This map is inteneded to show the difference between FCC Form 477 Census Block-based, and GBDI location-based data on broadband availability.
The FCC Form 477 Broadband mapping model is inherently census block resolution. This means that if the target broadband service is available to at least ONE location (residential or business) in a census block, the block appears served. Populated census blocks that did not meet this definition are delineated as 'Unserved'
The GBDI model is inherently location based. This means that the target broadband service must be available to more than 80% of locations in a census block to be served. Census blocks that did not meet this definition are delineated as 'Unserved'. The map depicts access to broadband, not subscription to broadband.
“To compile a comprehensive Master Address File by county, GBDI is requesting and collecting address data from local governments, property appraisers, e911 coordinators, and power companies. The address data will be geocoded for map address accuracy.”
“A dedicated team from the Carl Vinson Institute of Government worked for 18 months to aggregate data, develop and refine the methodology, and construct the maps. This effort would not have been possible without the support and collaboration of broadband providers. All total, 43 of 44 retail providers in the state provided data for this effort.”
