近兩天需要把平面坐標(biāo)轉(zhuǎn)換為標(biāo)準(zhǔn)的WGS84后使用百度逆地址編碼
搜索出資料記錄一下
- 類庫 程序ProjNet4GeoAPI
static void PtsToPts(ICoordinateSystem fromCS, ICoordinateSystem toCS,List<double[]> pts, out List<double[]> results)
{
CoordinateTransformationFactory ctfac = new CoordinateTransformationFactory();
ICoordinateTransformation trans = ctfac.CreateFromCoordinateSystems(fromCS, toCS);
results = trans.MathTransform.TransformList(pts);
}
static void Main(string[] args)
{
string bj1954Lcc= "……"; //見上文
IProjectedCoordinateSystem fromCS = CoordinateSystemWktReader.Parse(bj1954Lcc) as IProjectedCoordinateSystem;
GeographicCoordinateSystem toCS = GeographicCoordinateSystem.WGS84;
double[] xPts = new double[4] { 20634500, 20635500, 20634500, 20635500 };
double[] yPts = new double[4] { 4660000, 4660000, 4659000, 4659000 };
List<double[]> pts = new List<double[]>();
for (int i = 0; i < 4; i++)
{
double[] xy = new double[] { xPts[i], yPts[i] };
pts.Add(xy);
List<double[]> results = new List<double[]>();
PtsToPts(fromCS, toCS, pts, out results);
foreach (double[] result in results)
{
Console.WriteLine("{0},{1}", result[0], result[1]);
}
}
