m spread (p95−p5, ~20–40 km window)

The county center sits at about 1,021 m above sea level. Elevation across the sampled window spreads 187 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 Armstrong County

• Owner of record, parcel number, assessed value and the county's parcel boundary — Texas publishes these as open data (Texas Geographic Information Office — StratMap Parcels). LandBenchmark reads them directly.
• No township/range legal description. Texas is a metes-and-bounds state with no PLSS grid.
• 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 Armstrong 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.
