공간정보 오픈 플랫폼을 활용한 객체별 일조시간 산정 기법에 관한 연구

Abstract

Today, due to urban growth and high population density, building forests are formed in many large cities and therefore there is growing concern about the encroachment of the sunlight because of increasing demands for a pleasant residential environment. While the research on related law and related fields have begun to be carried out, there is a limit to the extent to which the public easily grasp the sunlight per building object without referral to a specialized agency. Therefore, in this study, the duration of sunlight for each building object is calculated through simulation of urban shaded area using spatial information open platform API. The study area is ‘L’ apartment complex located in Haeundae, Busan. For this purpose, the building height is extracted from the pre-built three-dimensional spatial information data, and the position of the sun is determined through the calculation of the altitude and azimuth of the sun to perform the duration of sunlight simulation for the three-dimensional urban spatial objects. In this paper, we aim to provide a more precise and easier method of judging infringement of sunlight by quantitatively analyzing the sunlight and classifying the total duration of sunlight and the continuous duration of sunlight each object.
