cartopy.img_transform.mesh_projection(projection, nx, ny, x_extents=(None, None), y_extents=(None, None))[source]#

Return sample points in the given projection which span the entire projection range evenly.

The range of the x-direction and y-direction sample points will be within the bounds of the projection or specified extents.

Parameters:

  • projection – A Projection instance.

  • nx (int) – The number of sample points in the projection x-direction.

  • ny (int) – The number of sample points in the projection y-direction.

  • x_extents (optional) – The (lower, upper) x-direction extent of the projection. Defaults to the x_limits.

  • y_extents (optional) – The (lower, upper) y-direction extent of the projection. Defaults to the y_limits.

Returns:

A tuple of three items. – The x-direction sample points numpy.ndarray of shape (nx, ny), y-direction sample points numpy.ndarray of shape (nx, ny), and the extent of the projection range as (x-lower, x-upper, y-lower, y-upper).
