m spread (p95−p5, ~20–40 km window)

The county center sits at about 295 m above sea level. Elevation across the sampled window spreads 79 m — gently rolling terrain by our banding (flat <30 m · gently rolling 30–100 m · hilly 100–300 m · mountainous >300 m). These are county-scale context, not parcel measurements — a specific parcel gets its own slope, flood and usable-acreage readings when analyzed.

Elevation measured 2026-07-21 from the AWS Terrain Tiles (terrarium encoding, z10).

Data available for Green County

  • Owner of record, parcel number, assessed value and the county's parcel boundaryWisconsin publishes these as open data (Wisconsin Statewide Parcel Map Initiative). LandBenchmark reads them directly.
  • Legal description — township, range and section from the BLM Public Land Survey System.
  • FEMA flood zones, wetlands, soil survey and NCCPI soil productivity — the federal layers, all free and all available here.
  • 56 measured signals from satellite imagery and public records — slope and usable acreage, observed surface water, vegetation trend, wildfire and seismic hazard, access and neighboring land use. Each one cites its method, its source, and the date it was observed.

LandBenchmark has no listings and does not know what is for sale in Green County. It analyses a parcel you point it at. It is an automated Phase-1 desk screen, not a survey, a flood determination, or a substitute for on-site inspection.

Common questions about land in Green County

Can I see who owns a parcel in Green County?

Yes — Wisconsin publishes parcel ownership as open data (Wisconsin Statewide Parcel Map Initiative), so a LandBenchmark report on a Green County parcel shows the owner of record, parcel number and assessed value, cited to the state dataset.

How hilly is Green County?

Around the county center, measured elevation spreads 79 m across a ~20–40 km window — gently rolling terrain by our banding. Individual parcels vary: a report measures the actual slope and usable acreage of the parcel you point it at.

What can LandBenchmark measure for a parcel in Green County?

56 measured signals, each cited with source and observation date: FEMA flood zone plus surface water observed in multi-year imagery, USFWS wetlands, USDA soil survey and productivity, slope and usable acreage, wildfire and seismic hazard, access and surroundings. What a satellite cannot verify — title, zoning, perc results, water rights — goes on a human-verify checklist naming the Green County offices that can.
