Abstract

An array DBMS has been expected widely from scientists because it is convenient to store and analyze the data of array type. In this paper, we describe how to handle satellite remote-sensing images in the array DBMS. However, previous works in their visualization have two problems as follows. First, the images are visualized as a state of distorted by the curvature of the earth. Second, it is difficult to apply the results of visualization by pre-written queries to other analyses. Therefore, this paper proposes a three dimensional visualization method of satellite remote-sensing images, not traditional 2D visualization. Our research contents are as follows. First, we describe how to store, process, and analyze the satellite remote-sensing images in the array DBMS. Second, we propose a three-dimensional visualization method for their processed outputs. Lastly, our contributions can be summarized that we propose a method of handling satellite remote-sensing images in the array DBMS and their 3D visualization techniques. It is also expected that their use be available widely in many industrial areas.

배열형 DBMS는 배열형 자료의 저장 및 분석이 가능하므로 과학자들로부터 많은 기대를 받고 있다. 본 논문은 배열형 DBMS를 이용하여 위성원격탐사 영상을 처리하는 방법의 기술이다. 하지만 기존의 연구 방법들은 크게 두 가지 문제가 있다. 첫째, 지구곡률 등에 의해 왜곡된 데이터가 그대로 시각화되는 문제를 가진다. 둘째, 기 작성된 질의를 통해 얻어진 시각화 결과를 다른 분석에 활용하기 어렵다. 따라서 본 논문은 이런 문제점을 해소하고 더 나아가 기존의 2차원 시각화가 아닌 위성원격탐사 영상의 3차원 시각화 방법을 제안한다. 아울러 논문의 세부적인 연구내용은 다음과 같다. 첫째, 위성원격탐사 영상을 배열 데이터베이스에 저장, 분석, 가공하는 방법을 기술한다. 둘째, 가공된 결과물의 3차원 시각화 방법을 제안한다. 마지막으로 본 논문의 학술적 기여도는 배열형 DBMS에서의 위성원격탐사 영상의 활용 방법과 함께 위성데이터의 3차원 시각화 기법을 제안했고, 위성원격탐사 영상의 활용범위 확대에 기여할 것으로 요약된다.
