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.
- Borough area
- Fades everything outside the official borough boundary (US Census).

How we measure
- Average: every USGS 3DEP bare-earth cell of land inside the Census borough boundary (TIGER/Line, Jan 1 2026), weighted equally, on a 3 arc-second (≈300 ft, 93 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; it is a named summit, so its height is the peak method: the 3DEP top on a ~7 ft (2 m) window, or the NGS published height when a survey mark sits within 160 ft (50 m) of it. 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, −4 ft at 55.3976° N, 131.4785° 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 boroughs and census areas 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 borough 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 borough.
- 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.
- Alaska: much of Alaska's 3DEP comes from airborne radar (IfSAR), good to a few meters.
- 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.
