Have a look at the source, CANVEC includes the address information for a number of provinces which correspond to their roads. Generally speaking their roads are fairly accurate.<br><br>Cheerio John<br><br><div class="gmail_quote">

If a road gets moved to a new location, does one create new parallel<br>
ways and tag them as address interpolation ways? What's the standard<br>
offset from the roadway?<br>
<br>
Where does one get address numbering information from? For some places<br>
it can be easy, where you start at 1, and work your way up, but what<br>
might the upper limit be? Guessing doesn't work, as can be seen in the<br>
NavTeq and TeleAtlas databases that have my house number around 63 or<br>
so, yet there are only 40 houses on my street, with the last house<br>
being #40. Where there are houses, one can simply read the number off<br>
the house if it is posted, but in areas where no houses yet exist, one<br>
might have to resort to looking at another source document.<br>
