The mapping companies get it wrong again...

Posted by andrewpmk on 6 July 2008 in English (English)

(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 Navteq has a slightly outdated but otherwise correct map.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.

Location: Cataraqui, Kingston, Ontario, Canada

Well done.
While I was on holiday by car we kept passing a new housing development and I considered getting my mum (the driver) to drop me off to map for a couple of hours. Adding something within a short time is cool cause it brings up the point how awesome us OSM mappers are!
