시공간 개인통행자료의 지리적 시각화 = Geovisualization Environment for Spatio - temporal Trajectory of Personal Activity

국문 초록 (Abstract)

이 연구는 GPS 수신기를 통해 수집된 개인통행자료를 이용하여 통행패턴의 시공간적 특성을 다양한 그래픽으로 요약하고 탐색적 분석을 가능케하는 지리적 시각화 환경을 제안하고 이를 구현 및 평가하는 것을 목적으로 한다. 이 연구에서는 시공간입방체(space-time cube)를 바탕으로 시간지리학 개념을 시각적으로 표현하였으며, 시간산포기둥(temporal dispersion cylinder), 평행평면그림(parallel plane plot)과 같은 부가적인 시각화 도구의 구현을 통해 개인통행패턴의 시공간적 속성 및 이동경로 주위지역의 사회경제적·자연적 속성을 함께 탐색할 수 있도록 하였다. 또한 사용자와의 상호작용을 통해 개인통행자료에 포함되어 있는“언제”, “어디에서”, “무엇을”이라는 세 가지 정보요소들을 동적으로 탐색 및 질의할 수 있는 환경을 제공한다.

다국어 초록 (Multilingual Abstract)

This study attempts at prototyping and evaluating a geovisualization tool that summarizes and explores human activity patterns using spatio-temporal trajectory data collected from GPS receiver. A set of core conceptualization developed in “time geography” is successfully represented by our prototype based on the notion of “space-time cube.” The notions of “temporal dispersion cylinder” and “parallel plane plot” are also implemented to allow further analyses of human activity pattern on the space-time trajectory. The capabilities of the geovisualization environment we proposed include the interactive and dynamic functions that support a variety of explorations on the three components of spatio-temporal data : space(where), time(when), and object(what).
