Introduction to 0

Industrialization of geological data information service cluster is a systematic project. To carry out this work, it is necessary to comprehensively consider all aspects of the whole geological data. This paper mainly introduces some thoughts on developing and promoting the clustering industrialization of geological information services in Zhejiang Province under the overall requirements and work objectives of the Ministry, combined with the actual situation and work characteristics of Zhejiang Province, in order to attract more attention and discuss with colleagues.

1 Present situation of geological data information service in Zhejiang Province

1. 1 Basic information of geological data

By strictly implementing the geological data collection system and receiving and checking the collected geological data according to the specified requirements, in recent years, the quantity of collected geological data in Zhejiang Province has been kept at a high level, and the quality of collected geological data has been continuously improved. By the end of 20111,the total number of geological data in the collection reached 8364, an increase of 5. 1% over the previous year.

At present, the digitalization of graphics and text in the whole province is progressing steadily, and it is drawing to a close. The utilization rate of graphics and text geological data is high, reaching 83% ~ 85%. 20 1 1 year provided 2083 person-times, 453 1 time and 47305 times, among which digital data 1800 person-times, 3787 times and 40463 times were used respectively.

1.2 Progress and present situation of promoting industrialization and modernization

According to the requirements and objectives of the Work Plan for Promoting the Cluster Industrialization of Geological Information Services issued by the Ministry of Land and Resources, Zhejiang actively promotes the industrialization and modernization. First of all, combined with the actual situation and working characteristics of Zhejiang Province, the implementation plan of clustering industrialization of geological data information service is formulated. Second, pay attention to the digitalization of geological data, and the digitalization of geological data in the collection is constantly improving. At present, 4,896 kinds of geological data have been digitized, and the digitization rate of geological data in the collection has reached 95.8%.

2 Zhejiang geological information service "two" ideas

2. 1 Complete the digitization of all geological data collected in this province.

By the end of 20 12, the geological data collected by the whole province will be digitized. By then, all the geological data collected in the whole province will have corresponding electronic files, so that all the geological data collected can be used as the basic data of the "two modernizations" smoothly, providing the most powerful basic data guarantee for the development and promotion of the "two modernizations" and making sufficient preconditions for the development of the "two modernizations".

2.2 Vectorization and decryption of important classified graphic digital geological data.

Taking the task of "clustering and industrialization" put forward by the Ministry as an opportunity, based on the digitalization of pictures and texts, and using information technology as a means, some important and highly utilized classified geological data are decrypted by vectorization technology to form geological data products for public use, so as to improve the management level of geological data and the social service ability of geological data information, and give full play to the role of geological data in serving the whole social and economic development.

Vectorization of geological data is a systematic project, which should be promoted according to unified standards, procedures and norms as far as possible, mainly including the following four aspects:

(1) Construction of geological data database.

The state builds according to three categories: metadata catalog database, graphic geological data database and thematic database (various databases classified by specialty). Let's first consider the construction of graphic library and graphic geological database. The service management part meets the requirements of "one map" and its core database construction and is included in "one map" management.

(2)*** Enjoy the service.

According to application and customization, it is divided into three levels: service directory service, open data service and product service. Data catalog and public data depend on the external service system in the form of Internet. Non-public geological data rely on geological data center to carry out services.

(3) Data running environment.

Fully considering the existing data and system platform foundation, the spatial data management software selects mainstream products at home and abroad and supports universal exchange formats; Database software can choose large mainstream relational database products at home and abroad (our library has a dedicated server).

(4) Network construction.

The external geological data sharing service platform relies on the Internet to provide services to the outside world, and the internal client uses IE browser as the operating platform, simulating the online form, which is convenient, fast, simple and easy to use.

2.3 Construction of geological data management service system

Through the construction of geological data management service system, data reception, acceptance, sorting, identification, storage, utilization and whole process management are gradually realized from four aspects: business management, data management, data utilization and social service, so as to improve the network service level of geological data, improve the retrieval ability and service ability, and improve the management and service efficiency of geological data.

The main functions of geological data management service system include: data receiving, acceptance, classification, charging and other content management; Establish a data pre-trial mechanism, gradually review and submit the submitted data correctly, and establish content association; Establish a strict authority work system, support the rapid retrieval of the attributes and contents of all data files, and require orderly operation in combination with work authority, which can facilitate the handling of data borrowing and dynamically monitor all work processes; Request the system to provide data copying, printing, ordering and special services; Provide online information access for intranet users according to work authority; According to the requirements of geological data to provide services to the society, establish an audit mechanism; After publication, it will interface with the existing information portal to provide query, browsing and other service functions.

Geological data management service system mainly adopts the following technical methods:

(1) Use advanced and mature information technology to build a provincial geological data file network management and application system to ensure the advanced, stable, safe and extensible nature of the system. For example, the application of portal technology provides timely and personalized design suitable for humanized management; Development of application browser/server (B/S) mode structure; Apply "free and flexible workflow" technology to adapt to the concurrent or collaborative processing flow of multiple departments and personnel; Using coding management technology to realize effective document access: using advanced retrieval and full-text retrieval technology to query geological data and information needed by users.

(2) The system supports the coexistence of various formats and types of files and orderly, purposeful and efficient management.

(3) The system provides a strict authorization management mechanism, including four ways: default authorization, standard authorization, temporary authorization and classified authorization. Users can use and serve geological data according to their own needs and work authority.

(4) The system provides a complete security system, including user authentication, data access control, process operation monitoring and system log audit functions to ensure data security.

(5) The system strictly follows the Code for Scanning Digitization of Graphic Geological Data (SZ 19900 1 2000), Detailed Description Rules for Geological Data Files (DA/T23-2000) and Management Code for Photographic Files (GB/T1/KLOC-).

(6) The design of the universal interface for data interaction of the system adopts related standards such as object-oriented database and structured query (SQL, XML, etc.). ) to meet the requirements of users.

(7) The system supports large-scale user applications and multi-user requirements (>; 200 information points), and the storage conditions of large-capacity geological data provide services normally.

(8) System adoption. NET development environment, which is suitable for the application requirements of large and medium-sized network environment, has the advantages of good stability, high operation efficiency, simplicity, no redundancy and good maintainability.

(9) The database adopts SQL SERVER2000 high-performance relational database management system, which realizes efficient data access and supports the attributes of users' geological data and the high reliability and stability of file storage.

2.4 Provide clustered geological data information services for the "One Map" work.

According to the requirements of the "Golden Soil Project" construction plan of the Ministry of Land and Resources, the national "One Map" project plan and the resource informatization construction plan of Zhejiang Province, in the "One Map" construction, the information service of geological data is related to the mining administration, and the geological data information of the geological data catalog database, digital results of pictures and texts and other collection results is related to the construction of provincial mineral resources master planning database, exploration right distribution database and mining right distribution database. Two-dimensional and three-dimensional graphic display platforms are developed, and the interface between geographic information system and online examination and approval system of exploration and mining rights is developed, and relevant geological data information runs through it, which realizes the geological data information support and service in mining rights related fields, provides geological data background information service for mining rights decision-making and approval, and realizes the clustering of geological data.

2.5 Develop geological data service data products.

On the basis of clustering work such as digitalization and vectorization of geological data, the development experiment of geological data public service data products was carried out. In order to meet the demand of data sharing and social service of urban geological information on local area network and wide area network, a system of urban geological information sharing and social service based on B/S mode is established. The system has the functions of geological data catalog retrieval, achievement data retrieval, three-dimensional model display and analysis, file upload and download, dynamic news management, professional chart generation, metadata release and so on.

Establish an urban geological data management platform for multi-thematic applications, an analysis and research platform for geological professionals, a decision support platform for government personnel, and an information sharing and service platform for the public. Realize the real-time application of data, including the development and testing of data products such as query statistics, professional map compilation, professional analysis and evaluation, three-dimensional geological modeling, report production and output.

Through the work of cluster industrialization, the network system of geological data information service and product service is finally established.

3 "two-oriented" work should be considered to establish safeguards.

In order to further improve the clustering industrialization of geological data information service, corresponding safeguard measures are needed.
