[OSM-talk] Suggestion for an Unconference

[john whelan]

This is a fun one.  CANVEC has address ranges for some Canadian provinces.
Locally after I imported the address ranges I found the missing streets
because you just have the two address lines with no road in the middle.

Working with others such as CANVEC does provide a method of cross checking
for the data and in this case improves the accuracy of the map.  It also has
enabled people to fill in the basic map for some very remote locations.

What CANVEC isn't so strong at is detail on point of interests such as
restricted junctions or where there are traffic signals so OSM with imported
data gives a very good blend.
