wgs84转任意中央子午线cgcs2000 vba代码

以下是将WGS84坐标系转换为任意中央子午线CGCS2000坐标系的VBA代码：

Function WGS84ToCGCS2000(longitude As Double, latitude As Double, altitude As Double, centralMeridian As Double) As Variant
    Dim a As Double, b As Double, f As Double, e As Double, N As Double, X As Double, Y As Double, Z As Double
    Dim a0 As Double, a2 As Double, a4 As Double, a6 As Double, a8 As Double, M As Double, T As Double, C As Double, A As Double, B As Double, E As Double, W As Double, N0 As Double, K As Double
    Dim delta_X As Double, delta_Y As Double, delta_Z As Double, dX As Double, dY As Double, dZ As Double
    
    'WGS84椭球体参数
    a = 6378137
    f = 1 / 298.257223563
    b = a * (1 - f)
    e = Sqr(2 * f - f * f)
    
    'CGCS2000椭球体参数
    a0 = 6378137
    a2 = -0.000000000000000000000000000003405
    a4 = 0.000000000000000000000000001550
    a6 = -0.000000000000000000000000000004870
    a8 = 0.000000000000000000000000000000016
    
    '计算经纬度对应的参数
    N = a / Sqr(1 - e * e * Sin(latitude) * Sin(latitude))
    X = (N + altitude) * Cos(latitude) * Cos(longitude)
    Y = (N + altitude) * Cos(latitude) * Sin(longitude)
    Z = (N * (1 - e * e) + altitude) * Sin(latitude)
    
    '计算转换参数
    M = a0 * (1 - e * e) * (a0 * (1 - e * e) / (b * b) - 1)
    T = Tan(latitude)
    C = e * Cos(latitude) * Cos(latitude) / (1 - e * e)
    A = (longitude - centralMeridian) * Cos(latitude)
    B = latitude
    E = (a2 * Sin(2 * latitude) + a4 * Sin(4 * latitude) + a6 * Sin(6 * latitude) + a8 * Sin(8 * latitude)) / 10 ^ 6
    W = M / (a0 * (1 - e * e)) / (1 - e * e * Sin(latitude) * Sin(latitude))
    N0 = a0 / Sqr(1 - e * e * Sin(0) * Sin(0))
    K = 1 + (A * A / 2 + (5 - T * T + 9 * C + 4 * C * C) * A * A * A * A / 24 + (61 - 58 * T * T + T * T * T * T) * A * A * A * A * A * A / 720) * (B * B) / 10 ^ 6
    
    '计算坐标转换
    delta_X = -W * X + K + E
    delta_Y = -W * Y
    delta_Z = -W * Z
    
    dX = -delta_Y * Sin(centralMeridian) - delta_Z * Cos(centralMeridian)
    dY = delta_Y * Cos(centralMeridian) - delta_Z * Sin(centralMeridian)
    dZ = delta_X
    
    '返回结果
    WGS84ToCGCS2000 = Array(X + dX, Y + dY, Z + dZ)
End Function

这段代码会返回一个包含三个元素的数组，分别是转换后的X、Y、Z坐标。其中longitude、latitude、altitude分别为WGS84的经度、纬度和高度，单位为度和米；centralMeridian为目标坐标系的中央子午线经度，单位为度。需要注意的是，本代码仅适用于中国境内的坐标转换，如果需要进行其他地区的转换，需要根据实际情况进行修改。
