environmentaltools.spatial.rotate_coords

environmentaltools.spatial.rotate_coords(x, y, angle)[source]

Rotate coordinates by specified angle around the origin.

Performs 2D coordinate rotation transformation using angle specified in degrees. Rotation is counterclockwise for positive angles.

Parameters:

  • x (float or np.ndarray) – X coordinate(s) to rotate

  • y (float or np.ndarray) – Y coordinate(s) to rotate

  • angle (float) – Rotation angle in degrees. Positive values rotate counterclockwise.

Returns:

  • x_rot (float or np.ndarray) – Rotated X coordinate(s)

  • y_rot (float or np.ndarray) – Rotated Y coordinate(s)

Examples

>>> import numpy as np
>>> x, y = 1.0, 0.0
>>> x_rot, y_rot = rotate_coords(x, y, 90)  # Rotate 90 degrees
>>> print(f"({x_rot:.2f}, {y_rot:.2f})")
(0.00, 1.00)
