hamsci_psws.geopack.lspToLcar(X, Y, Z, inverse=False)[source]

Converts a position from local spherical to local cartesian (and vice-versa).

The local spherical coordinate system is defined as:

  • origin: local position

  • azimuth (with respect to North)

  • Elevation (with respect to horizon)

  • Altitude

The local cartesian coordinate system is defined as:

  • origin: local position

  • X: East

  • Y: North

  • Z: up

The meaning of the input (X,Y,Z) depends on the direction of the conversion (to global cartesian or to global spherical).

Parameters

  • X (float) – azimuth [degree, N] or local cartesian X [km]

  • Y (float) – elevation [degree] or local cartesian Y [km]

  • Z (float) – distance origin [km] or local cartesian Z [km]

  • inverse (Optional[bool]) – inverse conversion

Returns

  • X (float) – local cartesian X [km] or azimuth [degree, N]

  • Y (float) – local cartesian Y [km] or elevation [degree]

  • Z (float) – local cartesian Z [km] or distance from origin [km]
