Design And Implement3D Cadastre Database System Based On Arcgis Platform

In the background of the second national land survey, in order to fully ascertainthe status of land use and master’s land base data, survey results and theimplementation of information technology, network management, establish andimprove land surveys, statistics system and registration system, to achieve socialservice land resource information, to meet the economic and social developmentrequires land macro-control and management of land and resources, the constructionof three-dimensional cadastral database system will be able to better serve the landand resource management and economic development. For standardized cadastralmanagement, scientific development of land resources and ensure sustainable land use,has an important role in guiding and extensive application value.In this paper, Changchun3D cadastre database building a database project as thebackground to the database established as the starting point, the basis of summarizing3D cadastre database establishment and application of the described city three intoday’s surveying and mapping has been applied has become more broad-based, again,Changchun3D cadastre database project can learn more and play a good role in thepromotion of projects related to three other provinces.The main achieve the following results:1) Cadastral data acquisition and processingThe use of aerial photography, laser LiDAR point cloud technology, tiltphotography and other means of production models, summarizes the technicalmethods of urban three-dimensional modeling, two-dimensional cadastral database ofparcel data model used to establish the body parcels, parcels plane body model rangeand scope of the two-dimensional coordinates of the same parcel, its height accordingto the height of buildings within a two-dimensional parcel was classified so as toconstitute a closed polyhedron. Provide technical reference for the futurethree-dimensional Geographic Information System cities.2) Establish3D cadastre database3D cadastre database is based on Arcgis platform secondary development, theconstruction of Changchun3D cadastre database system, the system through userpermissions, job classification group management, user identification and accesscontrol of CRUD, according to their professional maintain their data, according tosystem functions to customize the user interface, according to user level login and access to different data resources3）To achieve functional3D cadastre databaseThree-dimensional cadastral database system provides a two-dimensional imagemap services cadastral management system. Dimensional cadastral managementsystem3D cadastre database system provides advanced analysis capabilities,including cost analysis, statistical analysis, covering analysis, dynamic regulation. Itplayed a reference to the relevant projects in other provinces.
