OpenStreetMap
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.

I have done quite a bit of tracing similar to the work you are doing, it is good to see other people working along the same lines. :)
This fine detail is what really distinguishes OSM from other available maps. Keep up the good work.

Hi Buck!
Thanks for the supportive comment!
I saw from your diary you are also focusing on HOT mapping, great. Have you also done pedestrian mapping? It would be great to see some examples in that case, to share ideas about tagging schemes, etc. My example would be the change set from yesterday, then.
It’s of course alsinfo interest to make sure there is at least some consistency in how it is done in different areas, to allow creation of routing rules that will work “everywhere”. Consistency is one of the big challenges in crowd sourced efforts, IMHO. But challenges are fun. :-)
Take care, Marty
