Abstract

In this study, we analyze the current state of cadastral data in terms of accuracy and availability in order to improve the practical use of cadastre information as national framework data, draw out implications for social demand, implications of technology environment change. At present, cadastral information has been reduced in its role as land location in accordance with the conversion to the road name address, but it is receiving new value creation due to the fourth industrial revolution. In this situation, we proposed four ways to improve the availability of cadastre information. First, increpancy is defined as a spatial quality measure of cadastral information. Second, we provide a continuous cadastral map with improved location accuracy by matching it with the actual topography. Third, we should be providing a set of digital map consisting of a continuous cdmfadastral map, an address map, an aerial photograph, and a DEM. Fourth, to visualize the crowd sourcing data, it is necessary to construct and provide cadastre grid which is merged with 900㎡-1,000㎡ size. Based on this, if we build a service that finds and provides a new cadastral information service model, it can be expected to gradually improve its utilization, which will lead to improvement of the quality of cadastre information itself.
