The mapping companies get it wrong again...(Finally) mapped and uploaded a big new subdivision in Kingston, Canada. It is still under construction, so I will have to come back in a year or so to map new roads. This one is by far the largest. As usual, the mapping companies got it completely wrong. Navteq has a slightly outdated but otherwise correct map. TeleAtlas, on the other hand, has downright wrong data; its map appears to be based on an old plan of the subdivision. Not only does it show roads that have yet to be built, but it shows a quite different layout from the parts that have been built. It is utterly and completely wrong! (I reported it to them via the online form, but I fully expect that it will take them about 5-10 years to fix, by which time OSM will be fully complete.)
See http://geo.topf.org/comparison/index.html?mt0=googlemap&mt1=tah&lon=-76.5552449&lat=44.2630579&z=15 and feel free to laugh.

New GPS
Purchased new GPS (Garmin eTrex Legend HCx) last Wednesday. The accuracy is quite good - usually about 5m after obtaining a good fix with WAAS on (it's off by default). Have been using it in conjunction with Yahoo photos to map parts of Toronto - it's much faster to use it plus a voice recorder than it was to use pencil and paper and it allows me to map areas that are difficult to make out on the sat photo. Haven't mapped any areas with no sat photos - yet - but undoubtably I will find some new subdivisions soon enough.

Mapped all the buildings in U of T and Ryerson
Mapped (almost) all the buildings in University of Toronto (where I'm going to school right now) and nearby Ryerson University, tracing their outlines using Yahoo imagery. I missed a few buildings because they were missing signs or were under construction. I added the addresses of most of the buildings (shown on the signs) so if someone gets a geocoder running then it can use them. They should show up on Mapnik tomorrow.

New York
The TIGER import has restarted again. If you want data for New York City, just email Dave Hansen, the person who is doing the imports, at , and ask him to move New York up the queue.
