Application Research Of Parcel Unified Coding Information System

In recent years, with the acceleration of land and resources informationization and the rapid development of urban-rural integration cadastral management, unified formulation for nationwide parcel identifier has been promoted the process of the integration of cadastral management further, and unified formulation for parcel in cadastral management also plays an important role. There’s sharing work efficiency on the low side, sharing data in cross-platform many difficult problems,in the unified formulation for parcel application research, so the application research of unified formulation for parcel carry out a theoretical and practical significance.This thesis elaborate the theories and methods in parcel coding unified formulation; summarizes summarizes the operation procedure of the parcel coding unified formulation, including preparation, data preprocessing, division of cadastral district and cadastral sub district, coding reference and other processes. System design are analyzed on the basis of the data processing,the small map spot fusing and results data sharing problems, and puted forward the corresponding solutions.Developing the parcel unified coding experiment information system and realize the technical methods of various main function modules. Development of the information system can realize the data processing, parcel coding unified formulation, the output of the new and old code table, data output services such as main modules. The data processing function module can be used for automatic search and improve the missing attribute fields, and solve the low efficiency of manual inspection, poor accuracy such as problem; based on the analysis of the current coding system sharing work efficiency on the low side of the influence factors, the design has realized the service function in the unified coding system, both to meet the requirements of operation department of result data, and to realize data sharing between the two different platforms, more convenient to coding results applied to the cadastral management work.Unified coding experiment system of this thesis designed and implemented verified the feasibility by using area actual measurement data, the main functions module of the coding system is verified in turn, the results show that the system is feasible in practical application.Studying of parcel unified coding information system application in the daily cadastral parcel to change management, realizing the parcel unified coding is the key point of the history data management and demand, and can be more reasonable management parcel of history data, providing reliable legal basis for land ownership disputes.The numbering algorithm of the parcel unified coding is designed, under the premise of the daily cadastral management work without affect,and high efficiency of the original of the cadastral management system software upgrade fast of parcel unified coding part. And through analysis the application of the right to rural land contracted management of approval register and the real estate registration and certification of the unified and these highlight the cases of the importance of unified coding in cadastral management.
