Abstract

A lot of the data currently measured is measured based on indicators, but since the height value of the measurement point is not used as basic data, difficulties arise when trying to use it in a three-dimensional geographic information system. Various methods can be used to create polygons by drawing points on the surface using topographic information or extracting the height value of each measurement point on the surface in order to display large quantities on the surface. Among the various types of data expression methods, this study attempts a data construction and display method to improve visualization performance of time series measurement data expressed on the surface, and examines its procedures and strengths and weaknesses.

현재 측정되는 많은 데이터가 지표를 기반으로 측정되지만, 측정지점의 높이값이 기초자료로 활용되지 않기 때문에, 3차원 지리정보시스템에 활용하고자 할 때 어려움이 발생한다. 지표면에 많은 양을 표시하기 위해서는 지형정보를 이용하여 지표면에 점을 그리거나, 지표면의 각 측정지점의 높이값을 추출하여 다각형을 생성하는 방법이 다양하게 사용될 수 있다. 본 연구에서는 다양한 형태의 데이터 표현 방법 중 지표면에 표현되는 시계열 측정 데이터의 시각화 성능을 향상시키기 위한 데이터 구축 및 표시 방법을 시도하고, 그 절차와 장단점을 살펴본다.
