The Ministry of Agriculture and Environment has issued Circular No. 24 amending and supplementing a number of articles of circulars in the field of surveying, mapping and geographic information. Accordingly, the central meridian of the map of 34 provinces and cities has also been issued.

Each province or city will have an axis meridian, selected based on the geographical location and survey and measurement characteristics of that area.

The central meridian of the map of 34 provinces and cities is the line chosen as the main landmark to determine the geographical coordinates of each area. Each province and city will have a central meridian, selected based on the geographical location and surveying characteristics of that area. The coordinate meridian, including longitude and latitude, plays an important role in determining the exact location of any location on earth, helping to locate, measure, and map effectively.
