초록

이 해설에서는 물리탐사 및 지구물리 분야 실무자들의 측지 좌표계와 지도 투영에 관한 이해를 높이기 위해 이를 구성하는 요소들의 개념을 상세히 설명하였다. 지구 타원체, 지오이드, 지심 위도, 측지 위도, 경도, 항정선, 대원 등의 기본 개념을 자세히 설명하였다. 또한 현재 대표적으로 널리 사용되고 있는 지심 직각 좌표계, 경위도 좌표계에 대한 설명과 함께 좌표계 간의 좌표 변환에 대해서도 자세히 설명하였다. 이와 더불어 지역 측지 데이텀 변환 및 직각 좌표 투영에 대한 설명을 추가하고 우리나라 측지 좌표계에 대하여 요약하여 물리탐사 실무에서 좌표 체계를 더 잘 이해하고 사용할 수 있도록 하였다.

In this review, the basic concepts of geodetic coordinate system and map projection are explained to practitioners in exploration geophysicists to enhance the understanding of geographic and projected coordinate system. The fundamental elements such as earth ellipsoid, geoid, geocentric and geodetic latitudes, rhumb line, and great circle are dealt with in detail. The geocentric and geodetic coordinate systems are also summarized neatly, together with coordinate conversion formulae. In addition, the concept and technique for datum transforms between local and world datum are presented, with special emphasis on Korean Geodetic System.
