Research On The Land Use Map-spot Change Ascend Analysis Based On Match Relationships

Land resources as an important resource form, is the carrier of all social activities, but also the production of material life of human beings, therefore, the land questions have always been a great concern in land management work, such as land disputes ?land evolution of practical problems, and it is often inefficient if these problems are simply rely on artificial completed. In recent years, with the management form conversion of land resources from traditional paper maps and cadastral information to the direction of digitized, it is of great practical significance on how to use the land management system to analyze these issues.In the real world, whether it is a land disputes or evolution, the essence is analysis on different time states, polygons how changes in land use issues, the evolution of the logical model is on tracking and polygons retrospective analysis. In this regard, this paper takes entities matching as drive to seek internal relations from different periods map spots, complete the function of track back inquiry. For this goal, the specific contents of this article are as follows:(1) Take consistency processing for different periods map spots, so that improve the speed and accuracy of entities matching.(2) Explore the match process and matching methods, classify the existing means of entities matching, analysis the methods of rough matching and matching strategies under different modes, build fast and accurate matching program suitable for map spots based on location?area and form.(3) The track back analysis' research on the types and methods, analysis the changes information corresponding to the matching result, establish the connection of the matching result, and query the different types through the SQL algorithm.(4) Take.Net platform and Arc Objects to complete the prototype system, Validate the above theories and methods.
