Development Corridors
33 corridor segments from Table 1 of the paper, buffered by 25km on either side of the corridor (road or rail etc.). The data fields of the corresponding .dbf file (included; you can view in it Excel if not ArcGIS) are fairly self-explanatory: ‘status’ is as per Table 1 of the paper; ‘label’ is as per Figure 3 of the paper; ‘pc_settl’ is the percentage area of each buffer zone that is settled, as indicated by nightlights, as described in the paper; ‘poly_area’ is the area (in m2) of each buffer zone; ‘green’ and ‘red’ are respectively the data defining the environmental value and agricultural

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 |
| Shape_Area | 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 |
