How to edit the digital commune-level administrative boundary map? (Illustrative image)

Circular 48/2014/TT-BTNMT stipulates the editing of the digital commune-level administrative boundary map as follows:

- The editing of the digital commune-level administrative boundary map must comply with the current regulations on editing digital topographic maps of the same scale, with the addition of administrative boundary elements to the group of border and boundary objects. These administrative boundary elements must be represented digitally as regulated in this Circular;- Administrative boundary elements are organized and separated into distinct layers and edited according to commune-level administrative units. Other geographical elements remain as per the base map fragments;- In case of conflicts regarding the position of administrative boundary markers compared to nearby geographical elements, the geographical elements on the map must be re-edited accordingly;- In areas with a dense density of geographical features, when administrative boundary markers or distinctive points coincide with geographical elements on the map, priority is given to representing boundary elements, geographical elements described in the administrative boundary, and nearby geographical elements serving as orientation;- If the administrative boundary line coincides with a linear object on the map, based on the description, standardize the linear object and related objects according to the correct geometric correlation while retaining boundary markers and distinctive points. After standardization, the administrative boundary line object must be copied to coincide exactly with the linear object;- Each administrative boundary line object must be a continuous line (Linestring) or comprise multiple connected segments with a tolerance of 0.001m. Where administrative boundaries at different levels coincide, they must be represented fully by copying to align exactly;- When editing the digital administrative boundary map, it is permissible to use automatic cleaning tools with a tolerance of 0.001m for administrative boundary markers, distinctive points on the boundary lines, and intersection points between boundary lines; 0.1m for other objects.

Detail information is available at Circular 48/2014/TT-BTNMT effective from November 03, 2014.
