Introduction to 0

Geological data information is the concentrated expression of the important achievements accumulated by geological work for a long time, the main carrier of geological work serving the society, and the important basic information resources supporting national economic construction and social development. With the economic development and social progress, the demand for geological information in all walks of life is increasingly strong. However, due to the decentralized management of geological information, the mechanism and means of sharing and comprehensive utilization of geological information and the ability of online business services are still relatively weak, and the public participation is not high. The geological information "ecological service community" that encourages information consumption has not yet formed, which restricts the effective play of the potential value of geological information.

1 industrialization of geological data information cluster

In China, with the landing of cloud computing, the perception of the Internet of Things and the mining of big data, many industries and fields have also started "cluster" projects. 20 10 The Ministry of Land and Resources issued the Work Plan for Promoting the Cluster Industrialization of Geological Information Services, which is demand-oriented, aims at improving the efficiency and benefit of geological information utilization, and takes the innovation of geological information sharing service system and mechanism as the driving force to build an information sharing service system that widely exchanges and serves the society, forming a new situation of rational distribution of information resources, classification of information services and full participation of geological exploration units. It has promoted the formation of a benign operation mechanism of regional service integrating data collection, exchange, integration and update, accelerated the geological information service and improved the geological information service capacity [1]. This is the first time in China's geological industry, and it is a major change in the traditional concept and mode of geological data information service, which is conducive to prolonging the industrial chain of geological work, improving the service capacity of geological achievements, solving outstanding problems in geological data management and avoiding repeated investment in geological work [2].

Under the overall arrangement of the Development Research Center of China Geological Survey, Xi 'an Geological Survey Center undertook the demonstration research project of geological data information cluster in northwest China. Based on the six principles of "adhering to public service, comprehensive coverage, interconnection, safeguarding rights and interests, gradual promotion and participation of all parties", the research group focused on the construction of geological data database, service platform, data operation environment and network around the guiding principles of integrating clusters, deep development, realizing informatization, socialized service and developing industrialization. With modern information technology as a means, we will build a regional geological information resource sharing service platform, establish a geological information sharing mechanism, gradually eliminate or connect isolated islands of geological information, bring our scattered and isolated geological information together on a unified sharing platform, and integrate and apply them, and gradually form a distributed and multi-level geological information service capability that can meet the different needs of the northwest region.

2. 1 northwest geological data information cluster service mechanism

The research group cooperated with Xinjiang, Shaanxi and Ningxia Land and Resources Information Centers, actively and effectively explored and tried to build a normal mechanism for regional and provincial geological data sharing and service through investigation, visit, observation, training, guidance and cooperation, and reached a consensus on geological data management mechanism, exchange system and service model. Geological data information "cluster" should be escorted by geological data collection, management and service system on the premise that all management functions are fully in place, follow unified standards and norms, take "node group" as aggregation unit, and carry out cross-regional collaborative services for different user groups through the network * * * sharing platform. At the same time, with the project as the link, the business communication between regional and provincial levels has been strengthened, and the normalized linkage service mechanism has been established through cluster networking, gradually realizing the transformation of geological data from traditional information collection to modern cluster service.

The elements of regional and provincial geological data information collaborative sharing and service mechanism are summarized as follows:

1) system guarantee. From the aspects of expediting, receiving, acceptance, storage and submission of geological data, the geological data management system is effectively implemented, the internal operation process is improved, the quality of submission is guaranteed, and accurate and authoritative data sources are provided for information sharing.

2) Build platforms and passages. Relying on information and network technology, we will build a hierarchical, point-to-point, real-time, efficient and intelligent service channel, eliminate information islands while safeguarding local rights and interests, and expand the field and scope of geological data information service.

3)*** Enjoy the service: On the basis of earnestly implementing the geological data collection system, through the construction of cluster node system and other technical means, we will establish efficient services and point-to-point channels between regions and provinces, realize the release and linkage services of geological data information, and present a seamless service window to the outside world (Figure 1).

2.2 Northwest Geological Data Information Cluster Service Platform

Guided by the actual demand, following the frontier theory of information technology, closely following the theme of "clustering" of geological data information, and aiming at the present situation of centralized and decentralized collection of geological data information, the research group developed a geospatial information retrieval system. The "tree or mesh" networking form of "department, bureau, region, province and city" presents a node cluster service mode, which provides an operational support environment for building a geological data information node group with extensive participation, wide coverage and interconnection.

Geospatial information retrieval system takes "data center" as the aggregation core, and constructs a resource-oriented and service-oriented parallel architecture system. Through various technical means such as node certificate authentication, data discovery, information transmission, data aggregation, discrete storage, loose equivalence, parallel retrieval, information reconstruction, etc. , which realizes the functions of information collection, cross-domain deployment, customized access and diversified retrieval means between geological information cluster nodes and architecture groups, and provides the background and background of the cluster environment.

On this system, we can realize: geological data information cluster publishing service; Geological data information retrieval service based on spatial constraints, attribute keywords and category characteristics: multi-scale integration "one map" interactive operation environment of geological data spatial elements.

At the same time, in view of the present situation of distributed collection of geological data, a node group with wide participation, wide coverage and interconnection can be constructed through network channels, which can present a joint networking form and service mode of distributed operation and maintenance, collaborative aggregation and cluster sharing of geological data information; It has a retrieval service mechanism based on spatial information to provide geological data to the public; It can provide an interactive drawing environment for professionals and an embedded interface for cross-industry applications.
