km in bici e moto e un migliaio in auto, la città sta prendendo forma e le provincie limitrofe pure. Ma il lavoro da fare è immenso,in modo speciale per il resto della Thailand

die Südseite von Raibach ist jetzt als GPS-Trag erfasst.
.. jetzt muss ich nur noch Zeit finden die Straßen anzulegen.

Am WE mal wieder etwas unterwegs gewesen und die eine Hälfte von Essingen
getrackt. Mal sehen wann ich wieder hinkomme und den Rest abfahren kann.

Knöringen habe ich auch mal angefangen, sollte relativ schnell drin sein, da
der Ort relativ klein ist.

Auch mal wieder im Horst unterwegs gewesen, aber das ganze ist ziemlich
verzwickt aufgebaut und einige Straßen sind nur mit Fahrrad oder zu Fuß
zu tracken.

My hopes were high when I read about OpenStreetMap. I thought that for the first time there is a place in the mapping world where every bit of the earth surface is treated equally. This feeling was short lived as I navigated away from my address in the UK to my place of birth, the city of Kumasi, Ghana, West Africa. It was then that I experience again the pain in the truth contain in this statement; "that's just the way it is, some things will never change". This statement has been used in poems, speeches and songs. This statement is familiar to a lot of people. But for people like myself who continually live and struggle to break free from that other side of life on earth where some things are not changing, we sings these songs, listen to these speeches, read these poems but believe that some way somehow, some of these barriers will begin to break. We have fervent hope in the Open Source movement. So I urge OpenStreetMap to do something about the lack of aerial photo backgrounds in some of these places. Let nothing stand in the way of the movement of change. Open Source!!

Just came back from a weekend up north. Thought that a full gps would be plenty of track recording memory, but I should have known better. Mananged to fill in the loop around Hvammstangi, but didn't add in all the side roads, I was touring, not mapping.

Unfortunately, coming back down the east side of Skagi, I ran out of trackpoint memory, and without the laptop, that was it for the weekend. Oh well, lots of km added, and lots of pictures taken. Still a great weekend away :)

Along the way I've pushed some coastline around, and also, because it had been bugging me for a while, the road between hveragerði and selfoss has been downgraded back to primary. It's one lane each way, and even though it's planned on moving to 3 lanes, there's no way it could be called a trunk.

Short bike ride to map some of lcn 88, which goes by near me. Must look up where it goes to and from sometime! Usual problem of how to map different types of physical presence: separate lane, pavement with markings, using service roads, short breaks, etc. Then on way back watched random cricket match and mapped the micro detail inside Oakwood Park, and had a nice coffee there.

It looks like there's something screwey with the tracks I'm recording while driving around. I have a computer in my car which runs Kismet. I plug my eTrex Venture GPS into it, letting Kismet record a track from the NMEA stream (via gpsd) and then process Kismet's GPS logs into GPX files. But I just compared one of the Kismet data sets with a track downloaded directly from the eTrex with gpsbabel and the tracks are consistently offset from each other by about 100 metres or so. So now I've got to work out where on earth the error is being introduced. The GPS is set to WGS84 and I presume Kismet is too dumb to try and do any kind of datum conversion on the coordinates so I'm a bit stumped.

I've been mapping the Royal Holloway - University of London campus and I've had a couple of problems.

The main building is '8' shaped - a rectangular building with two large courtyards/quads. I'm not sure how to make it show like this, I've managed to cut out one of the quads but not the other. Anyone able to suggest how best to do this?

Adicionei o trilho dos moinhos para BTT

Am 1. hat ein Freund den Keller seines Hauses gebaut; eine gute Gelegenheit, den Ort zu erfassen. Außerdem habe ich mich ein wenig verfahren.
Diese Ecke von Leipzig war auch noch nicht erfasst(erledigt).
In Schkeuditz habe ich auch noch einige weiße Flecken entdeckt.

If you use the simplify way plugin for josm. Then if you add the parameter simplify-way.max-error to the advanced preferences you can adjust how much the way is simplified.

I use 250 to simplify ways which are mountain bike and bush walking tracks.

Also despite the warning about restarting josm, this is not required for adjusting the value of this preference.

Just started today with my new Wintec WBT-201 G-Rays 2. Nice device, size of a large matchbox and usable software, although sometimes funny translation of the manual from Taiwanese to English :-)

Puh, jede Menge zu tun da. Da fehlte sogar ein Stück B500! Ansonsten auch so noch jede Menge kleine Straßen nicht erfaßt. Und Wald ist da auch noch nicht wirklich eingezeichnet...
420km haben ne Menge WPs eingefahren. :-)

Last days make a little trip to my home town Ussuriisk and back to Vladivostok. Trace federal road M60 and part of Trans-Siberian Railway. Correct railway and add stations. And, of course, map some central streets at Ussuriisk.

I've been busy mapping out the wooded areas of Windsor Great Park and correcting the paths and roads in the park, Englefield Green and Egham. Having patches of green over the park makes it look much better, though unfortunately the Yahoo! imagery runs out in the middle of the park - someone should suggest they buy some more. Anyone worried about what Microsoft might do to Yahoo! maps?

On an unrelated note, I noticed this annoying rendering issue:

Go to the linked map and go to zoom level 14 on Osmarender. You see a massive 'Truss's Island' label for what is a tiny place (< 150m long and about 30m wide). Mapnik does a better job of this and scales it more appropriately.

It seems to be caused by the 'place=island' value, Osmarender must assume that islands are significant I guess...

Back to work!

Third and final trip to Saffron Walden on Friday, changes now uploaded. Saffron Walden now complete. Nothing of any great note in the area that remained to be filled in, except that SW has horrendous traffic problems for a place of its size, and despite the fact that the M11 bypasses the twon, and even the old A11 trunk road also bypasses the town. Everywhere there were queues, and the one-way system doesn't help that much. Where is everyone going in the middle of a Friday? It's a town where you could walk from one end to the other in half an hour, yet everyone seems to drive everywhere all the time.

To finish off this delightfully sunny day I surveyed the much pleasanter rolling hills west of SW to fill in a hole this side of the Cambs-Essex border containing the small villages of Strethall (which seems to be the church and not much else), Elmdon and Littlebury Green. This means that everything north of the B1039 SW to Royston Road is now complete right up to Cambridge and beyond, and north east of SW as far as the edge of Haverhill.

Royston, Hertfordshire, should perhaps be my next target.

Went for a very nice walk on the open heathland in the forest near Hilversum (just next to the local airfield, which someone should still add to OSM I see) and it looks as if the pethora of walking trails that exist there are still nowhere to be seen in OSM. I added the route we walked and next times we will walk there I will try to get as many of the uncharted paths as I can.
