How to use this mapviews, tools and data
- Elevation
- Ground colored by height from green (lowest) to white (highest), with contour lines every 40–500 ft (USGS data).
- Satellite
- A 2016 satellite photo at 33 ft (10 m) detail; contours off.
- 3D
- Tilt and turn the terrain; hills are raised 1.5×, or set ×1 for true height.
- Click or tap anywhere
- The exact elevation of that spot in ft and m.
- Measure
- Pick two points for the climb, descent and grade along a straight line.
- State area
- Fades everything outside the official state boundary (US Census).
Elevation Data
Delaware averages about 48 ft (15 m) above sea level across all its land. Its ground runs from sea level on Delaware Bay to 450 ft on the north side.

Delaware spans about 450 ft of height, so no single spot tells the whole story. The ruler shows where most of its land lies, and where the other numbers you'll see come from.

How we measure
- Average: every USGS 3DEP bare-earth cell of land inside the Census state boundary (TIGER/Line, Jan 1 2026), weighted equally, on a 2 arc-second (≈200 ft, 62 m) grid, coarsened from 1 arc-second so the whole area fits one run. Land means the boundary minus Census area water (on this grid, water areas of at least half a cell).
- Highest and lowest: the highest land cell, re-read at 1 arc-second around the 25 highest grid cells. Lowest: the lowest land cell, re-read at 1 arc-second around the 25 lowest grid cells; coastal ground within 3 ft (1 m) of named tidal water counts as sea level.
- 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, −3 ft at 39.2560° N, 75.4068° W, is in such a hollow or patch and is not counted; this coastal land's lowest point is sea level on the coast.
- Nearby Places: neighboring states 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 state 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).
- Counties: each one's average on its own grid (1 arc-second, coarser for the largest), the same figure its own page shows.
- 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.
