如何在 NetTopologySuite 中通过米计算两个几何距离?

how to calculate two geometry distance via meters in NetTopologySuite?

我使用 PGSQL 获取几何数据。

 var hca = new WKTReader().Read(
        $"SRID=4326;{hcaShape}");
 var point = new GeometryFactory().CreatePoint(new Coordinate(x, y));
 var res = hca.Distance(point)

结果显示为:'0.00009xxx' 但是我要米

同样重要的是这种情况不是点对点。 如何将结果转换为米?(我是 NetTopologySuite 的新手)

我通过使用 ProjNet 将几何图形投影到度量 CoordinateSystem

来完成此任务
public static NetTopologySuite.Geometries.Geometry ProjectGeometry(NetTopologySuite.Geometries.Geometry geom,
    string fromWkt, string toWkt)
{
    var sourceCoordSystem = new CoordinateSystemFactory().CreateFromWkt(fromWkt);
    var targetCoordSystem = new CoordinateSystemFactory().CreateFromWkt(toWkt);

    var trans = new CoordinateTransformationFactory().CreateFromCoordinateSystems(sourceCoordSystem,
        targetCoordSystem);

    var projGeom = Transform(geom, transform: trans.MathTransform);

    return projGeom;
}
