A COST ESTIMATION FOR COMPLETING THE CADASTRAL SURVEY OF JAPAN AND A STUDY OF PROMOTION MEASURES

Abstract

 The Cadastral Survey of Japan has been conducted since 1951, yet the area-based progress is 52% of the area of interest. There are 138,361 square kilometers left to survey, and the requiring cost of survey and duration are unknown. Firstly, this research summarizes the background of why such a large-scale cadastral survey is necessary for Japan, as well as its problematic effects to reinforce the importance of the completing the Cadastral Survey as a fundamental national project. Secondary and more importantly, the remaining project cost estimation is conducted based on available GIS and fixed-property tax data, with the common cost estimation method specified in the Cadastral Surveying Cost Estimation Standard book. The results show the estimated requiring cost to be 6.43 trillion yen, and with the current annual budget, it will take next 243 years until the completion. Considering the practicality of the project, this article discusses possibilities of promotion measures.
