Coordinate conversion
  1. Longdo Map API uses the World Geodetic System (WGS84) a coordinate can be converted using proj4js library
    proj4js
    var dms = longdo.Util.locationToDMS(location);
    • dms: Degrees Minutes Seconds format
    var utmZone = longdo.Util.locationToUTMZone(location);
    var utmProj = '+proj=utm +zone=' + utmZone.zone + (utmZone.hemisphere == 'S' ? ' +south' : '') + ' +datum=WGS84 +units=m +no_defs'
    var utmPoint = proj4(utmProj, [location.lon, location.lat])
    • ค่า utmZone: Universal Transverse Mercator system
    • ค่า utmProj: Projection that you want to convert
    • ค่า utmPoint: Coordinates that have been converted
    Example
    WGS84 (EPSG:4326)
    =
    =

    UTM (EPSG:32647, EPSG:32648)
    =
