Implementation Plan of Convergence Thematic Map for Activated Utilization of Cadastral Public Data

摘要

Data currently provided through the public data portal is relatively underused compared to the amount of data provided, due to difficulties in reprocessing the data for use. In this study, to solve the problems caused by such reprocessing work as well as maximize the use of public data,an implementation plan for a thematic map, in which highly demanded public data and cadastral information are combined, was presented. In this study, the implementation plan of the traffic accident status map, the floating population status map, and the land value change status map was presented,and judging by the result of the error analysis on the implemented thematic map, it appeared that there was no problem with providing it as public data. Since users can directly use the convergence thematic map implemented in this study without any reprocessing work, it is expected that itwill promote public data use.
