Function coord_transforms::geo::ecef2lla

source · 
pub fn ecef2lla(
    ecef_vec: &Vector3<f64>,
    ellipsoid: &geo_ellipsoid
) -> Vector3<f64>
Expand description

Converts 3-d ECEF coordinates to 3-d LLA coordinates

Arguments

  • ecef_vec - Vector3 reference to the ECEF vector (x, y, z)
  • ellipsoid - geo_ellipsoid reference to the ellipsoid

Return Value

  • nalgebra::Vector3<f64> - lat, long, alt (radians, radians, meters)

Formula

  • x = arctan((z + e’^2 * b * sin^3 (theta)) / (p - e^2 * a * cos^3 (theta)))
  • y = arctan(y / x)
  • z = (p / cos(lat)) - N
