Primary LanguageC#

坐标转换

这是一个C#编写的用于坐标转换的项目,包括：

  1. 四参数转换
  2. 三参数转换
  3. 七参数转换(布尔沙模型)
  4. 大地坐标空间坐标互转
  5. 高斯正反算(在**一般把X轴向东移动500km,本程序将带号也加在了Y坐标前面)
  6. 一些常见的曲率半径计算

支持的参考椭球:

  1. WGS84
  2. CGCS2000
  3. 西安80(国际1975椭球)

coordinate-trans

This is a repo that doing some Geomatics coordinate transform by C#, Including:

  1. Four-parameter coordinate transformation
  2. Three-parameter coordinate transformation
  3. Seven-parameter coordinate transformation(Bursa)
  4. BLH to XYZ and XYZ to BLH
  5. Gauss Positive and Inverse calculation(In China,X aixs move 500 kilometers to West and the number of Zone is included in Y)
  6. I do not know how to express some function in English, XD(Calculation of M, N, R, Ra)

Supporting earth ellipsoid parameter as follow:

  1. WGS84
  2. CGCS2000
  3. Xi'an 80(international ellipsoid 1975)
