In order to strengthen the security protection of geographic information data, promote the circulation, trading, and development of geographic information data, the Ministry of Natural Resources recently issued the "Guidelines for Classification and Grading of Geographic Information Data (Trial)" (hereinafter referred to as the "Guidelines").
Data classification and grading are the prerequisites and foundations for carrying out geographic information data governance, realizing the protection of the entire process of data collection, aggregation, processing, circulation and trading, sharing and utilization. The formulation and implementation of the "Guidelines" are conducive to understanding the important and core data base of industry geographic information, providing a basis for strengthening the security of the entire lifecycle of geographic information data and coordinating the implementation of data differentiation security protection. At the same time, it also helps to promote the classification, grading, authorization, use, and circulation of geographic information data, orderly expand the supply of geographic information data elements, and fully play the role of surveying and mapping geographic information data element protection.
The main content of the Guide includes four aspects. One is to clarify the basic principles of geographic information data classification and grading. The Guidelines require that the principles of "scientific practicality, comprehensive judgment, and dynamic updating" should be followed in all aspects of data classification, data grading, directory management, and updates. The second is to determine the data classification rules. The "Guidelines" classify geographic information data into three categories: basic geographic information data, remote sensing image data, and thematic geographic information data. Within each category, several subcategories are further subdivided, and the classification can be further refined based on actual data management and application service scenarios. Thirdly, propose data grading rules. The "Guidelines" establish grading rules for identifying factors in the classification of geographic information data, conducting data impact analysis, and comprehensive evaluation grading, while also providing criteria for identifying important and core data. Fourthly, clarify the requirements for classification and grading management. The "Guidelines" stipulate the relevant work procedures for the declaration, review, and recognition of important geographic information data catalogs, as well as several requirements for dynamic updates and update management.
It is understood that the classification and grading of geographic information data is a supplement and extension of the existing classification and grading of natural resource government data. The "Guidelines" have maintained a connection with the classification and grading of natural resource government data in terms of data classification, and have refined geographic information data in terms of data grading. In terms of scope of application, the Guidelines are mainly used by provincial natural resources authorities to guide local surveying and mapping qualification units to carry out geographic information data classification and grading work in accordance with the requirements of the Guidelines. In terms of important data protection, follow the relevant provisions of the "Management Measures for Data Security in the Field of Natural Resources".
Next, the Ministry of Natural Resources will strengthen the interpretation and training of the "Guidelines", develop an important data directory system, and achieve one-stop application, review, query, retrieval, and update of the national geographic information important data directory.
