I found about OSM a while ago but lacking a GPS unit and living in a blurry Yahoo country ... I didn't involved myself, but now that i have my new Garmin FR 305, I can train and map at the same time :)

So now I'm mapping my town wich seems lost in nowhereland on the map ...
Belgium wake up, we have work to do !!

OK, so I write a script to extract single roads (as a 'way') out of the TIGER data extracted by the tiger-to-osm script. Then, since the osm database files can't be uploaded (that I know of) directly to OSM, I had to run it through JOSM. JOSM loses the 'way' data on import, so I have to add it back. No biggie. Then on upload, it barfs. See my blog for the whole sordid story.

Yes, I know it's a work in progress but it sure can be frustrating at times. I'm sure I'm doing something wrong, otherwise OSM wouldn't have anything accomplished at all.

Is the importing of user data automated? If so, it seems to be stuck at a point 4 days ago


Guess I'll find out pretty quickly if HTML is supported in these diary entries...


Can anybody comment on the legality of using Google Maps to get approximate lat/lon points, formatting those points into a GPX file, and uploading to OSM? I just want to know if I can be open about it, or if I have to be sneaky. It's inaccurate enough that nobody could tell, by looking at the data, how it was sourced... but if this is really a Bad Idea, I'll just have to come up with another method, or save up for a GPS unit.

This is fascinating project. It is exactly the way it should be done. Today I mapped some roads in Prague and just by looking what still has to be done I start to get the idea how huge all this is. We need at least 10 times more people from Prague to make something which we can call The Map.

Tonight, in my continued quest to make my computer do the mapping for me, I wrote a tool to use Landsat imagery to detect land and sea tiles, and automatically update oceantiles_12.png. This is important, because errors in the ocean tiles list are causing some islands to render as lakes in t@h.

Now, I just need to get svn access myself, or give the modified oceantiles.dat to someone who can commit it.

Hey, I finally found the diary thing here! Maybe I'll start using this instead of tracking progress on my user wiki page...

After a few weeks' absence, I'm back, and working on large-scale stuff (lakes provincial highways) instead of urban street mapping. Back in June, I wrote a little tool to trace lakes from Landsat data which does a great job, and tonight I used data it generated to correct morwen's coastline import of Lake Manitoba and my earlier hand-tracing of Lake Winnipeg. It was way, way better than my hand trace, and mostly-but-not-always better than the coastline import, so I'm pretty pleased. I'll have to try to get svn access so I can get this tool in there for other people to play with.

Fascinating project, this openstreetmap.

I have already started contributing: a few road in Freising and a few Roads in Aschheim.

I will be concentrating on the area around Aschheim, an area bounded by the A99 in the north and east, by the A94 in the south and the river Isar in the west.

Apart from that I will of course always have my GPS with me.

Using GPS and a digital voice recorder works best for me.

Have been adding some parks in Hackett. Some of these are are fully bounded by roads, and some are also adjacent. It seems its impossible to re-use road segments all the time for those parks, due to the requirement that area segments all are either clockwise or counterclockwise. Seems like a shame, the outcome of this will likely be that features which really share a boundary will be mostly mapped completely seperately. Actually thats currently the only way possible to do it in Potlatch anyway (which is not a criticism of Potlatch), and since its so much easier to map features like parks from the aerial photos, how Potlatch can do it, is the way it will generally be done.

I am more and more impressed by Potlatch though!

It's been odd - as I uploaded the track logs from this weeks wanderings, I found that more than half the streets I hadn't travelled before had already been done by Norky and Blackarrow. Great work guys. I intend to continue to thicken the residential roads in Tarring whenever I go there, but I'm going to move back to focusing on Chichester (where I live) 'cos you guys are obviously doing a great job with Worthing. May even have to head over to Bognor Regis and try and get a little more roads in there. Nothings happened there since I last did a batch about a month ago.

Regards, Bevis.
