In this paper, the integrity, quality, classification of results data, the necessity of correctly compiling results data according to format requirements, the problems easily occurring in electronic documents of drawings, the inconsistency between paper documents and electronic documents, and the security of electronic documents are expounded, and the countermeasures for further improving the collection of results geological data are put forward.
Keywords:: Countermeasures for the problem of intersection of geological data.
The geological data of achievements is an important record of the achievements of geological work and the main basis for the investigation, planning, management, protection and rational utilization of mineral resources. It is widely used in all aspects of social development and economic construction, such as urban construction, disaster prevention and mitigation, mineral resources exploration and development. In order to further improve the electronic submission system of geological data and improve the management and service level of digital geological data, the Ministry of Land and Resources revised and improved the requirements for electronic submission of geological data (for trial implementation) promulgated in 2002. The Format Requirements for Electronic Documents of Geological Data (hereinafter referred to as the Format Requirements) was issued in the document No.210. From April 2007, the geological data submitted must be submitted in strict accordance with the format requirements.
1 Main problems in the submission of geological data.
The integrity of geological data is 1. 1.
When submitting the geological data of the project, most projects think that it is only necessary to submit the final report, drawings, schedules and attachments of the project. However, according to the format requirements, documents must also be submitted (such as annual task book, design approval opinions, on-site acceptance opinions, workload change reply opinions, etc.); (2) "review documents (such as review opinions and review opinions)"; ③ Catalogue of Geological Archives; ④ List of physical geological data; ⑤ Registration Form for Confidentiality of Geological Data; ⑥ Registration Form of Geological Data Electronic Documents; ⑦ "External label of carrier"; ⑧ "Database and software".
The integrity of geological data collected in this project is poor. Must be repeatedly reminded and checked by the data management personnel. Therefore, when submitting the geological data of the project, the data management personnel should check whether the submitted results are complete according to the requirements of the task book and the contents of the technical documents submitted in the review opinions, and also check whether the corresponding documents are submitted according to the classification requirements of the format requirements.
In addition, when the drawings made by MAPGIS software are submitted, the vectorized data files, corresponding system libraries and Chinese character libraries of MAPGIS software are often forgotten. Or the submitted sub-gallery is not the matching sub-gallery of the drawing electronic file, which leads to that when the drawing electronic file is opened, no information can be found, and the drawing name is missing, so it is impossible to browse.
Geological data quality of 1.2.
The text of geological data of some projects is vague, the boundaries of digital lines in the attached drawings are unclear, and the paper quality is poor; Some projects submit results reports by copying to save costs. These low-quality geological data are not conducive to long-term preservation and long-term archiving and utilization in the future. Some CD-ROMs of geological electronic documents are inferior or outdated carrier CDs. The data stored in this inferior CD-ROMs are difficult to preserve for a long time, and will soon disappear, with disastrous consequences.
1.3 Classification of geological data at intersections.
According to the format requirements, electronic geological data files are divided into the following eight categories according to their contents and forms: text, reply, drawings, schedules, attachments, databases and software, multimedia and others.
Because the provincial geological archives and regional geological archives have different understandings of definition and classification, some materials in annexes and other categories need to be classified differently. For example, the catalogue of geological archives and the catalogue of physical geological data are required to be classified as "Annex" by the provincial geological archives, and "Other" by the regional geological archives. Therefore, two types of remitted geological data need to be produced when the remitted units make remitted geological data due to different categories, and submitted to provincial geological archives and regional geological archives respectively. Although it does not affect the utilization of data, it causes certain difficulties in warehousing and archiving. I don't know which set of files should be filed in the end? If both formats are filed, then their categories are different.
1.4 compilation of geological data format requirements of intersection point.
There was a problem compiling 1.4. 1 text.
The text parts of geological data, schedules and attachments of some project achievements are not made according to the requirements of submission format, the title definition and classification are incorrect and inconsistent, or the definition chapters are omitted, or the redundant contents are defined; When inserting A3 format or landscape format, the page numbers cannot be connected because there is no adjustment; The report catalogue reported by some projects is inconsistent with the contents reported, and the map name or scale is inconsistent with the report catalogue. In some text reports, when the inserted table lacks the table name, or the inserted table is not on one page, the continued table has no table name and header, and the table file is not made by the table command in the software, so the label is unclear. The illustrations and inserted forms of some articles are not displayed upward on the computer screen, which is inconvenient for readers to browse on the computer and does not meet the requirements of remittance format. In some reports, the insertion positions of inserted tables, illustrations, photos and plates cover other text information. In the written reports of geological data of some projects, some fonts are not uniform, some characters are smaller than No.5, and the row spacing is inconsistent.
The problem of 1.4.2 in the attached figure
There are some problems in the drawings of some engineering geological data, such as the color of geological body does not meet the technical specifications, the color labeling is wrong, and the legend is missing. There are many problems when some intersecting graphs are converted into graphic files, mainly the problems of color loss, color shift and information loss when vectorized graphic files are converted into raster graphic files. Such problems should have been examined by the expert group, but they have not been reasonably solved, but have been postponed to the data acceptance stage, which will have a far-reaching impact on the quality of collected data and the development, utilization and service of data in the future.
The electronic document submitted by 1.5 is inconsistent with the paper geological data.
Sometimes when checking the geological data submitted by the project, it will be found that the contents of electronic documents and paper reports can not correspond to each other one by one. The reason may be that the report is constantly revised, and the final submitted electronic documents and paper media materials are not the same version. It is impossible to judge which of the two is the final version. It is also possible that when there are many large drawings in the report, the cost of copying one or more sets of drawings will be higher, so the manuscript will be handed in, resulting in inconsistency between electronic documents and paper media materials. Either the electronic file is not the final electronic file, or the electronic file has been modified, but the paper media data has not been modified. Therefore, when data managers receive the geological data of the project, the archived geological data is not the final version, and the paper media is inconsistent with the electronic files, which affects the future development and utilization of geological data.
There is a big color difference between electronic files with drawings and data in paper media, which may be caused by the following reasons: first, the sub-database provided by maps compiled with MAPGIS software is different from that used by printed paper media data; The second is the color difference of the plotter itself (the difference between four colors and six colors) or the color distortion caused by the poor quality of drawing ink. In addition, sometimes it may be caused by a virus or a defect in the software itself. When MAPGIS mapping software is converted into JPEG files, there will be some phenomena such as compression, color distortion, information loss and even pattern inversion. These are the reasons for the color difference between electronic documents with pictures and data in paper media. When receiving geological data, data managers should carefully check the attached drawings, find out the reasons, and communicate with project personnel in time to solve such problems.
1.6 the security of the electronic file of geological data submitted.
In some projects, the electronic documents of geological data submitted by the Department have some virus files because they have not been treated with anti-virus before submitting and engraving the CD, which will have a serious impact on the archiving and utilization of electronic documents and have certain security risks. There are also electronic documents of geological achievements submitted by some projects. Because the carrier CD is inferior, it is difficult to keep the data for a long time, and the electronic files stored on this carrier CD will soon disappear, which has potential safety hazards for the long-term preservation and utilization of the results. In addition, some electronic documents can not be read on general reading equipment, and can not be opened, browsed and used normally in the corresponding software environment. There are some problems that cannot be ignored in the future use of these electronic documents.
It is very important that the submitted electronic documents of geological data cannot carry viruses, and it must be strictly done. Because any electronic document with virus will cause potential danger to storage and utilization, and some even cause irreparable loss. The carrier of electronic documents of geological data submitted must be high-quality CD-ROM, so as to ensure medium-speed compatible mode, one-time recording, virus-free, and multi-segment recording is prohibited.
2. Do a good job in the collection and submission of geological data.
2. 1 Intensify publicity and enhance legal communication awareness.
Data management personnel should strengthen the Regulations on the Management of Geological Data (Order No.349 of the State Council), the Measures for the Implementation of the Regulations on the Management of Geological Data (Order No.1 16 of the Ministry of Land and Resources), the requirements for the format of electronic files of geological data (Order No.210 of the Ministry of Land and Resources), the filing requirements for original geological data and the filing requirements for physical geological data. Publicize laws, regulations and other documents and requirements, and distribute these legal basis, laws, regulations and other documents and requirements to all projects, and often communicate with project leaders to organize project personnel to learn, so that project personnel can enhance their awareness of legal submission, deeply understand and master the new system, new technology and new requirements of geological data management, and lay a good foundation for the submission of project geological data.
When the project personnel finish the field work and sort out the data, the data manager should release the format requirements and briefly explain the main writing requirements when compiling the report. Let them pay attention to the correct use of chapter titles, uniform font size, font size not less than No.5, line spacing and other issues when making reports, prepare reports according to the exchange format, and make attached drawings, so as to lay a good foundation for the geological data exchange of the final results of the project.
2.2 Strengthen the training of data management and data acquisition personnel to improve the quality of personnel.
Strengthen the professional training of electronic document production for project submitters and grassroots data managers. In view of the problems existing in the annual submission work, the geological archive will organize regular study, so that they can understand and learn the relevant management documents and regulations, and understand the scope and specific requirements of the geological data submitted. Only by learning new theories, norms and technologies, exchanging work experience with each other and improving the quality of data managers and data collectors can the level of data collection be continuously improved.
2.3 Strictly control the quality of electronic documents of geological data.
The submission of geological data is the key to data management, and the acceptance of electronic documents of geological data is the focus of data submission and acceptance. The quality of electronic documents directly affects the modernization process of geological data management, so data managers should take the quality of electronic documents as their primary task.
3 Conclusion
Geological data is an important embodiment of the labor achievements of geologists, an important basic information resource obtained by geological exploration technology for social and geological prospecting work, and an indispensable important data base for further geological work. Data managers shoulder the arduous task of collecting, sorting, keeping, developing and utilizing geological data. Responsible for history, the country, and the receipt of data, and check and accept geological data in strict accordance with the requirements of national specifications and submission formats.
