Regional GIS Group Meeting
Wednesday, July 11th, 200710:00 AM - 1:00 PM
Duke Room – Loudermilk Center, B-Level
Cooperative Purchase Agreement
• Save money for participants• Opportunity for counties who were
unable to purchase before• Gives access to more coverage• Individual counties have paid up to
$580K
Cost
• Based on Earth Data quote• Cost: $1,390,296 or $212/square mile• Resolution: 6” pixel• Example: 20 County region• Breaks out cities separately for added
savings• Estimates of cost and methodology for
procurement of imagery may change depending on number of participants
What Next?
• Is this something we wish to consider?
• Other products to consider?• CIR/LIDAR etc.• Specifications?• What should be the next steps?
Who Collects/Creates Street Data?
• City Government
• County Government
• Regional Development Centers
• State Government
• Federal Government
•
Georgia State Law
• Local Governments are required to submit acceptance of new roads, reporting of reconstructed roads, or abandoned roads according to Georgia State Code 32-4-41(4) and 32-4-91(b) – (4) A county shall keep on file in the office of the county clerk, available
for public inspection, the map of the county road system prepared by the department as provided for in subsection (a) of Code Section 32-4-2. In addition to keeping on file a map of the county road system, the county shall notify the department within three months after a county road is added to the local road or street system and shall further notify the department within three months after a local road or street has been abandoned. This notification shall be accompanied by a map or plat depicting the location of the new or abandoned road;
• Disconnect : Data not reported regularly
Street Data Collection Objectives
• MONEY!!!$$$• Planning • Mileage • Condition• Safety and traffic flow • Cartographic needs• Network analysis• Geocoding• E911
Collection Methods
•Digitized from plats•Digitized from aerials•Digital submission•GPS•Field collection
Historical State Data Collection
• Process in 4th decade• RC data file (non-spatial) created in
1976• First DLGF map created early ’90s• No addressing, indirect street names
GDOT Data Reporting
• Need local government to report new, reconstructed, or abandoned roads
• Annual reporting of mileage & transportation data to Federal Government
• Needed to receive fair allotment of transportation funds
• Road maps for 159 counties
Collaboration
• Foster relationships with appropriate persons involving GIS data • Data sharing• Reduce data redundancy• Improve efficiency• Sharing of scripts, tools

Street Attribution
• Federal Standards – 98 • State Characteristics – 110• Local Characteristics – approx. 52• Surface type/dimensions, shoulders,
travel lanes, speed limit, sidewalks…• Already have engineering standards • Attributes tool
GDOT RC Contract
• ARC working with GDOT to improve data collection processes
• Facilitate work with local governments to collect data
• GDOT migrating existing database to more modern framework
• GDOT working to receive data via web submission from local governments
State and Regional Street Network
• Form consortium• Create unified data sharing agreement • Adopt standards due to varying levels of accuracy and quality • Data translation/ integration• Develop data model, software tools
Considerations
Other Models: Enterprise street data efforts
• Washington DOT• South Dakota DOT• SANDAG: (San Diego Association of
Governments) -Formed Streets Committee-City provides data to county, edited
in SDE directly• Mecklenburg-Union MPO:
-Formed consortium with City/County Govs.
-Digital CAD submissions required, added to SDE
