The Construction Of Geological Exploration Information System Based On C/S And B/S Mode And The Data Organization Of Geological Survey Project

Abstract:Along with the global business expansion of Non-ferrous metals Resource Geological Survey, how to real-time control and share the geological exploration information distributed around the world and how to make efficient cohesion between field staff and professional processing indoor become the emphasis and difficulty in the construction of geological exploration information. The building of non-ferrous geological exploration information system effectively solves the difficulty of the geological exploration data which cannot achieve resource sharing, real-time tracking and management of the field project data.Non-ferrous geological exploration information system is an integration information system which has a set of functions including geological exploration data acquisition, management, analysis, data exchange, the auxiliary preparation of geological report and so on. Geological exploration information system architecture is based on C/S and B/S mixed mode, using a service-oriented design ideas. The B/S system mainly provides the querying, browse and statistical of Geological exploration data. The users can view the geological exploration data via the web browser after logging on this system based on their privileges and the managers can edit part of assessment information. According to the needs of geological exploration business, geological exploration information, the field exploration project catalog system, the geological report prepared auxiliary systems as well as the off-line version of the geological survey project management system have developed based on C/S mode which provide the functions of geological survey projects information collection, editing and data entry.Based on the analysis of the overall design framework of the geological exploration information system, the paper focuses on the organization and management of geological survey project data. The subject of research includes the following aspects: (1) Combined with practical applications, this article extracts business model of geological exploration project management of Non-ferrous metals Resource Geological Survey through studying deeply the scope of business and workflow, and then provide the overall framework of geological exploration information system which is based on business process of geological exploration project and has the frame design mechanism (C/S offline system+B/S online system).(2) Based on data warehouse technology, the geological exploration information system has realized the integration management of the spatial information, document information, metadata information and other geological exploration project information. Based on spatial data engine technology, the system realizes the unified storage and management of spatial data and non-spatial data in a relational database. On the basis of MapGIS K9, this paper creates an integrated development environment based on the C/S and B/S application system. It also has realized the map publishing, browse, locating and editing of geological exploration project data such as documents, graphs and vector data based on Web Service technology.(3) The geological exploration business includes the management of geological exploration project and mining rights. This article focuses on the research of the management about geological exploration project data. Geological exploration project data can be divided into basic spatial data, attribute data and geological exploration business data. The system realizes the integrated storage and management of the five stages of the geological survey project data which includes demonstration, design review, organization and implementation, reporting, data collection. Part of mining right management data such as mining right certificate, exploration right certificate and other related documents, will be classified as a geological exploration project management data category.(4) The geological exploration information system realizes the creation of the geological exploration projects, the collection of geological exploration project field data, the organization of geological exploration project report (including demonstration, designing and reporting), the storage of geological survey data and project management data as well as realizing of the online query, statistics, editing, and other functions of the geological survey project data. And it develops the related interface to ensure the data flowing in each subsystem.(5) On the basis of work as above, as an example of Changhanbuluo area, based on geological exploration information system the paper realizes the creation of geological exploration projects, data collection, data exchange and data management and the information application integration and sharing service of business data and spatial information. The practical instance proves non-ferrous geological exploration information system efficiency in managing geological exploration project data, and plays a promoting role in the development of informanization construction for Non-ferrous metals Resource Geological Survey.
