Measurements recorded
Geometry-only dataset
No separate measurements; attributes are shown in the data table.
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 |
|---|---|---|---|---|---|
| area_ha | area | ha | ha | 1 | kept (source value) |
| shape_leng | length | m | m | 1 | kept; verified against geometry perimeter |
| st_area(shape) | area | square degrees (EPSG:4326) | — | — | excluded not a physical area; replaced by area_ha_geodesic computed from geometry |
| st_length(shape) | length | degrees (EPSG:4326) | — | — | excluded not a physical length; replaced by perimeter_m computed from geometry |
| (computed) area_ha_geodesic | area | geometry | ha | — | ellipsoidal area of the stored geometry (WGS 84), computed by PostGIS |
| (computed) perimeter_m / length_km | length | geometry | m / km | — | ellipsoidal perimeter (m) or line length (km), computed by PostGIS |
Attributes stored per feature
How many features carry each attribute (first 20,000)
| Attribute | Features |
|---|---|
| area_ha_geodesic | 7 |
| perimeter_m | 7 |
Checked against the geometry
Source value ÷ the same quantity computed from the stored shape

Atlas serves this dataset from its own archived copy. Nothing is requested from the publisher when you view or download it.
Verification against the raw archive
Record counts match the source
Imported record count equals the source's own count; per-record cross-check recorded in the import run.
