Vågsbygd has never looked better :)

Posted by Jarl Arntzen on 2 August 2012 in English (English)

Thanks, community! I was really dreading the task of remapping Kristiansand after the redaction bot had been cut loose on the world but this has so far gone a lot faster than expected.

Vågsbygd, Kjos, Voie and Andøya are now in pretty good shape and Jaktodden has actually never looked better as before it was just marked as a residential area without any roads.

115 are done and 30 validated according to the Task Manager (50% done soon) and I expect the last 50% will be a lot easier :)

Big chunks north of Lund, the area around the University of Agder, are still blank though, so there's tracing left to do.

South-east of Varoddbrua, Odderhei and further south are blank and even an entire island has gone missing south of Tømmerstø. It has actually been traced again but updates of the coastline seems very infrequent. Back north of E18 Hånes still needs to be traced.

I think I can verify at least a couple more squares at the OSM Task Manager but I'm turning in for the night.

Cheers,

Jarl

Nice! Looked a bit scary on OSMI license view before the redaction. I just hope you are calibrating the Bing images. Looks to be quite a bit offset. [10.16; -2.28] looks like a good value, in JOSM, around the railway station but I guess the offset varies a bit.

Yeah. Kristiansand was mostly red spaghetti, there. I havn't looked at the map calibration but once I get my HTC Desire GPS working again, I'll double check. Thanks for the suggested offset values, are those in meters?

Yeah, I think they are in meters. There are quite a lot of old traces around the railway station and the nearby junction that I used to approximate the offset. Good luck with the remapping. :)

@joakimfors: Right. I've seen the the disjointed roads at the edge where the two imagery qualities meet. I havn't done any adjustments yet, though. In old Potlatch, there was an option for moving the background image, do anyone know if this is available in Potlatch 2? If not, I'll just try to do this in JOSM instead.
