How we measure
- Typical elevation: the population-weighted median: every 2020 Census block inside the township boundaries, at its USGS 3DEP height, weighted by the people who live there. Half of residents live higher, half lower.
- Lowest, highest, average: USGS 3DEP bare-earth heights on a 1 arc-second (≈100 ft, 30 m) grid, land only, inside the Census township boundaries (TIGER, Jan 1 2026).
- Pits: the lowest point is the lowest ground outside closed hollows (quarry floors, mine pits, terrain-model artifacts): any hollow under 0.4 sq mi (1 km²), and any hollow under 2 sq mi (5 km²) whose floor is more than 100 ft (30 m) below its rim; and outside patches below sea level of under 0.4 sq mi (1 km²). The single lowest 3DEP cell, −190 ft at 39.9210° N, 75.4849° W, is in such a hollow or patch and is not counted.
- Nearby Places: nearby towns and rankings use each town's typical elevation, so every town is compared like for like. Rankings count every city, town, township and census-designated place, including places inside a town. Peaks and hills: the nearest summits with at least 980 ft (300 m) of prominence within 62 mi (100 km), then federal (GNIS) summits within 16 mi (25 km) 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).
- 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 (FAA airport elevation, 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.
