Study On Management And Application Of Soil Confiscation Information With Temporal Feature

Land resource is essential part of national economy and society, as a non-regenerative resourse,it plays more and more important roles in national economy construction and social lives. In recent years, with the development of the every operation of land management, especially with the completion of urban cadastral investigation, all kinds of data, map, text material is growing very fast making cadastral information expanding, and daily cadastral work became more complex, traditional cadastral information management work can not meet the needs, so it is very important to develop cadastral management software based on GIS.The Soil Confiscation is a most important part of the cadastral information management, so develop Soil Confiscation management software based on GIS is very important. The data is the base of information system that in the GIS includes spatial data and un-spatial data. The data of the Soil Confiscation Information System except has the common spatial data's attribute, it also has time attribute, so this thesis introduces the conception of Temporal GIS, Which provide information of changing procedure for the whole as well as a single ancestor land in a certain time period and can make historic data appear againoThe main content in this thesis is: How to improve the data manipulation automatization, How to storage the Soil Confiscation data which has time attribute, How to obtain more information by anlyzing Primary data. With LongQuan Section of ChengDu as an example ,this thesis firstly introduces the design of the LongQuan Section's Soil Confiscation Information System Database. Secondly, according to the characteristics of Soil Confiscation Information, this thesis gives methods to manage the spatial data and un-spatial data. Finally, VB and ArcGIS Engine are used to realize dynamic display of the Soil Confiscation status by time order, which can provide decision-making to leader, give management method to government, and offer decision-making sustain to society.
