3-D Coordinate and Vector Transformations

Transform coordinates and vector components between global and local systems; find intersection with spheroid

Transform 3-D coordinates between Earth-centered Earth-fixed (ECEF), geodetic, east-north-up (ENU), north-east-down (NED), and azimuth-elevation-range (AER) systems. Transform 3-D vector components between ECEF, ENU, and NED systems.

The type of transformation function you choose depends on your data. If your data represents position relative to the origin of a system, choose a coordinate transformation. If your data represents quantities such as velocity or acceleration, choose a vector transformation function.
