국가지점번호의 경위도좌표로의 변환방법

국가지점번호의 근간은 UTM-K(한국형 UTM 좌표계)임.   예] 나 바 9842 3400 [안면도 탕건봉의 위치] <img src="https://t1.daumcdn.net/cfile/cafe/2644B34C57B6547E0F" class="txc-image" width="930" style="clear: none; float: none;"

=> 13예시의 경우 ‘나’이므로 8이 된다   2. 첫번째 4자리 숫자에 0을 붙인다예시의 경우 98420이 된다   3. 1과 2의 결과를 순차로 합하면 898420이다. 이것은 UTM-K의 동향값(Easting)이다   4. 두번째 음절을 다음과 같이 변환한다가 => 13나 => 14다 => 15라 => 16마 => 17바 => 18사 => 19아 => 20예시의 경우 ‘바’이므로 18이 된다   5. 두번째 4자리 숫자에 0을 붙인다예시의 경우 34000이 된다   6. 4와 5의 결과를 순차로 합하면 1834000이다. 이것은 UTM-K의 북향값(Northing)이다.   7. <a href="http://map.ngii.go.kr/">http://map.ngii.go.kr/</a>국토정보플랫폼의
