.. py:function:: coordinates_conversion(coords, epsg_in, epsg_out)

   Convert coords from a SRS to another one.
   :param coords: coords to project
   :type coords: numpy array of 2D coords  (shape  (2,) or (N,2) or 3D coords (shape  (3,) or (N,3))
   :param epsg_in: EPSG code of the input SRS
   :type epsg_in: int
   :param epsg_out: EPSG code of the output SRS
   :type epsg_out: int
   :returns: converted coordinates
   :rtype: numpy array of 2D coord (N,2) or 3D coords (N,3)


.. py:function:: transform_index_to_physical_point(transform, row, col)

   Transform index to physical point

   :param row: row index
   :type row: float or 1D np.ndarray
   :param col: col index
   :type col: float or 1D np.ndarray
   :param transform: Affine function for georeference
   :type transform: Affine
   :return: Georeferenced coordinates (row, col)
   :rtype: Tuple(georeference row float or 1D np.ndarray, georeference col float or 1D np.ndarray)


.. py:function:: transform_physical_point_to_index(trans_inv, row_geo, col_geo)

   Transform physical point to index

   :param row_geo: physical point row
   :type row_geo: float or 1D np.ndarray
   :param col_geo: physical point col
   :type col_geo: float or 1D np.ndarray
   :param trans_inv: Affine function for georeference
   :type trans_inv: Affine
   :return: index coordinates (row, col)
   :rtype: Tuple(row float or 1D np.ndarray, col float or 1D np.ndarray)
