Mapping projects in Edmonton
Major arterial roads have been mapped. Southwest and Southeast portions of the city have streets mapped out, Mill Woods recently done (roadways traced from Yahoo imagery Aug 2008 User:Ve6srv, tagged Sep 2008 User:Xelloss). Downtown and the central area is also mapped. Thanks to User:Carbon-14 in Aug 2008, the Northeast/Pilot Sound area is also mapped out. Beverly and Clareview are now mapped out as of Nov 2008 User:Xelloss. However, much of the detail information for the rest of the city (North, West) still needs to be filled out. Neighborhood information also could use entry. Mapped out many of the river valley multi-purpose trails and some single track trails Sep 2008 User:Xelloss but they also can use work. Started on lanes=x modifications suggested by User:Mungewell for larger roads (I.E. lanes=4 for 2 lanes of traffic in each direction) Sep 2008 User:Xelloss.
If you would like to help map Edmonton, User:Xelloss would be interested in setting up Wikiproject for Edmonton so we can coordinate mapping activity and help reduce overlap.
Mapping guidelines for Edmonton
Here are some suggested guidelines for road classification in and around Edmonton and Alberta. These are not authoritative, but should help ensure consistent classification of roads around the city.
Highways and provincial roads
Guidelines for Alberta highways and provincial roads can be found in the Alberta Tagging Guidelines.
City of Edmonton guidelines
- To allow for expansion East and South, the city has adopted a quadrant naming system. Every street should have a quadrant appended to its name (NW, SW, etc.). Most of the city is in the NW quadrant, but newer areas of the city may be in other quadrants (particularly SW and NE). For example, 23 Avenue NW, rather than 23 Avenue should be used.
- Street names should be in full, not abbreviated, to follow Canadian tagging guidelines. In other words, 109 Street NW, rather than 109 St NW should be used.
- Street names with suffixes "A", "B", etc. appended should have the suffix capitalized (31A Street NW rather than 31a Street NW).
Highways that run through the city are classified as described above. In addition, they should be tagged with their street name (e.g. highway=trunk, ref=16, name=Yellowhead Trail).
Most provincial highways entering the city should not be classified as trunk since inside city limits, the highways tend to have traffic lights and other intersections impeding traffic flow. Thus, any sections of trunk highway with large amounts of traffic lights, intersections, or lower speed limits would usually be demoted to primary.
Other roads can be classified as follows:
- Primary: Only provincial highways should be tagged as primary. Slower trunk sections may also be tagged as primary (see above). Usually lanes=4 or higher if un-divided, lanes=2 or higher if divided (one way per direction).
- Secondary: Major arterial roads that are not numbered highways. Generally speed limits of 60 km/h or higher. Usually lanes=4 or higher if un-divided, lanes=2 or higher if divided.
- Tertiary: Smaller arterial roads, typically with speed limits of 50-60 km/h . This includes major residential roads that are significant thoroughfares in their neighbourhoods. Tertiary streets are usually non-divided ways (if a tertiary is divided for a fair distance, consider upgrading to secondary). May be lanes=2 or lanes=4.
- Residential: Most residential roads (any that aren't considered tertiary). Speed limits are (almost?) always 50 km/h and usually only has one driving lane in each direction (lanes=2) which is also the default if no lanes tag is specified. Residential roads that have more than one lane in each direction should be considered for promotion to tertiary.
- Unclassified: Roads that do not qualify as tertiary, but are in commercial or industrial areas. This would include much of the downtown core. Unclassified roads are roughly the same as residential roads, but are outside of residential areas. Like residential roads above, if a road has more than one driving lane in each direction for a fair distance, consider promoting to tertiary.
- Service: Back lanes and similar unnamed paved roads. Speed limits below 50 km/h.
- Track: Unnamed unpaved roads, not suitable for heavy travel. Access roads for parks or similar areas (if paved, upgrade to service).
All roads with a classification above "service" should be named.
Walking and biking trails
Walking paths can be tagged with highway=footway for paved or gravel paths. If bicycles are allowed (as they normally are), add bicycle=yes. for consistency you could optionally add foot=yes although that is implied for highway=footway. Areas with steps (e.g. the stairways that access the river valley) should be tagged highway=steps instead along with the foot=yes and/or bicycle=yes tags. Single track trails for dirt paths through brush, etc. are marked as highway=path. These should also have bicycle=yes and/or foot=yes as applicable.
