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.
- Area
- Fades everything outside the official reservation boundary (US Census).
Elevation Data
Chitimacha Reservation averages about 11 ft (3 m) above sea level across all its land. Its ground runs from 0 ft on the northeast side to 16 ft on the northeast side.

Chitimacha Reservation is nearly flat: its ground varies by only about 16 ft, so the figures below sit close together.
1% of Chitimacha Reservation's land lies below the average daily high tide (MHHW, NOAA), and 1% lies less than 3 ft above it. Check flood zones on FEMA's map

How we measure
- Average: every USGS 3DEP bare-earth cell of land inside the Census reservation boundary (TIGER/Line AIANNH, 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.
- 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, −2 ft at 29.8896° N, 91.5290° W, is in such a hollow or patch and is not counted.
- Name: the Census Bureau's legal or statistical area name, as published; the nation's own name may differ.
- Population: 2020 Census residents of the blocks inside the boundary.
- Nearby Places: nearest tribal lands 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 reservation 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 reservation.
- 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.
