Construction And Application Of Online Land Supervision System

With the rapid development of China's economy and the growing population,problems caused by land are increasingly grim.The local governments became illegal instead of the person.Land Supervison is imminent.Therefore,it's important to establish the national land supervision mechanism who's main target is to supervise the management and the land's use of the people's government of provinces and municipalities and strictly”18 million acres of” arable land red line.Currently,the most immediate problem of land supervision is that inspectorate people are few and every inspector has heavy task with large area.It's need to develop information technology equipment and means of land to reform land supervision's work pattern in today's rapid development of computer,which can improve the efficiency and quality of work of inspectors.The thesis is aimed at the cross area and complicated dispersion?low efficiency and other issues of current land supervision.It's study on “the online land supervision system” which focuses on building and publishing the entire system and database,it established a "the sky see,the earth management,online search" online land supervision system.The system is achieved and practice as an example in the Supervision bureau of Shanghai.The main research contents are as follows:(1)The article is unified the entire business processes of land supervision with the analysis of the land inspectors' work requirements.Based on the existing research results and data collection of the system,the overall architecture,operating environment,and functions modules of the online land supervision system are designed.(2)According to the different data of the land supervision,the article designs the land supervision database and organizes the image data and vector data as well as the related business table.Land supervision data management subsystem is developed to achieve a unified storage ? management ? inquiries and updates in real-time of land supervision data using the.NET platform.(3)It achieves the release of the vector data using ArcGIS Server and the image data using TopRSServer which is developed based on the Rest + WCF architecture.(4)It designs the two-dimensional map platform to achieve the retrieval and analysis of raster and vector data;the land supervision system's front frame is builded using Flex technology,and the call ? query and analysis of data is realized through ArcGIS API for Flex,the network's share of the land supervision system is achieved too.
