How we measure
- Average: every USGS 3DEP bare-earth cell of land inside the Census county boundary (TIGER/Line, Jan 1 2026), weighted equally, on a 1 arc-second (≈100 ft, 30 m) grid. Land means the boundary minus Census area water.
- Highest and lowest: the highest land cell. Lowest: the lowest land cell; coastal ground within 3 ft (1 m) of named tidal water counts as sea level.
- Nearby Places: neighboring counties and rankings use each one's average elevation, on its own grid, the same figure its page shows. Peaks and hills: the highest summits inside the county with at least 980 ft (300 m) of prominence, then the highest federal (GNIS) summits inside it when there are fewer than 5; each is the 3DEP top on a ~7 ft (2 m) window, or the NGS published height when a usable survey mark sits within 160 ft (50 m) of it (shown as published).
- Towns: each town's typical elevation (population-weighted median of its own 2020 blocks at 1 arc-second); a town is listed when any of its 2020 residents live in the county.
- Rounding: computed heights are rounded to 10 ft (5 m), or to 1 ft (1 m) under 100 ft; 3DEP is good to about a meter, not a foot. Published figures (NGS survey heights) are shown as their publisher gives them.
- Datum: North American Vertical Datum of 1988 (NAVD 88). NGS plans to replace NAVD 88 with a new datum (NAPGD2022); heights will then shift slightly.
