OSM’s architecture is powerful, yet can be way too intimidating to invite less tech-savvy newcomers to contribute. This discussion puts some things on the table that the OSM community at large isn’t talking about enough.
My Ignite talk about the OSM Tampa Bay mapping group at WhereCampTB last weekend — and what we’re doing to grow and improve OpenStreetMap in the Bay Area.
Ito World has created a tiled layer showing the status of the TIGER imported road data for the US on OpenStreetMap.
The layer shows roads that have been reviewed, not reviewed, and when they were last edited in the database. A surprising number of the major roads in the Tampa Bay area have been reviewed, but that doesn’t necessarily mean the geometry has been corrected from the error-prone original — there’s still plenty of work to be done.
If you’re editing transportation network data on the map, remember to check out the latest TIGER import documentation on the wiki to get a feel for how the data is tagged. It’s a fantastic data resource, but needs a fair amount of help to get up to a high standard of quality for routing.
A new Transport layer has been added as a new renderer layer to OSM. The new tiles come courtesy of Andy Allan (of OpenCycleMap) and include things like bike routes, bus routes, subways, rail systems, and train stations.
Even though the Tampa Bay Area doesn’t have quite the vibrant public transit systems of some cities, rendering data for custom use-cases like this shows the real power of the detailed data beneath the surface of OSM. It shows the value of adding things like route information, bus stops, and bike paths. You can see from the map that Tampa has pretty decent coverage of route information, while Pinellas has hardly a thing.
Last Thursday Zac threw together an unplanned OSM mapping party at the Spatial Networks office. We called in the pizza guy and hung out in our conference room, getting everyone setup to use JOSM. After a few minutes, we were all editing different pieces of the map that interested us.
We had a lot of fun indocrinating some of our fellow developers who hadn’t really committed to getting involved in OSM editing. The community continues to grow!
