Study Information System Of Kailuan Coal Mine Land Use Base On The KML Format

With the development on 3S (GIS,RS,GPS) technology in the application, Using traditional management systems approach has clearly failed to keep pace with social and economic development needs for the distribution of land mines scattered, complex attributes, management of complex features. So, By using GIS technology to integrate the spatial data and attribute data of the mining land use information and on the basis of using space database management system, using GIS secondary development capabilities to developed mining area land use information systems to make land-use a variety of information visual graphics, tables and charts way out. //And using the spatial analysis functions of GIS and taping the information hidden behind in the data has played an important supporting role for scientific analysis of land mine use of informationThis paper introduces GIS spatial analysis methods , Digital Earth platform and Google Earth is a representative , Spatial data exchange standards KML ,the network access model of new geo-information, and the key technology of development of geographic information system, include:Component GIS technology, ArcGIS architecture and secondary development approach, Visual Studion.NET development platform, and spatial database technology. It is the Design ideas than using visualization development platform. NET to development the information systems of mining area land use based on these components spatial data processing, spatial analysis than ArcGIS Engine provide. The system's main function include map browsing, vector layer enquiries and statistics, , as well as the output of thematic maps and the buffer zone analysis, overlay analysis, factor analysis, GIS spatial analysis functions. The spatial analysis, statistics operator functions were programmed with VB.NET by calling ArcGIS Engine components in the relevant methods in the interface. The system also integrates Global Mapper and Google Earth software, convert file of sptial data into file of KML format by using Global Mapper,display the data by Google Earth.Development of the system, made full use of object-oriented development language and the development of component-based GIS technology to build, effectively improving the application of geographical information systems development efficiency, and has a good user interface and better functionality.In this paper, explore a new way for the systems study of KAILUAN mining area land use of information and provide strong technical support for mining land use scientific information management and decision-making.
