pyinterp.geometry.satellite.calculate_swath(lon_nadir: numpy.ndarray[dtype=float64, shape=(*), writable=False], lat_nadir: numpy.ndarray[dtype=float64, shape=(*), writable=False], delta_ac: float, half_gap: float, half_swath: int, spheroid: pyinterp.core.geometry.geographic.Spheroid | None = None) → tuple[numpy.ndarray[dtype=float64, shape=(*, *), order='F'], numpy.ndarray[dtype=float64, shape=(*, *), order='F']]#

Calculate the swath coordinates from the nadir coordinates.

Parameters:

  • lon_nadir – Longitude of nadir in degrees.

  • lat_nadir – Latitude of nadir in degrees.

  • delta_ac – Across-track distance between two consecutive pixels (meters).

  • half_gap – Half of the gap between the nadir and the first pixel (meters).

  • half_swath – Half of the swath width (pixels).

  • spheroid – Optional spheroid model.

Returns:

Tuple of longitude and latitude matrices of the swath.
