The weather is supposed to be good, we'll have brief presentations, tutorials, plenty of hand-on mapping (for all levels) and refreshments. There's still space left, so please join us! We're hoping that this will be the beginning of more regular OSM meetups and events in the greater Boston area - something we haven't had for a while. - Lars -- Lars Ahlzen l...@ahlzen.com ___ Talk-us mailing list Talk-us@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-us
Re: [Talk-us] Tagging bicycle anti-routes
If there's a specific intersection or stretch of road that's hazardous to a law-abiding cyclist, consider cycle_hazard=* (like cycle_hazard=door zone or cycle_hazard=bike lane to right of right turn lane).

In places where use of a bike lane is mandatory, a street without one can be safer than one with, since a cyclist on the former is able to cycle defensively. (A sidepath is even worse - since it's not part of the actual road, a safe cyclist has to yield to turning traffic at every intersection and driveway.) We already tag most of the above, and a router can create its own values based on whether the user wants to ride in the gutter or in the general purpose lane. shoulder=paved seems like an obvious tag for that purpose, and I'm not sure what you mean by a 'bike friendly sidewalk'. ___ Talk-us mailing list Talk-us@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-us
Re: [Talk-us] Daily OSM Extracts for US
I'm now making daily OSM data extracts available for the US Census Regions (as per http://en.wikipedia.org/wiki/File:Us_regdiv.svg) on download.geofabrik.de. I will not do a full US or full North America extract because I think it is too big (anyone who can process that might as well process the planet file), but I think the Census Regions might make sense to some. I'm planning to add individual states later on. The extracts are in .osm.pbf format exclusively, you will need Osmosis 0.27 or the new pbf2osm (see dev list) to process them. A modified osm2pgsql able to read these files directly, and more quickly than any bzipped XML, is on its way. Frederik, Being in a border region I often need to stitch things back together. Would it please be possible that the extracts are run without clipping incomplete objects so it connects correctly when merging?

Re: [Talk-us] Tagging bicycle anti-routes
As with many OSM tags, there are objective items to begin the categorization. The final decision though will be at least partly subjective. Class:bicycle is a good start. Perhaps list specific features as a base for the ranking, then things that would drop that to lower rankings. An example of what I mean for starting values. separate paved bike/general path = +3 road with bike lane = +2 road with bike route= +1 road with a good shoulder / bike friendly sidewalk = 0 ?=-1 ?=-2 Limited access highway = -3 (should normally be no bike access anyhow) Then start to look for other factors that would lower the ranking. Frequent stop signs against the route. -0.2 (what is frequent) Roadside parking -1 (or 1.5) Busy road -0.7 (how to measure) poor surface -0.5 (how to measure) Small or no shoulder -1 User bias from +1 to -1 to adjust for local differences from the suggested standard. Add that up and round to the nearest whole number. Building the above recommendations will take time, and have to be rebalanced so they actually fit most situations. Work out starting recomendations, then tag an area and see how it matches with bikers opinions. Adjust the recommendations and try again, perhaps another area to make sure it fits multiple situations. I think up to about 10 or 15 things to possibly consider would be good. Beyond that it will be too much information and too complicated for the average person. If it takes more than about 20 seconds to decide the value it is probably too complex a system.

Re: [Talk-us] Tagging bicycle anti-routes
Someone in my area decided to try and make a bicycle map. He used this scheme: http://wiki.openstreetmap.org/wiki/Class:bicycle And rendered this map: http://bikemanhattan.info/ Now I know people are going to complain that this is a subjective tag and that it shouldn't be in OSM. And I don't entirely disagree... but oh well. It worked for him and I don't dislike the results he got from it.

[Talk-us] Tagging bicycle anti-routes
In Decatur, Georgia, Bike Decatur, the city government and recreation departments and fellow OSMers are working together to create a bike suitability map with suggested routes in the area. This is a snapshot of the map in progress: https://docs.google.com/leaf?id=0B_hqPUZzUTJMZjQwZmIzYzgtMjM3Yi00YjczLTk0ZjktNjdmZmQ2ODZlYjgy&hl=en [ Here's the data rendered in Cycle Map: http://www.openstreetmap.org/?lat=33.7718&lon=-84.2935&zoom=14&layers=C ] The next step is tagging "tricky" intersections and sections of roadway where cyclist should exercise extra caution. Any recommendations for tagging these anti-features? Any feedback or questions on the project in general are welcome. -- Lee ___ Talk-us mailing list Talk-us@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-us
