Design And Implementation Of Visualization And Analysis Platform Of Liaoning Province Construction Land Spatial Data

The industry of land resources is the lifeblood of the national economy,so its information construction is the most important in the present development.After many years of development,the business system of land and resources industry has been great progress.But as the development of the Times,the business demand for supervise and verification of spatial data is growing,which causes some deficiencies in the verification after approval of the land for construction.There are not special visualization and analysis platform correspond to the spatial data,which leads to the lack of regulatory efficiency and the need of intervention of staff.Therefore,this thesis designs and implements visualization and analysis platform for spatial data of construction land in Liaoning Province.It has great significance to the management of land resource industry which develops scientifically and reasonably and informational directionally.The system is developed based on the verification platform of spatial data for construction land in Liaoning Province,which emphases on the spatial data which verifies after approval and provided.The main function of this system is the analysis and visualization of the spatial data,the visualization function is mainly visual display the verification land of the project superimposed with basic farmland map,land utilization plan map,land utilization state map and land remote sensing map.And the analysis function includes overlap analysis of project land block itself,coverage analysis of basic farmland,utilization analysis of land plan,statistical analysis based on land category,the relationship analysis of land approval and provide,and the system also has some function to deal with spatial data.The thesis firstly introduces the background,significance and related technology,secondly analyses the requirements of this project,designs the overall framework,divides modules based on the requirement analysis and designs the main database table structure and E-R relationship,thirdly implements the function of the modules and tests the main function of the system in order to evaluate the performance and availability.Finally,the thesis summarizes and illustrates the future work.
