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 |
|---|---|---|---|---|---|
| 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 |
| AREA_KM2 | area | km2 | ha | 100 | converted |
| geometry | area / length | EPSG:4326 degrees | ha / m | — | geodesic area (ha), perimeter (m) and length (km) computed on the WGS 84 ellipsoid with PostGIS |
