Design And Development Of Land Use Normalization Survey System

The survey of land use status change is the main way for the state to master the situation of land use change and obtain the data of land use status.It is a field survey on the changes of land use map spot,ownership boundary,administrative division and so on.The internal industry completes the update of the land use status change data and updates the land in real time.The complete process of using the database and reporting.Under the support of 3S technology,network transmission technology and spatial database technology,the management and technical problems of five aspects,such as "application sharing,rapid investigation,timely discovery,truthfully reporting,continuous updating",have been put forward,and the transformation of the annual centralized change survey to dynamic change normalization investigation is put forward,from land management.Solve the change problem in time.The survey work takes the quarter as 'the main cycle,progressively carry out the land use normalization investigation,improve the accuracy and frequency of land survey data change,improve the current and precision of the land use normalization database,and fully realize the efficient supervision and application of land survey and land use data.On the basis of in-depth understanding of the user needs and specific operation processes and patterms in the process of land use survey,the paper uses WebGIS technology,network data transmission technology,image data organization technology,spatial data organization and other technical design and development of land use normalization survey system.In view of the image data in the system database,the organization and management model suitable for remote sensing image data in this system is designed,and the remote sensing image data is stored in the way of ArcSDE engine and SQL Server database,which is organized in the way of grid directory.In view of the large,multi batch and different administrative divisions of the map spot data stored in the system database,the pattern of map spot management and organization based on the mission batch,the administrative division and the regional image is designed and designed,and the method of the integration of the annual change survey In order to control the state of the spot and the status update of the spot,to realize the efficient management and application of the pattern spot,the pattern of pattern spot state flow is put forward in the light of the dynamic update and the process of business circulation in the condition of the land use normalization.Based on these data organization management coordination work,and combined with the specific operation process of land use normalization,a land use normalization system suitable for multi level,multi role,multi sector organization and multi resource management is designed and developed.The system has realized the function of the system backstage management,the investigation of business function and the work of data statistics report.Many functions can be achieved to achieve the goal of efficient management and application of land use data of the system and the normalization survey data is put forward.
