I think the most useful is the orthophotos, followed by the address data, followed by traffic signals. From what I've seen the alignment for roads in surrey is pretty good already, although it might be worth converting those so they can be used as a background like I do with CanVec.
For data like the light standards it would be cool if we could do lit= from them, but importing the light nodes themselves might be an issue. Although there is a tag for a node to mark it as a streetlight, keeping any nodes added up to date with any changes would be hard. I definitely think that it's pretty cool that they've made available all this detailed data and essentially left it to the users to decide what is relevant. It may be that some of the data never gets used, on the other hand, if I wanted to go and look at the efficiency of surrey street lights by area based on lamp type, they've given out enough detail to do so.

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.

I've glanced at some of the files in ArcGIS Explorer and the level of detail in them is excessive if anything. That being said, I wonder if there's some stuff worth importing. What interested me is the orthography data, being PDDL. They have 2008 in GeoTiffs at http://www.surrey.ca/city-services/4911.aspx and a 2010 slippymap at http://cosmos.surrey.ca/ArcGIS/rest/services/ORTHO2010/MapServer The 2008 are 40cm resolution color, and the 2010 are 10cm resolution color. _______________________________________________ Talk-ca mailing list Talk-ca@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-ca
