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 fieldMeasureSource unitAtlas unitFactorTreatment
st_length(shape) / shape_lenglengthdegrees (EPSG:4326)——excluded degrees; replaced by length_km computed from geometry
(computed) area_ha_geodesicareageometryha—ellipsoidal area of the stored geometry (WGS 84), computed by PostGIS
(computed) perimeter_m / length_kmlengthgeometrym / km—ellipsoidal perimeter (m) or line length (km), computed by PostGIS
