I'm generally working on the Portland, Oregon area with an emphasis on Washington County and Beaverton.

See also my OSM diary for periodic updates.

Most of my efforts are in aligning Tiger data and adding a few new streets. I also work on unbraiding streets anywhere in the U.S. Let me know if you find an area with a bunch of them.

My main WMS layers for JOSM are:

  • USGS urban area photos



My GPS logger/receiver is an i-Blue 747 Bluetooth+USB Data Logger. It is very accurate and has a very fast lock-on time. Often I use it alone to capture tracks and then upload them from my desktop. Other times I use it with my Nokia N810 internet tablet. I never use the N810's built-in GPS for capturing data, since the iBlue 747 has much better reception.

I also use a Garmin StreetPilot C330 to display maps while driving.

I'm still looking for a good vector-mapping application for my Nokia N810. Maemo Mapper is great, if you have pre-downloaded map bitmaps or have always-on Internet. But I want a vector-map application where I can download an OSM area and always have it available at any resolution.

  • Onion Mapper looks like it has the right features. I can't find one compiled for OS2008 Diablo (the Chinook one won't install for me), and I haven't succesfully figured out how to install and use the maemo cross-compile tools on my Ubuntu system. The docs are a moving target, so correct matching versions are hard to determine.
  • Navit looks good, and has a binary installer that works on OS2008 Diablo. Configuring it through the xml config file is a lot more confusing that configuring MaemoMapper. Still working on it.

I like the spirit of OSM. I trust the license working group to figure out the right license to make sure some bad guy doesn't exploit OSM, whether that uses cc-by-sa, ODbL, or another one with a similar intent. I don't care what happens to my own particular contributions.
