GIS Based Forest Resources Management Information System

Process-oriented programming methods to manipulate the data and data separately, resulting in a collection of complex software development and maintenance difficulties, because this method to simulate reality system software, software functions to solve a system due to changes in the environment, function It will change, leading to difficulties in software maintenance, and software development costs far less than the cost of the software. Object-oriented programming gradually replace the software simulation program design methods, process-oriented reality system, is solved as collections of objects, such software development and maintenance easier, because the function of a system will continue to change, but the system part does not change, the corresponding software maintenance easier.Object-Oriented spatial database, spatial data integrated in the objects, help people to understand, but also conducive to the management and maintenance of the database, but also conducive to the development of spatial database application, Geodatabase spatial database model is a spatial object-oriented data model. This object-oriented model is same to object-oriented programming.In order to satisfied Chinese Academy of Tropical Forestry Experimental Center Forest Resource Management of digital and information technology, scientific research and experimental requirements. Study In this thesis include:(1) according to the national forest resources information system standards, how to use Geodatabase modeled digital raster topographic layer, contour lines layer, Elevation Note record a point layer, DEM, Tin, the main center of Tropical Forestry and precious species of tropical plants (eucalyptus, pine, wood frame, red vertebrae, southwest Cheng, Mytilaria etc.) pictures with no background object, and existing survey data: vector graphics data (contours, spot heights, state, rivers, roads, laboratory, experimental field, compartments, business class small classes, annotation and other vector layer),, (2) How to build Geodatabase database of forest resources, through Mircrosoft SQL Server 2008 implement its really stored. (3) the use of Visual C ++ 2010 and ArcEngine 10.1, perform GIS secondary development of two-dimensional map display data browsing, query statistics, analysis, three-dimensional map display navigation, feature selection, two-dimensional and three-dimensional map of functional integration in the same software.Eventually Geodatabase database organization, storage, management and maintenance of forest resource database, a high secondary development of GIS integrated forest resource management information system software, operating efficiency, facilitate two-dimensional data and information management and application of three-dimensional data, based on the basic realization GIS of forest Resources Management information System, and the further development and maintenance of the system is more convenient, you can further adapt to the changing needs of Gerim center information systems.
