Circular 48/2014/TT-BTNMT stipulates that the coordinate tables of administrative boundary markers and characteristic points on the district-level and provincial-level administrative boundary lines are established based on the coordinate confirmation tables of the commune-level administrative boundary markers in Vietnam. To be specific:

- Commune-level administrative boundary markers on the district-level administrative boundary line and intersections between commune-level administrative boundary lines and district-level administrative boundary lines where markers are not placed are considered characteristic points on the district-level administrative boundary line;

- District-level administrative boundary markers on the provincial-level administrative boundary line and intersections between district-level administrative boundary lines and provincial-level administrative boundary lines where markers are not placed are considered characteristic points on the provincial-level administrative boundary line.

In cases where the coordinate system of the commune-level administrative boundary map differs from that of the district-level and provincial-level maps, the coordinate values must be converted to match the coordinate system of the district-level and provincial-level maps.

The coordinate tables of administrative boundary markers and characteristic points on the district-level and provincial-level administrative boundary lines are prepared as prescribed in Appendix 06 issued with this Circular. Coordinate and altitude values are accurate to 0.01m.

For further details, refer to Circular 48/2014/TT-BTNMT, which comes into effect in Vietnam from November 3, 2014.
