pyacs.lib.coordinates.vel_xyz_to_enu.vel_xyz_to_enu(vel_xyz, approx_xyz=None, approx_lon_lat=None)

Converts a velocity expressed in geocentric cartesian coordinates (X, Y, Z) into local North, East, Up components (dN, dE, dU) at a reference point.

Parameters:

• vel_xyz – velocity in geocentric cartesian coordinates (meters)

• approx_xyz – reference point for the local frame in geocentric cartesian coordinates

• approx_lon_lat – reference point for the local frame in geographical coordinates (decimal degree)

Returns:

Venu
