Very diverse mapping today. First I warmed up with some buildings in Haga, Göteborg, Sweden. Very accurate Bing tracing is possible, due to the high quality aerials over Göteborg.

Then on to some building mapping in Padang, Indonesia, as part of the Humanitarian OpenStreetMap Team effort to trace all buildings in this area that is prone to flooding in the event of earthquakes in the area. I’m very satisfied to actually do some mapping here, finally. The Bing satellite imagery is of quite poor quality, compared to the aerials in Sweden, though. That, combined with my lack of knowledge about the type of buildings in the area, makes it a but frustrating.

Finally I continued my effort with doing some high-detail mapping in my home area, adding sidewalks. The objective is to be able to provide true, detailed pedestrian routing for the blind and people with mobility impairment (e.g. in wheelchairs). I try to map also where there are sloped curbs etc. Tedious, but rewarding.

Just wanted to express some joy over the super high quality aerials provided by Bing maps. Tracing buildings in great detail has now become very simple, albeit somewhat slow due to my perfectionism. But I trace in two different modes, to get some quick rewards once in a while: really detailed or just really quickly drawn building outlines.

In general, buildings are a lot of fun. Lots of tracing, less thinking, and a very visible result.

This post is mostly for my own record - no questions of general interest in other words (except that I just found an iPhone App that can generate GPS Traces, and then allows for direct uploading of those to your account - gotta try tomorrow).

Yesterday I started mapping my home region in Göteborg, Sweden. I added buildings, addresses, parkings and a couple of footways.

I then went on to map around where I grew up in Ingared, outside Alingsås. I also manually adjusted a road that was not correct (the GPS Trace had lost connection, apparently, so it was just a straight line for a couple of hundred meters) near Gallvik, Norsesund. I also started mapping some addresses in Gallvik. Once I've traced the small dirt roads around there, OSM will probably be the best map there is for this particular area :-)
