nothing to bitch about

Zapsal jcomeau_ictx 7. 10. 2007 v jazyce English.

i know, most of my "diary" posts have been grouching about something or another, but i'm finally seeing good results in my local area. thanks to everyone at OSM for a great job. using the 'search' box for 'pubs near columbus' actually brings up only the two i mapped, including my shebeen! and there are umpteen other towns in the US named Columbus, including a rather large city in Ohio, but i guess nobody has mapped them yet...

Místo: Luna County, New Mexico, United States

wtf?

I-10 data seems to have disappeared between Deming and El Paso. It's already rendered on tiles@home at level 12, but it no longer shows up in Potlatch nor in JOSM. Database crash or something I guess. It's getting tiresome -- that's the third time I traced out that road on the satellite images only to have it disappear.

come on, USians

We've got both the TIGER database and Yahoo! imagery to use, let's get cracking! You gonna let these Brits, French, German, Norwegian, etc. run circles around us?

I lost about 100 miles of tracing I-10 through New Mexico and Texas (from the Yahoo! satellite images), once due to hitting the escape button, and once because my computer froze. Damn. And now I'm getting a lot of packet loss, so it's slow going. But because "roadways" show up at all magnification levels, it's rewarding to plot interstates, you see real results every Thursday.

I really don't know how useful the TIGER data is going to be, at least for the streets. It's way more inaccurate than tracing the Yahoo! satellite images. Maybe good for the street names in an unfamiliar area.

My nodes, segments, and ways uploaded with JOSM show up in the edit (Potlatch) program, but still don't show up in either the Mapnik nor the Osmarender maps. Supposedly Mapnik updates weekly on Wednesday, and it's already Thursday GMT.

Good news is that the placename search was only broken for 2 days or so.

Guess I have to figure out how to write my own tiling program and mirror OSM on my own server. Then I can stop bitching and do the work myself.

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.

data backlog?

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.
