Since the promulgation and implementation of the Regulations on the Management of Geological Data, in order to give full play to the value of geological data and improve the utilization service of geological data to the society in a timely manner according to law, according to the deployment of the Notice of the Ministry of Land and Resources and the State Secrecy Bureau on Cleaning up Classified Geological Data (No.314 [2006] of the Ministry of Land and Resources), all provincial geological data exchange institutions in China have carried out the work of cleaning up classified geological data.
1 cleanup appraisal team
Due to the complex composition of geological data, firstly, there are many kinds of geological data. Up to now, there are about 170 kinds of minerals discovered in China, so there are many kinds of geological data. Second, the contents of geological data are diverse. Geological data are not only geological elements, but also achievements in land resources, surveying and mapping, ocean, nuclear industry and environmental protection, mainly surveying and mapping data, whose elements involve state secrets such as national coordinates, elevation, gravity and military facilities. Therefore, the cleaning of classified geological data is a policy, technical and rigorous work. In order to ensure the cleaning quality of classified geological data, all factors should be fully considered when the cleaning appraisal team is formed, and personnel with various professional specialties should be selected to participate, and pilot projects should be carried out before formal work, so as to gain experience, reach a consensus and realize unified operation.
2. Solutions to specific problems.
(1) Making of cleaning registration form. Before cleaning up the registered geological data, whether the design of the registration form is complete and scientific is directly related to the efficiency of data cleaning, which can avoid unnecessary repetition and rework. Our approach is: firstly, according to the requirements of cleaning identification, design the template of cleaning registration form, page by page, write a small program on the basis of the original geological data directory database, and directly import the basic information data items needed in cleaning registration form from the directory database into the registration form, and print them out to form a cleaning registration form manuscript. This reduces the workload of manually filling in basic information, reduces errors, saves paper, reduces work intensity and improves work efficiency.
(2) Simplify the filling of the identity certificate registration form. Before the clean-up appraisal work is carried out, organize the personnel of the clean-up appraisal team to carefully study the classified categories and classified matters listed in Annex 4, and strive to understand them thoroughly. At the same time, they are familiar with the pattern that each geological data basically consists of six categories: text, approval, drawings, schedules and attachments. Then according to the collection file number (Daliu serial number), refer to "Annex 4" to clean up the physical parts one by one, and classify and define them to the file level. You don't need to fill in the appraisal results of the whole material, just fill in the classification category number and classification item number on the pre-printed registration form. It is worth noting that the logo of the attached drawing should be filled in: first, you don't need to fill in the name of the attached drawing, just fill in the number of the attached drawing; Second, before the work begins, everyone should agree whether to fill in the drawing number or the sequence number of the attached drawings; Third, list the attached drawings with the same scale to avoid confusion in future time checking. Finally, the registration form that has been cleared and identified is bound into a book, which not only saves the writing of words, but also facilitates the subsequent entry and database construction.
(3) The results of geological work are mostly expressed on the basis of topographic maps of various scales, so maps account for a large part of the amount of classified information cleaning. Grasp the attached drawings, and clean up the key points of confidential information identification. Please ask surveying and mapping experts or professionals to clearly identify the team members before cleaning up and identifying them. What are the national grade triangles and elevation points? What are independent coordinates? What is a topographic map? It is necessary to briefly explain the basic knowledge such as gravity, which can avoid and reduce the confusion of decision-making difficulties caused by cleaning up the appraisal work, increase the accuracy of appraisal and improve work efficiency. Handling of binding drawings: (1) For an atlas that only occupies a sequence number in the sequence of the whole set of drawings, we regard the atlas as a piece to identify whether it is classified or not, because the binding drawings are generally the same kind of drawings, such as tunnel plan or borehole histogram. , involving a small area, most of the scales are the same and there are no coordinates, and there are few classifications; (2) For the photo album in which each picture occupies a serial number in the whole group of picture sequences, each picture in the photo album is taken as a picture to identify whether it is classified or not. When it is uncertain whether some maps are national coordinates or national elevations, it is best to refer to the survey chapter in the text report.
(4) For the identification of classified documents, first of all, it is necessary to determine whether there are special minerals or articles about special minerals. If there are, the classified documents shall be identified according to (Huan Han [1989] No.283). For other survey data, focus on the survey chapter in this paper, and the situation is as follows: ① Mainly understand whether the survey in the exploration area refers to the national geodetic coordinates and national elevation points. If yes, it can be judged that a series of maps with coordinates, such as topographic and geological maps and comprehensive geomorphological maps of mining areas, are official national coordinate maps. As long as the scale conditions are met and the area conditions are met, they can be classified; (2) If the survey in the exploration area involves national geodetic coordinates and national elevation points, the survey starting point results table or control point results table (partially expressed in words) will generally be listed in the written report or schedule or attachment, and the results table shall be kept confidential. (3) Geological data that have been clearly defined as independent coordinates, such as attached drawings, schedules, and attachments including control point results tables, can be kept confidential, but it is necessary to consult the written reports, especially the measurement chapters in the written reports of large mining areas, to see whether there is a conversion relationship between independent coordinates and national coordinate systems, such as conversion formulas, vertical and horizontal coordinate translation parameters, coordinate rotation parameters and descriptions. If there is such a conversion relationship, it must be kept secret. If the text is bound with the approval document, the text should be regarded as a whole to identify whether it is confidential.
(5) Geological data related to uranium and thorium shall be cleared in strict accordance with the Provisions on the Specific Scope of State Secrets and Their Classification in the Nuclear Industry (No.283 [1989]). For various large-scale (1:more than 2000) drawings of uranium geological data, although the classification is not carried out according to the provisions of the Catalogue of State Secrets of Surveying and Mapping Work (National Surveying Office [2003]17), if the drawings involve uranium industrial reserve, we will still strictly follow the (Nuclear Engineering Office [197).
(6) Handling of old and new classifications. The determination of the original classification is based on the principle of reflecting the original appearance of the data as much as possible. For the data in the original small library (secret library), if the cover of the data body is not stamped with the secret seal, the following methods are adopted: ① The original secret classification of data involving uranium and thorium is determined as secret; (2) The rest of the mineral information was initially classified as confidential. However, regardless of the original classification level, the new classification level will be re-identified and classified according to the "Annex 4" standard.
(7) Data damage cleaning and warehousing can be combined with the work of checking the damage and fuzziness of collected geological data, and registration can be carried out at the same time. It provides a basis for making data recovery plans in the future and makes basic preparations for related work. In the work of cleaning up and storing classified data, we adopted the method of complete entry case by case, regardless of whether the data is classified or not, and established the file-level directory database of geological data collected in the whole province, which laid the foundation for realizing computer file-level management in the future.
For the integrity of the work, we also re-encrypted some exploration data related to marine geology, topography and marine petroleum geology, but the classification of this part of geological data should be based on the classification determined by the Marine Department of China Geological Survey and Guangzhou Marine Geological Survey.
3 comments and suggestions
(1) Through this classified data cleaning, it is found that among the geological data in the collection, the classification rate of important and highly utilized data is very high, and the purpose of data collection and management is to use them. In order to serve the society better and safer, it is hoped that the Ministry of Land and Resources will introduce the operation methods for the management and utilization of classified geological data as soon as possible.
(2) It is suggested that the minimum unit for clearing and identifying classified data, rather than the number of pages, should be stipulated uniformly, and only the number of pages can be found when actually managing and counting the number of classified data. It is impossible to say that there are few classified geological data in our library.
(3) In the input, when a set of data has no words but only pictures, it is impossible to save the description in the remarks column of the words, so it is suggested to improve the software.
(4) When multiple computers enter at the same time, the original security fence can't be saved, and it can only be saved by the server.
