Map Review Approval Number
What Is a Map Review Approval Number?
A map review approval number is a unique number granted after a map has passed technical review and administrative approval by the competent natural resources authority responsible for surveying, mapping, and geographic information before public release. It usually consists of a province abbreviation or national marker, review category code, year, and sequence number, such as Yue GS (2025) No. 001. Obtaining the approval number means the map complies with the requirements of the Regulations on Map Management, the Measures for Map Review Management, and other regulations regarding content correctness, scale accuracy, and handling of confidential information.
