Description: 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 potential columns from Table 1 of the paper, which re-scale these data, as described in paper.
