Sample values in Nebraska
What our API returned at the Census Bureau's interior point of Nebraska'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 Nebraska
- Land buyers: screen a lot for flood zone, wetlands, slope, soils, road and water access before a site visit; search Nebraska 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.
