- Click ‘OK’
- Open the output polyline shapefile attribute table
- Use the Field Calculator to calculate all the LEFT_Ax values (for the LEFT_Ax files recently added to the polyline shapefile) equal to the corresponding administrative levels of the polygon shapefile. (ArcGIS may require you to begin an edit session.)
| Administrative levels in boundary polygon shapefile | Required calculations |
|---|---|
| Administrative levels 0 and 1 | polyline shapefile 'LEFT_A'0 = polygon shapefile 'ADM0_PCODE' |
| Administrative levels 0, 1, and 2 | polyline shapefile 'LEFT_A0' = polygon shapefile 'ADM0_PCODE' polyline shapefile 'LEFT_A1' = polygon shapefile 'ADM1_PCODE' |
| Administrative levels 0, 1, 2, and 3 | polyline shapefile 'LEFT_A0' = polygon shapefile 'ADM0_PCODE' polyline shapefile 'LEFT_A1' = polygon shapefile 'ADM1_PCODE' polyline shapefile 'LEFT_A2' = polygon shapefile 'ADM2_PCODE' |
