coordconv

• Translates coordinate systems to and from each other. The coordinate system has the code below.
• 좌표계를 상호 변환합니다. 좌표계는 아래와 같은 코드를 가지고 있습니다.

How to Use

// let kk = coordconv(x, y, from, to)
//
// x : X axis of the coordinate system (ex:longitude)
//     좌표계의 X축 (예:경도)
// y : Y axis of the coordinate system (ex:latitude)
//     좌표계의 Y축 (예:위도)
// from : coordinate system code(from)
//        변환 대상 좌표계 코드
// to : coordinate system code(to)
//      변환 할 좌표계 코드
//
// return : transformed coordinates x,y (Array)
//          변환된 좌표의 x,y (배열)

let kk = coordconv(126.9876757,37.5611523,7,3)
// convert WGS84[7] (126.9876757,37.5611523) to WCONGNAMUL[3]
// WGS84 좌표계[7]의 좌표(126.9876757,37.5611523)를 WCONGNAMUL좌표계[3]로 변환한다.

console.log(kk) // [ 497278, 1128228 ]

Example

• Test code that converts WGS84 coordinates to other coordinates and back to WGS84 coordinates
• WGS84 좌표를 다른 좌표로 변환하고, 다시 WGS84 좌표로 변환시키는 테스트코드

for ( let k =0 ; k < 9; k++ ) {
    console.log(k)
    let kk = coordconv(126.9876757,37.5611523,7,k)
    coordconv(kk[0],kk[1],k,7)
}
