Point LandBenchmark at any parcel — draw the boundary or pick it from county records — and it returns a green / caution / walk-away verdict in about a minute, built from up to 56 measured checks on US parcels (36 anywhere on Earth): FEMA flood zone and surface water actually observed across years of satellite imagery, USFWS wetlands, USDA soil survey and soil productivity, slope and usable acreage from elevation models, wildfire and seismic hazard, access and surroundings. Every value cites its source and observation date, and anything a satellite cannot verify — title, zoning, perc tests, water rights — goes on a human-verify checklist instead of being guessed.
