There was a massive three day mapping event: Atlanta Citywide Mapathon in October 2009.

FOX News Atlanta TV report!

Since then the mapping community here continue to make progress. Contact the OpenStreetMap community if you need help with learning how to edit the map to input your data.

Other mapping parties?

If you would like to organize a neighborhood Mapping Party in your community, go ahead and do it! Feel free to contact Thea Clay who is on hand to give help or advice.

Tagging Guidelines for Georgia

Highway Classification

It is recommended that the Highway Functional Classification System maps created by GADOT be utilized so that there is consistent classification of roads across the state.
Further information:Highway Functional Classification System
Further information:Key:highway
Further information:United States roads tagging

Key Value HFCS Value Description Examples
highway motorway
  • Rural Interstates
  • Urban Interstates
  • Other Freeways & Expressways
Interstate highways, including loops and spurs; significant portions of US and state routes built to Interstate standards (high-speed, fully access-controlled).
  • Rural Principal Arterials excluding Interstates
Selected U.S. and state routes not built to Interstate standards. High-speed highways, sometimes divided with limited-access. May have occasional traffic lights and unlit street-level crossings.
  • Rural Minor Arterial Road
  • Urban Principle Arterials excluding Interstates and Other Freeways & Expressways
Major U.S. and state routes, such as those that link cities and larger towns and other traffic generators, such as major resort areas, that are capable of attracting travel over similarly long distances and form an integrated network providing interstate and intercounty service. These routes have relatively high overall travel speeds and minimum interference to through traffic. In urban areas, these highways serve the major traffic movements connecting central business districts, outlying residential areas, major intercity communities, and major suburban centers. They serve a major portion of the trips entering and leaving the urban area, as well as the majority of the through traffic desiring to bypass the central city.
  • US 78 in Atlanta
  • GA 166 in western Douglas and eastern Carroll Counties
  • Rural Major Collector Roads
  • Urban Minor Arterial Streets
Other U.S. and state routes, major county and city streets; Serve trips of moderate length at a somewhat lower level of travel mobility than principal arterials (primary highways). Provide access to geographic areas smaller than those served by the higher system. Provide intracommunity continuity but do not penetrate identifiable neighborhoods. In a rural setting, these roads provide service to any county seat not on an arterial route, to the larger towns not directly served by the higher systems, and to other traffic generators of equivalent intracounty importance, such as consolidated schools, shipping points, county parks, important mining and agricultural areas, etc, and link these places with nearby larger towns or cities, or with routes of higher classification. They serve the more important intracounty travel.
  • 10th Street
  • 14th Street
  • Auburn Ave
  • Edgewood Ave, in Atlanta
  • Austell Rd.
  • US 41 in Cobb County
  • Braswell Mountain Rd in north Paulding County
  • Rural Minor Collector Roads
  • Urban Collector Streets
County, city routes, and other major local roads. These collect traffic from local streets in residential neighborhoods and channels it into the arterial system. Provide both land access service and traffic circulation within commercial areas, industrial areas, and residential neighborhoods. Provide service to remaining smaller rural communities.
  • Simpson Rd
  • Highland Ave in Atlanta
  • Hog Mountain Rd. in Oconee County
unclassified Rural Local Roads Rural or non residential roads, serve primarily to provide access to adjacent land with little to no value as through routes.
residential Urban Local Streets City/neighborhood streets not qualifying as tertiary or higher, or rural roads which have become lined with houses. Provide direct access to land and to higher road systems. Through traffic usage is discouraged.

Avoid upgrading and downgrading roads over short distances (a few miles) where they may leave and enter an urban area. However, roads can and do change class type as they enter or leave urban and rural areas or intersect with other roads.

Key Value Description Examples
ref I ## Interstate highways. I 75
I 285
US ## US highways. US 441
SR ##
GA ##
US:GA ##
State routes. The shorter forms are more likely to be rendered in Mapnik. While the US:GA form is specific, it doesn't look great on maps or in directions, and that specificity can also be accomplished using route relations. GA 400

Max Speed

~km/h 8 16 24 32 40 48 56 64 72 80 88 96 104 112 120 128

Tag what you see the actual speed limit is on the road and not a guess based on the road type. Values are assumed to be in kilometres per hour (km/h) unless units are explicit. E.g. a speed limit of 30 miles per hour should be tagged as "30 mph".

Land Use

Land Use data for Georgia from the USGS Land Use / Land Cover dataset [1] has been uploaded to the OSM server. The data has some deficiencies: it is dated, of limited resolution and, in some places, is offset from reality. It can also be awkward to edit. Feel free to delete it in your area and add land use data from scratch if that is easier to do. In metro Atlanta the ARC LandPro08 dataset has replaced the LULC dataset.

Data Sources

A number of Potential Datasources exist for Georgia.


Most of the road data in Georgia was uploaded through the Tiger upload process in 200?. For some counties, the TIGER 2007 and TIGER 2008 data is better and can replace the older data. For all counties, address information can be uploaded. For information on the status of the update see: Georgia Tiger Update.

To Do

  • All relations.
  • Connect roads/railways/utilities at county boundaries.
  • Classify roads
  • Add key:ref to US/state roads.
  • Remove duplicate roads that run along county boundaries.
  • Fix the Chattahoochee river. Currently broken south of columbus
  • Import relevant datasets from GIS Clearinghouse (eg state/fed parks).
