The Design And Realization Of "One Map" Management System Of Land Survey And Planning In The Zhengdong New District

Zhengdong New District Land Survey and Planning "a map" management platform is a variety of survey planning data induction and finishing,in a certain period of time the city's economic and social development,land use,spatial layout and the comprehensive layout of the construction land,Specific arrangements and the implementation of management is the city development decision-making,joint departments to coordinate and plan to support the technical support platform to implement a powerful tool.However,the relevant data scattered in the land,mapping,planning and urban construction and other relevant departments,planning data co-ordination,circulation and sharing difficulties.At present,the land survey and planning department of Zhengdong New District has accumulated massive data and documentation,which show the characteristics of multi-source(paper document,Shp format data file,AutoCAD document,PDF document,image data and Raster image format file),in the wisdom of urban information construction continues to strengthen the process,how to various types of drawings and documentation for efficient and safe management and data integration and sharing of vector data and online map synchronization matching and Map online editing operation is the urgent problem to be solved.In view of the above problems in the management of the land survey data of Zhengdong New Area,this paper takes Zhengdong New Area as an example to construct the Zhengdong New District survey and planning management system platform to realize the safe and efficient management of multi-source heterogeneous data,The method of finding the corresponding position of the same name node in two kinds of heterogeneous data is established,and a fast conversion model method is proposed to construct a node vector with the same name node.The vector data of the different coordinate system and the online The map is synchronized.This paper focuses on the superposition of "one map" map of the land survey and planning of Zhengdong New District,and the online editing,related algorithms and key technologies of the map.It aims to establish a "map" management platform service system for the land survey and planning of Zhengdong New District.Based on the analysis of multi-source heterogeneous data,combined with WebGIS technology,on-line overlay of maps and data conversion theory of different coordinate systems,this paper starts from the application software development life cycle and the user's needs,according to the system needs analysis Design,system implementation and system testing of the structure of the organization and departure,research and development of Zhengdong New District survey planning management system platform.The system calls the map service through the ArcGIS Server REST interface and stores and manages the data through the ArcSDE space database and the SQL Server 2008 database.Web side uses Ajax and JSON to interact with data in the background.The system enables efficient storage of multi-source heterogeneous data,online editing of maps,overlay display of map and output printing.
