| Generally speaking, the computer application contains writing, data and image in current various domains. But the most jobs require all of the three. And the appearance of Geographical Information System (GIS) has solved the problem.Geographic Information System and Global Positioning System is a kind of integrated information system on the basis of geospatial data, with the support of computer hardware, software and GPS devices. It can accomplish operations of management, operations, analysis, simulation and display on the spatial-related dataThis research project is based on "oil land management application integrated geographic information system" which use GeoMedia InterGraph Professioanl 5.2 software as graphic/file management platform. The research based on the characteristics of land management issues under the oilfield business, effectively conducted a needs analysis, and an outline design, data analysis, database design and detailed design; Through GeoMedia Professional application software, Component Development Technology and metadata management technology are used, the full use of GIS functions into a network security and information technology, Microsoft VB6.0 language completed by the system C / S desktop application development, the basis of geography and the oilfield in the data storage, query and retrieval, statistical, spatial analysis and application of topological analysis functions;on the basis of GeoMedia WebMap5, network applications based on the use of dynamic graphics released in ASP development environment of the system completed the B/S network application development, the system will run on existing oilfield enterprise network environment, the land management business enterprises Oilfield officers on the network can be achieved in the browser by query and statistical analysis, and other basic operations; advanced geographic information system (GIS), global positioning system (GPS) and personal digital assistants (PDA) with technology, were built to facilitate the enforcement of land oilfield site map the oilfield land portable GPS applications.This subject used GIS/GPS/DBMS integration of technology, not only to achieve the electronic management of land records during the oil-field land daily work, but also achieve in the integrated management to incorporate text and graphic, and further realization of portable, mobile work map, the results of research topics can be used in various firms the location-based graphics information and asset information site inquiries, update, and other integrated applications, which can effectively improve their efficiency.This system use InterGraph GeoMedia as a basis of geography and the Graphic management platform, GeoMedia is easy to learned, secondary development capability is strong, and can connect with the common database, the realization function is powerful. GeoMedia keep up with the IT development mainstream, but in the direction of the development of GIS technology with new innovations, in the multi-source data integration, data connectivity technology and space components of the technical aspects stand in the forefront of GIS.This integrated application system building was preliminary achieved the desired results and demands. Oilfield land management information systems have become integrated oil field operations personnel land management departments indispensable to the daily work of one of IT application systems, particularly land application of the monitoring system developed to expand the establishment in the entire oilfield enterprises star a new time, the GPS mobile industry with the work of the ground, are in a leading position. The success of the system built, the land management in the oil field work related businesses have played a pivotal role in daily work is a good assistant.This integrated application system building, both in application mode, functional and practical aspects, such as data informative achieve the set targets, the oil fields in the management of land ownership status of the microcomputer, network inquiries, as well as diversified applications of electronic data, such as construction and stand a new level.At the same time to achieving this integrated application system, the paper will simple to introduce relevant knowledge of the relevant geographic information systems, GeoMedia Professional, and GeoMedia WebMap. |
