Tennessee location data
Isopleth answers questions about any coordinate or street address in Tennessee 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 Tennessee
Parcel records: not offered in Tennessee. Comptroller's public layer says it is not intended for commercial use (bulk download recommended for commercial purposes). Every point field on this page still works at any coordinate in Tennessee; see parcel coverage for the 35 states plus DC we cover.
Sample values in Tennessee
What our API returned at the Census Bureau's interior point of Tennessee'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.
