</div>With respect to the road network one thing to consider is update frequency.<br>
The Canvec data is updated twice a year, geobase seems to publish when they<br>
get the data ready.<br>
<br>
Right now only 4 provinces/territories have street names and 3 with<br>
addresses. I think we are going to be very anxious for the updates that add<br>
street names to the other provinces. I am not sure how far canvec lags<br>
behind the geobase updates.<br>
<br>
Pulling the road data from geobase doesn't exclude pulling additional layers<br>
from canvec. I think we would still want to deal with each layer (or<br>
related layers) as seperate projects.<br>
<br>
</blockquote><div>I agree with you entirely. For Geobase themes included in CanVec there will be a lag between 6-12 months. CTIS plans for 2 releases a year. But depends on the timing with the provinces we may miss last minute data delivery. Also I prefer working with Geobase tiling for import. It is easier to work 13 tiles (NRN) than with 13000 NTS 50K tiles. For the National Hydro Network, Geobase tile is the drainage areas. There are about 1000 of them still easier than NTS tiles.<br>
