[Talk-ca] Surrey Data

[Adam Dunn]

Asked on irc, and PDDL is okay to import, so we can do this one if we want.

Lots of great stuff in here. The transport file comes with 5 shapefiles:
traffic signals, sidewalks, road edges, road centrelines, and poles.

Traffic signals has traffic lights, pedestrian lights, beacons (which I
think are flashing red/yellow, will need a local to check some of this out),
and "fire" (probably stop lights in front of a fire department). Also
contains whether the lights are controllable, and who owns them (Surrey,
provincial, etc), among other info.

Sidewalks has outlines of sidewalks, some of them have material
(concrete/asphalt) and width, among other info.

Road Edges has the outline of roads (very high detail), along with all the
private driveways along the roads (driveways that are 1 or 2 car lengths
even!), but there's not much tag info of use here.

Road Centrelines has name, class (provincial highway, arterial, local),
surface type, maxspeed, route usage (dangerous goods, truck route), number
of lanes, address info (leftfrom, rightfrom, leftto, rightto) and owner,
among other info. The address info would be good to get, but it's tagged
onto the centreline itself, so one would have to generate separate ways for
the interpolation.

Poles has light poles, with the type (hydro pole with lights, street lights,
primary/secondary signal lights, private property lights), material
(concrete, wood, metal), colour (green, silver), height, lamp type (metal
halide, led, sodium), wattage, and particularly interesting in the comments
is the existence of a camera. This info could be good for filling in the
lit=yes value for various roads.
