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 |
|---|---|---|---|---|---|
| cover_perc | percent | % | % | 1 | kept when 0-100; values above 100 are impossible as a percentage and are rejected (original retained) |
| latitude_y / longitude_ | coordinate | decimal degrees | EPSG:4326 | 1 | cross-checked against point geometry |
