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 |
|---|---|---|---|---|---|
| st_length(shape) / shape_leng | length | degrees (EPSG:4326) | — | — | excluded degrees; replaced by length_km 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 |
|---|---|
| tag_id | 7 |
| track_date_utc | 7 |
| length_km | 7 |
Checked against the geometry
Source value ÷ the same quantity computed from the stored shape
