The UC Davis campus as seen in OpenStreetMap, Cycle Map

Website

OpenStreetMap.org

OpenStreetMap is a work-in-progress mapping website / interface that aims to produce an entirely free (as in speech) set of maps of the world. The maps are contributed by regular people. Unlike things like Google Maps, OpenStreetMaps are freely usable by anyone for any purpose. All the software that powers the site is freely licensed as well. For these reasons, it's been considered a potential option for wiki mapping at some point in the future (read more here if you're interested).

The mapping party was a success in that mappers showed up, braved the heat and made many edits to the map.

Who did What?

• SteveC added all of the pathways for the Arboretum and many other bike paths were improved upon. - GPS trace
  

• AlexMandel traced North UCD Campus - GPS trace
  

• BillKendrick added some missing greenbelt bikepaths, streets and footpaths in south east Davis (around here) - GPS trace

After installing mkgmap you can use the following commands to create a file than can be loaded into any Garmin GPS with a model name ending in x.

curl -g http://osmxapi.hypercube.telascience.org/api/0.5/*[bbox=-121.82,38.49,-121.67,38.59] -o data.osm 
java -Xmx512M -jar mkgmap.jar -n GMAPSUPP data.osm

Mkgmap will also allow you to combine several .osm files into one large .img file. The file that results from these commands just covers the immediate Davis area. It will have a level of detail similar to this; but you can edit and improve the map.

Alternatively you can download a weekly generated file for the entire state of California from cloudmade.com
