Community Projects

The Atlanta Mapping Initiative

The Atlanta Mapping Initiative is a collaborative effort to build the map of the City of Atlanta (inside the perimeter of the city limits), with the ultimate goal of making it the most digitally mapped city in the US by January 2010. To reach this goal, the OSM community in Atlanta is partnering with universities and community groups to record points of interest, amenities and local attractions. The Initiative is scheduled to run from September 2009 to January 2010.

In addition to rapidly expanding the map of Atlanta, the Mapping Initiative is designed to build long lasting and sustainable partnerships so the map will stay up to date and accurate. These partnerships also grow and diversify the OSM community in Georgia by introducing mapping to new segments of the population and including OSM mapping in schools and universities. For more information about the organizations working with the OSM Atlanta community, please visit the PARTNERS section.

Another important facet of the Atlanta Mapping Initiative is collaboration with municipal GIS departments and working closely with them to donate and add their public geodata repositories to OSM. These donations free OSM community members so that they can focus their efforts on adding richness and detail to the map and mapping areas that have yet to be edited.

The Atlanta Mapping Initiative launched on September 12, 2009 with the Citywide Mapathon Training Event. This event was a way for new OSM mappers to learn how to map from the most experienced mappers in their area. It was also a way for the volunteers who will be helping during the Citywide Mapathon to brush up on their editing skills.

The flagship event of the Atlanta Mapping Initiative is the Atlanta Citywide Mapathon on October 16-18. This event will target the entire city and bring citizens from different neighborhood together to map Atlanta. The Mapathon stretches over three days. Day 1 will be an open forum for participants to meet and discuss how and why they are supporting OSM. It is a great way to meet people with similar hobbies, network with business leaders and collaborate with students and professors from some of the top universities in Georgia. During Day 2, mappers will target public parks, historic sites, university campuses and other areas that are open to the public. This is a great, low cost way to get out into the heart of the city, learn more about the everyday features that are often overlooked, learn about the history of Atlanta and enjoy the company of other map enthusiasts. Day 3 will be focused on mapping neighborhoods. This portion of the event is a great way make sure that residential areas have up to date maps.

Following the Mapathon, the OSM community will be holding monthly mini-mapping events.

Partner Organizations

Recently a number of high profile groups in Atlanta have become interested in supporting OpenStreetMap's mission to make an open map of the world that can be used by all. Each of these groups supports OSM for a different reason, however they all have one thing in common; they see the potential of the map and want to work together to ensure that the map of Atlanta is one of the best on the world and that OSM is used throughout the academic, business and non-profit sectors.

The groups that are partnering with OSM members in Atlanta, either by working to incorporate mapping into their regular activities or supporting the project by offering PR and logistical help, are all dedicated to one thing: making sure that Atlanta, Georgia is uniquely positioned to enter the new economy with a strong geospatial industry and workforce trained in the future of maps - OSM!

The list of groups that have teamed up with mappers to help put Atlanta on the map are:

The GeoGeorgia Initiative: The GeoGeorgia Initiative is a volunteer umbrella collaboration among Georgia Tech, University of Georgia, and other universities in Georgia. The GeoGeorgia Initiative mission is to facilitate the growth of the geospatial industry in Georgia through workforce training and the education of state and local governments to make geospatial freely available to the public.

"OpenStreetMap is the "linux" of geospatial data: it's the stuff of which the future of location-based services and analysis is made! Georgia welcomes the Atlanta Initiative to showcase how a major city can quickly get digitally mapped through a grass-roots effort," said Dr. Frank Howell, Director of the GeoGeorgia Initiative.

The Initiative organized the donation of free-available data from the Georgia GIS Clearinghouse to the OSM Atlanta Initiative. For the Atlanta Mapping Initiative and Citywide Mapathon, this group is providing public relations support and serving as a liaison to business associations and governmental departments.

For more information about the GeoGeorgia Initiative, please visit their website.

Georgia URISA: The Urban and Regional Information Systems Association (URISA) is a non-profit professional and educational association that promotes the effective and ethical use of spatial information and information technologies for the understanding and management of urban and regional systems. It is a multidisciplinary association where professionals from all parts of the spatial data community can come together and share concerns and ideas.

According to Tripp Corbin, president of Georgia URISA, "Tools like Google Earth and GPS navigation devices have made map based technology a bigger part of peoples day to day lives. This is also shown us how quickly our environment is changing with new roads, restaurants, hotels, and so on being built every day. However it takes forever for these to be added to the maps we use. Open Street Map allows users capture these changes and share them with the world so we are no longer forced to wait for updates. This promotes the use and development of spatial data and puts the power back in the hands of the users which is why Georgia URISA is a supporter of this effort."

The Technology Association of Georgia (TAG): The Technology Association of Georgia (TAG) is a non-profit organization whose mission is to support its members by generating opportunities for personal, professional and business growth. By forging strategic alliances, TAG serves as a primary catalyst to foster a rich environment for economic development in Georgia's technology community. TAG is made up of over 7,500 members representing technology leaders from over 1700 Georgia-based companies, affiliated technology and business organizations.

“The Technology Association of Georgia is proud to support this initiative as it promises to spur innovation and promote technology based economic development, while at the same time establishing Georgia as a leader in the geospatial mapping industry.” - Tino Mantella, President of TAG

The GeoTech Center: The goals of the GeoTech Center is to create a national clearinghouse of exemplary geospatial curriculum materials, resources and national services.

Increase the capacity to educate geospatial technicians through new partnerships and collaborations.

Increase the quantity, quality and diversity of geospatial technicians to meet U.S. workforce needs.

Provide a unifying voice for geospatial technology education interests in organizations, industry and government.

Increase the number of community and technical college geospatial faculty and secondary school teachers participating in geospatial professional development.

The Georgia GIS Coordinating Committee (GISCC): The GISCC was created in 1996 to lead and encourage continued development and use of the Georgia Spatial Data Infrastructure (GaSDI).

The Georgia GISCC’s vision is that all levels of government become highly effective and efficient through the coordination and use of geospatially-related data, standards and technologies. The GISCC’s mission is to be a valued advisor on sustainable geospatial governance, investments, policies and data-driven decisions influencing Georgia.

The GIS Clearinghouse serves as the implementation arm of the GISCC and Georgia’s data/metadata feed to the National Spatial Data Infrastructure (NSDI): The Clearinghouse serves over 30,000 geospatial assets through its web interface. The Clearinghouse has over 28,000 registered users at an average of approximately 400 new users per month (2009 stats).

For more information about the GISCC, please visit their website. [5]

The Gainesville State College Geospatial Alliance: The GSC Geospatial Alliance is a campus club that participates in geospatial and environmental activities that benefit the community and university. This organization is currently working to upload the GIS data from GSC campus and the surrounding area. The students and faculty advisors are also participating in the Atlanta Mapping Initiative by helping upload data gathered by citizen mappers and checking the accuracy of the data collected.

Tiger Corrections

The TIGER Data for the Atlanta area is mostly quite good. However, there is still TIGER fixup to be done. You can help!


Interstates and other limited access highways need work to correct the following:

  • Interstates themselves need to have the ways point in the right direction, and be given oneway and ref tags.
  • The Tiger import created intersections between interstates and any ways that cross them. These intersections need to be removed.
  • Ramps need to be oriented in the right direction and marked as one-way.
  • Ramps sometimes need to be untangled - the TIGER data may combine parts of two ramps that cross on different levels to create a single way. This is only an issue in more complicated intersections.
  • It is helpful to remove the Tiger_Reviewed tags to show that the way has been corrected

These changes are especially important to make routing work correctly in the Atlanta area.

The following interstates have been completed

Please update these notations as you fix the interstates

  • I-285 and all interstates inside the perimeter
  • I-75 North to end, South to Gainsville, FL
  • I-575 North to end
  • GA-400 North to end
  • I-85 North to SC Border
  • I-985 North to end
  • US-78 East to end of limited access
  • I-20 East in to the Morgan County line
  • I-675 South to end
  • I-75 South to Monroe County line
  • I-85 South to I-185
  • I-20 West to Douglasville

County Boundaries

Main article: Georgia_(U.S._state)/County_Boundary_Relations

The tiger import does not correctly stitch together the ways at county boundaries. It is therefore necessary to manually follow the boundary and connect each way that crosses the boundary. This is very important for routing across county lines.

Counties with bad Tiger Data

Some exurban counties have bad tiger data which needs heavy editing, and even replacing by hand in many cases. These include:

  • Bartow
  • Spalding
  • Monroe
  • Butts
  • Haralson

In some cases, the more recent TIGER data is markedly improved, and can replace the older data. See: Georgia (U.S. state)#Tiger.

One Way Streets

The tiger data does not indicate which streets are one way. As this can not be determined via aerial images, either, there is no substitute for on-the-ground observation and personal knowledge in providing this information.


Some extensive work has been done on waterways in the Atlanta region. However, a future import of the National Hydrography Dataset should make it unnecessary to add the waterways manually.

Missing Data

Some ways, especially newer roads are missing from the TIGER data and need to be added by hand.

Institutions and Points of Interest

Many remain to be done, including:

  • King Center
  • Oglethorpe University
  • Kennesaw State University
  • and many others

Public Transit

When adding and maintaining Atlanta area public transit in OpenStreetMap, please refer and update these pages of existing relations.

Data Sources

There are some potential data sources for Atlanta that could be imported.

  • Fulton County has an excellent GIS system, available on-line at: [6]. However, it is unclear if the data is available under a license compatible with Openstreetmap. Presumably, other metro counties have similar GIS info.
  • The ARC has a number of datasets available on-line at: [7]. Again, more research would be needed on the license.


The ARC has given us permission to import their LandPro08 database, which has good, up-to-date land use info for the Atlanta region.
