NMC
The Northern Mozambique Channel is the 2nd richest in the world in terms of coral reef biodiversity, supporting 30% of global tanker traffic, rich fishing ground with tuna fisheries worth $2 billion/yr in the Western Indian Ocean a reservoir for small-scale fishers who account for 70-80% of all catches, a future major producer of natural gas, over 100 trillion cubic feet (known as of 2015) and an increasingly popular destination for coastal tourism and diving.

Unit harmonisation applied to this dataset
Every number in Atlas is stored in one canonical unit; the original value and unit are always kept
| Source field | Measure | Source unit | Atlas unit | Factor | Treatment |
|---|---|---|---|---|---|
| hectares | area | ha | ha | 1 | kept (unit taken from field name) |
| Shape_Length | area/length | unknown (often degrees) | — | — | excluded unit not stated; geodesic area/length computed from geometry instead |
| Shape_Area | area/length | unknown (often degrees) | — | — | excluded unit not stated; geodesic area/length computed from geometry instead |
| geometry | area / length | EPSG:4326 degrees | ha / m | — | geodesic area (ha), perimeter (m) and length (km) computed on the WGS 84 ellipsoid with PostGIS |
Attributes stored per feature
How many features carry each attribute (first 20,000)
| Attribute | Features |

Checked against the geometry
Source value ÷ the same quantity computed from the stored shape
