By just looking at a 1:50000 map of the area left and right of the Autobahn A3 between Erkrath and Mettmann, I would have never considered cycling there. Just for completeness I went there to track some paths and found a very interesting area with many more ways than expected from the map. Again I was amazed how much more lifely the experience of a rather small area can be if you want to map all the tracks you can find there.

Still I have to go back there, because I could not finish everything. I must say, however, that I should have made the trip in summer. Quite a few tracks are still terribly muddy. Not that it really kept me out, but I am not exactly looking for this kind of experience.

More progress in the java applet to view OSM data...

Allowing keyboard browsing, going left, right, up, down, zoom in, zoom out and back to GPS fix.

Included NMEA decoding function (only GPRMC for now)

Still some stuff to go:
- Bluetooth serial link with GPS
- Caching of data into local database
- Reading Cell ID from GSM phone
- Automatic GPX upload as you go through unmapped places

Server needs:
- Cell ID database
- Real time traffic data from GPS users

at the bottom of the Grafenberger Wald. In addition I finally managed to connected the two ends of Bauenhäuser Weg. Now I am trying to upload from Josm, but the server seems to have an overload. It just doesn't move.

Has anybody thought of a server where you could have people uploading their current position, heading and speed to monitor the traffic and avoid traffic jams ? I'm thinking about implementing something along those lines, but I'm aware that the project will only benefit when there is a high number of people collaborating also. I'm also thinking about using the GSM cell tower info from the cellphones so that you could get a location fix without a GPS, but that's going to required the mapping of the cell towers. Anybody can help me out pointing to projects that try to address these ideas ? Thanks in advance, Diogo

Alueen kartoitusta..

Das schrie geradezu nach einer ausgiebigen Radtour, und in der Tat konnte man nur genießen. Auf der Tour von knapp 40km mitgekommen sind Feldwege nördlich Wettmershagen und im Ilkerbruch, ein Wohngebiet in Calberlah und der östliche Serviceweg am Elbe-Seitenkanal. Was für ein schöner Tag, und was für ein wunderbares Hobby.

I've been making progress with the mapping. I'm still using my OpenMoko phone: Neo1973 and I'm still loving it :)

But now there a beginning to come programs for the Neo which can use the map we all a making. This is just so cool. It's really fun cycling around, navigating the city with a map I've helped create. It makes me proud, and gives me a lot more willpower to just go out only tagging new roads.

My previous try to fix germanys bigges continous wood turned out to be more destruction than fixing. It was reverted by user rrissek.

It created some white tiles, and fixed others that were white before, giving a rather disappointing total.

I think I now understood the way it works - finally. The Harz outline has to go through every tile inside, and it is not enough if a segment goes throug the tile (I know, there are no real segments any more, but you know what I mean...). There has to be a node.

I think it was not very nice to modify the Harz itself (it has 473 nodes even without my fix). So my current try is based on new way inside the Harz, tagged as natural:wood. It has a node in every zoom 12 tile inside the harz, and should finally work. It may take some time to get rendered, because the T@H server is overburdoned right now.

Despite this, I uploaded about 20 gpx files that I missed until now, and traced the viallages around Wernigerode using Landsat images, tagging them landuse:residential.

Did some work on a suburb of Uppsala while listening do this weeks podcasts, Uppsala being one of the few places where yahoo has high resolution imagery in Sweden.

I failed to save the coordinates for the previous entry. Here they are.

I've been mapping for a while south of Barcelona, using Yahoo imagery mostly, and some traces of mine where the imagery is outdated. I've also used GPS traces to correct the offset present in the ortophotographs.

In the last couple of days I've turned to the cadastre to find street names not in my inmediate vicinity. I gather this is most likely OK from the wiki and the mailing lists. If not it would be nice to have a tool that would allow me to mass edit specific tags to delete the names.

It's surprising how much a single person can do just by using potlatch. Looking forward for this project to gain popularity. Also looking forward to the day when I can use a routing application based on OSM, and better yet, being able to fix errors whenever I find them.

Cheers to you people for this wonderful project.
Juan.

So, heute habe ich nun einen neuen GPS-Bluetooth-Empfänger bekommen, zu dessen Bestellung ich mich neulich entschlossen habe. Nachdem ich in den vergangenen Wochen festgestellt habe, dass mit alter GPS-USB-Maus und Laptop ein ordentliches tracken nicht wirklich möglich ist, habe ich mir dieses Ding nun zugelegt, um günstig mit meinem Handy aufnehmen zu können.

Vorhin habe ich dann gleich meinen allerersten Trace hochgeladen, der allerdings noch nicht viel hermacht. Ist die obere Hälfte der Straße in der ich in Margetshöchheim wohne, einmal runter- und wieder hochgelaufen. Wenn ich in nächster Zeit - nach Semesterende - dann endlich mal dazu komme, mich ins Mapping von Margetshöchheim zu stürzen werde ich das aber denke ich nochmal "sauber" aufzeichnen :)

Since it is possible or even probable that Yahoo! is changing owners, I am now tracing stuff from their aerial photos that they allow us to derive maps from. Who knows what happens with that agreement in the future.

I concentrated on features that are hard to reach, like the banks of rivers (I traced the Neckar up to Remseck); or do not have a name, like tracks in vineyards.

Last weekend I decided that it would nice thing to have a little apple script which would download, configure and install Tiles@Home on my mac and possibly on any other apple machine out there waiting for OSM to eat up its CPU time. After installing Tiles@Home on Debian with virtually no problems at all I thought this might be a very easy thing to pull off... Well, after spending almost a whole day on downloading, compiling and installing thousands of little perl-scripts and native libs in order to get it running, believe it or not, I changed my mind. But hey, its working now :)

If you have alot of time and want to install T@H on your Mac too, take a look into the Wiki. I've made a *small* installation guide for OS X there. Its only 10 times as longs as all the others ;) osm.wiki/index.php/Tiles%40home/Install_Guide#Installation_instructions

Anybody out there having some firsthand experience on installing T@H on windows?

Slowly but surely the out-of-the-way lanes and back streets are being mapped. I'd say that the "top" two-thirds of Armidale is complete. The "bottom" third probably has about two or three hours work GPS surveying left to do - though I don't know when those few hours will happen.

Potlatch 0.7 testing again. Edit background photo loading very slowly, but the streets loaded quickly. Waited several minutes and only one photo tile loaded, and not the one I need to tell if I need to straighten Pacific Ave between Perris Hill Park Rd and Garden Dr.

I'm all for mapping a large number of unmapped roads in my area with my GPSr but I'm still waiting for the one small stretch of about 1Km of road that I did as a trial last weeekend to appear on the main map. I'm probably missing out on something really fundemental - It's there on the Potlatch map as an extension to an existing road when I go back to it (for days now) but doesn't appear on the main browser map.

Until I see my small test work out, I'm not going to spend the many hours of effort that's required to translate GPS traces into meaningful map data unless I can see it's actually being accepted.

From my experience over the last couple of days, better information for beginners would be good too...
