m spread (p95−p5, ~20–40 km window)

The county center sits at about 269 m above sea level. Elevation across the sampled window spreads 156 m — hilly 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 Dearborn County

  • No free owner records. Indiana does not publish a free statewide parcel-and-owner dataset, so LandBenchmark cannot show who owns a parcel in Dearborn County. The county assessor's office is the authoritative source. Every measured signal below is unaffected.
  • 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 Dearborn 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 Dearborn County

Can I see who owns a parcel in Dearborn County?

Not from free data — Indiana does not publish a free statewide parcel-ownership dataset, and LandBenchmark does not buy broker data. The Dearborn County assessor's office is the authoritative source; every measured signal is unaffected.

How hilly is Dearborn County?

Around the county center, measured elevation spreads 156 m across a ~20–40 km window — hilly 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 Dearborn 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 Dearborn County offices that can.
