Folks, I've been working a few months on a project which is now ready to launch, the DC Sidewalks Project: http://dcsidewalks.emacsen.net
As many of you know, we have excellent new routing software, and it does a great job for cars. But we also have pedestrian routing, and right now we have very poor data for that in the US. I'd like to change that, and I'd like your help. What I've done is to create a customized PL2 instance which renders streets and highlights missing sidewalk data. I also provide a background layer of imagery, showing the pavement. From these two things, you can determine if a road has a sidewalk, and mark it up using a simple sidewalk={both|left|right|no} tag. This will allow a router to determine if the street is walkable. Right now the data is limited to Washington, DC, where the pavement data is publicly available. This project is more than about sidewalks. It's the first of its kind, a customized Potlatch 2 instance with customized imagery, MapCSS and presets. I hope to be able to use this technique to make more custom PL2 instance sites, where mappers can focus on a single feature. The site is going to grow and change over time, but everything there works today, so after months of working on it, I'm finally formally announcing it. Happy mapping, - Serge _______________________________________________ Talk-us mailing list Talk-us@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-us
