OpenStreetMap Groups across United States Rally for Jan. 26 “Edit-a-Thon”

Open-source mapping project schedules another of its popular map marathons

WASHINGTON, D.C.-Jan. 21, 2013-The U.S. chapter of OpenStreetMap (OSM), the worldwide open-source mapping project, will hold another of its popular mapping marathons, called an "Edit-a-thon," on January 26, 2013.
Groups across the country have signed up, including mapping parties to be held in San Francisco, Calif., (, Sunnyvale, Calif., (,  Washington, D.C., Seattle, Wash, and Tampa Bay, Fla. ( In addition, numerous smaller groups nationwide plan to participate.
Open is a global volunteer effort to create a free and open map of the world. The project has more than 900,000 contributors working around the Earth. OSM has developed sophisticated software and easy-to-use mapping interfaces that enable all kinds of mappers, from first-timers to experienced professionals, to contribute.
The groups will begin work at 12 noon, EST, and are expected to continue until at least 6 p.m. that evening. 
The goal will be to improve the United States map in specific ways. Groups are encouraged the begin by concentrating on their home towns, aligning streets to the satellite imagery from Bing ( used by OSM and adding information about roads, such as number of lanes and whether they are paved.
Beyond the basics, mappers will be working to add such extras as speed limits and turn restrictions, so the map data can be used for automobile navigation. And, they hope to enrich the map even further with data, such as stores, restaurants, schools and libraries.
The US Chapter of OpenStreetMap is grateful to those who are providing meeting locations for this weekend's mapping events. These include, at presstime,

About (OSM) creates and provides free geographic data, such as street maps, for anyone to use. Most maps considered "free" actually have legal or technical restrictions that hold back their use in new creative or productive ways.
OpenStreetMap launched in the fall of 2004 in London. Since then the organization has grown to more than 500,000 volunteer members worldwide. Almost daily there are meetings and new projects initiated by OSM members worldwide. In January of 2010, OSM started a special project to provide critical mapping data to support the emergency efforts following the earthquake in Haiti, a project that continues today. And, after the March 2011 tsunami in Japan OSM stepped in again to provide critical mapping data to emergency responders and government organizations.
