| Administrative levels in boundary polygon shapefile | Required new fields in boundary polyline shapefile |
|---|---|
| Administrative level 0 | AdmLevel (integer) |
| Administrative levels 0 and 1 | LEFT_A0, RIGHT_A0 (normally text) AdmLevel (integer) |
| Administrative levels 0, 1, and 2 | LEFT_A1, LEFT_A0, RIGHT_A0, RIGHT_A1 (normally text) AdmLevel (integer) |
| Administrative levels 0, 1, 2, and 3 | LEFT_A2, LEFT_A1, LEFT_A0, RIGHT_A0, RIGHT_A1, RIGHT_A2 (normally text) AdmLevel (integer) |
Note that in the unusual case of numeric P-codes, the new fields should be of the same type. These fields can be removed after the process is complete, so their names do not have to be those shown.
- Verify that the AdmLevel values have all been set to zero. Calculate them to zero if they are not.
