SGR Alignment
This data was received from the Kenya Railways Corporation. Adjustments at the Nairobi area crossing the Nairobi National Park generatede by WWF - Kenya by digitizing adopted routing options by Kenya Railways Corporation. It is shared with Sight Africa inorder to reflect on the routing changes by SGR and help inform analysis along the major development corridors.

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 |
| geometry | area / length | EPSG:4326 degrees | ha / m | — | geodesic area (ha), perimeter (m) and length (km) computed on the WGS 84 ellipsoid with PostGIS |
Attributes stored per feature
