将ArcGIS UTM转换为WGS84

本文关键字:WGS84 转换 UTM ArcGIS | 更新日期: 2023-09-27 18:29:54

我需要将UTM坐标(EPSG:23030,Datum ED50,30N,Ellipse Hayford 1924)转换为WGS84(用于在谷歌上渲染)。我正在尝试使用ArcGIS库,但没有得到预期的结果。这是我的代码(C#):

SpatialReference wgs84 = SpatialReference.Create(4326);
            MapPoint mp = ConvertCoordinate.FromUtm(string.Format("{0} {1} {2}", "30N", X, Y), wgs84, UtmConversionMode.None);

我想问题是我没有具体说明基准。

将ArcGIS UTM转换为WGS84

我解决了我的问题。C#代码:

public static void UTMToLatLongDSP(double X, double Y, out double latitude, out double longitude)
{
    double[] xy = new double[] { X, Y };
    MapPoint ptUTMED50 = new MapPoint(X, Y, new SpatialReference(23030));
    SpatialReference srTrans = new SpatialReference(4326);
    MapPoint ptWGS84 = (MapPoint)GeometryEngine.Project(ptUTMED50, srTrans);
    latitude = ptWGS84.Y;
    longitude = ptWGS84.X;
}
