[Talk-ca] Data Source for Surrey Roads

[Paul Norman]

PDDL - essentially public domain. Surrey makes their data available at
http://www.surrey.ca/city-services/658.aspx and the roads data is found as
trnRoadCentrelines in SurreyProperty or SurreyTransportation. Surrey really
seems to get open data. They make their data available under open terms and
provide lots of detail in their shapefiles, and let the users decide what to
do.
