  • The Public Noticed Land Price system was developed in order to establish a practical and consistent land price information system, where land prices are appraised and publicly noticed according to the Law Governing the Public Notice of Real Estate Prices and Appraisals.The appraisal process for evaluating and appraising the public noticed land price in conducted in phases, where the nation's land is divided into human and spatial portions according to administrative districts. Depending on the subjective judgement of the appraiser, it is therefore possible for discrepancies to occur in land prices for lots near the boundaries of administrative districts. There is the computerized support system to maintain the public noticed land prices balance between the boundaries of cities, counties, and districts (the units in which evaluation and appraisal are conducted to determine public noticed land prices). But, due to that system is divided into attribute and spatial data information, it is possible for discrepancies to occur in land prices for lots near the boundaries of administrative districts. The purpose of this study to suggest the reasonable methods on discrepancies in public noticed land prices through spatial analysis using GIS.

  • 본 연구는 지가의 공간분포 분석(spatial data analysis)을 통하여 합리적인 표준지 선정 방안을 제시하고자 하였다. 우리나라의 경우 개별 공시지가는 표준지 공시지가로부터 비교해서 산정된다. 때문에, 표준지는 개별지의 지가를 산정하는데 편리할 수 있도록 선정되어야 한다. 이를 위하여 표준지를 선정할 때, 개별지의 지가와 토지특성을 고려하여 표준지의 수와 공간적 분포를 결정하여야 한다. 본 연구에서는 지가의 공간적 분포를 해석하기 위하여 군집분석(cluster analysis) 개념을 활용하였다. 이를 통하여 유사 지가구획을 정의하였고, 지가구획의 계층적 해석을 시도하였다. 또한, 군집분석을 반복적으로 수행하고 군집수의 변화에 따른 군집별 지가분포의 특성을 해석함으로써 적정표준지 수를 추정하였다.

  • The Operational Linescan System (OLS)sensor is a sensor aboard satellites launched through the Defense Meteorological Satellite Program (DMSP) that detects light in the visible and infrared bands emitted at night. Studies by several researchers have shown a high correlation between nighttime light data from OLS sensors and gross domestic product values. In this study, we investigated the correlation of nighttime light data with the total amount of individual land prices, which is one of the various indicators related to economic development. The study found that most cities and provinces showed a high correlation with a correlation coefficient of more than 0.7, and the correlation coefficient of 0.7837 between the total amount of individual land price and nighttime light data for the entire South Korea was also high. However, unlike other cities and provinces, Seoul has a low correlation coefficient of 0.5648 between nighttime light and the total amount of individual land price, which is analyzed as a reason that the digital number value of the OLS sensor is close to the maximum value and cannot show further brightness changes. This study is expected to help identify announced land prices in areas where announced land prices are not systematically organized and to analyze land use changes in such areas.

  • The purpose of this study is to find out the methodologies, using GIS techniques, to appraise the parcel prices and to estimate the compensation expenditures according to road expansions. This study consists of 2 parts. The first pare is to find out the ways for appraisal of patrol prices in certain area by the publicly announced land prices. The second part is to estimate the differences of compensation expenditures according to road expansion methods. The conclusions are as follows. First, to appraise the target parcel prices, a comparison to the publicly announced land prices should be used. For this, 19 items of land characteristics of existing land information should be analyzed and compared using GIS techniques. Second, the compensation expenditure could be easily estimated using GIS techniques too. In this process, if necessary, we have to apply the minimum parcel size in Building Codes.

  • Officially assessed land price has been the index of South Korea since 1989 throughout different sectors of tax and welfare. Officially assessed land price is used as a tax valuation for the tax on property holdings, and the equity of such is the most important factor in the fair taxation for the people of South Korea. On this wise, this research analyzed and verified the horizontal and vertical inequity of officially assessed land price in Seoul by using the real transaction data between 2016 and 2018. In fact, Seoul's assessment ratio for the entire three-year period was 60.64% and it showed to increase each year. Horizontal equity was found to be most favorable in 2017, and the horizontal equity of each borough of Seoul appeared to improve each year. Vertical inequity was found to have reverse inequality in most boroughs of Seoul, however, some parts of Gangnam districts such as Gangnam-gu, Seocho-gu, and Gangdong-gu presented progressive inequality. Such example showed the need for improvement in terms of balance by each borough. The use of quantile regression demonstrated reverse inequality in most quantile, but, the differences in the value of the coefficient by each quantile showed the need for improvement of officially assessed land price with the equity of each quantile. Through the equity verification of officially assessed land price, it was analyzed that the lack of equity was found by year, by borough, and by use district. In order to redeem the lack of equity, the government must systematically supplement the real-estate disclosure system by initiating ratio studies to verify horizontal and vertical equity.

  • Urban area is being continuously grown traffic volume due to diverse economic activities. Especially, the traffic noise, which occurs on the road of passing by residential district, is dropping quality of life as negative element of obstructing sleep at night. This study analyzed relationship between the officially notified land price and the traffic noise in residential district by using the estimating equation of traffic noise and GIS. As a result, the officially notified land price on a parcel of residential district along the road was indicated to be higher than a parcel where is located in other place. Even traffic noise was indicated to be higher. Accordingly, a plan is judged to be necessarily arranged that can be made appraisal of the officially notified land price, which is reflected the convenience of life and the quality of life at the same time in consideration even of traffic noise together as element of appraisal given evaluating the officially notified land price in residential district where is located in the downtown.

  • This study has the purpose of suggesting the method to analyze the spatiotemporal change of satisfaction concerning the officially assessed land price using geostatistical analysis. Analyzing the spatial distribution characteristic of officially assessed land price using present GIS (Geographic Information System) or is staying at qualitatively suggesting the improvement method of the officially assessed land price system. Grouping the appeal strength based on the official price and opinion price of officially assessed land price, GIS DB (Database) was constructed and the time seriate satisfaction were analyzed and compared through spatial density analysis and spatial autocorrelation analysis. As a result, it was found that the difference between the official price and the applicant's price differed depending on individual land, but most of the respondents requested the increase or the reduction of the average land price, which resulted in a large number of request. Analyzing the satisfaction of the officially assessed land price by using GIS, it was known that satisfaction of officially assessed land price could be analyzed by using the difference of the opinion price and not only the officially assessed land price. Spatiotemporal change of officially assessed land price satisfaction was known to be possible through spatiotemporal pattern analysis method such as spatiotemporal auto-corelation analysis and hotspot analysis etc using GIS. In short, regionally positive or negative significant relationship was investigated through spatiotemporal analysis using annual data.
