Georgia location data
Isopleth answers questions about any coordinate or street address in Georgia with 351 public-data fields from 95 sources: flood and wildfire risk, soils and slope, the power grid, water and roads, climate, and county economics. Each value carries its source, license and vintage. Use it from the REST API or through the MCP server in Claude, ChatGPT, Cursor and other assistants.
Parcel coverage in Georgia
Parcel records: 289,819 parcels in 2 of Georgia's 159 counties, loaded county by county from layers each county publishes for reuse: DeKalb (246,235), Clarke (43,584). Refreshed quarterly.
Share of parcels with each column filled: owner name 100%, site address 100%, total value 82%, zoning 48%. Not published here: land use, sale date, year built.
Sample values in Georgia
What our API returned at the Census Bureau's interior point of Georgia's 3 largest counties by land area, computed 2026-10-29. One point is not a whole county: values can change within a few hundred meters, so look up your own site. "No data" means the dataset has nothing at that point.

What people use it for in Georgia
- Land buyers: screen a lot for flood zone, wetlands, slope, soils, road and water access before a site visit; search Georgia parcels by county, acreage or land use. Buyers who want it written up can order a $29 report on Check the Land, which is built on Isopleth.
- Solar, wind and data-center siting: distance to transmission and substations, solar and wind resource, protected land.
- Insurance and lending: hazard frequencies and floodplain status for every address in a book.
- Real estate and research: county income, growth and house-price trends next to on-the-ground facts.
