Operations on geographical grid¶
-
octant.grid.cell_centres(bounds, bound_position=0.5)[source]¶ Calculate coordinate cell centres.
Inspired by SciTools iris package.
- Parameters
bounds (numpy.array) – One-dimensional array of cell boundaries of shape (M,)
bound_position (bool, optional) – The desired position of the bounds relative to the position of the points.
- Returns
centres – Array of shape (M+1,)
- Return type
numpy.array
Examples
>>> a = np.arange(-1, 3., 1.) >>> a array([-1, 0, 1, 2]) >>> cell_centres(a) array([-0.5, 0.5, 1.5])

octant.grid.cell_bounds(points, bound_position=0.5)[source]¶ Calculate coordinate cell boundaries.
Inspired by SciTools iris package.
- Parameters
points (numpy.array) – One-dimensional array of uniformy spaced values of shape (M,)
bound_position (bool, optional) – The desired position of the bounds relative to the position of the points.
- Returns
bounds – Array of shape (M+1,)
- Return type
numpy.array
Examples
>>> a = np.arange(-1, 2.5, 0.5) >>> a array([-1. , -0.5, 0. , 0.5, 1. , 1.5, 2. ]) >>> cell_bounds(a) array([-1.25, -0.75, -0.25, 0.25, 0.75, 1.25, 1.75, 2.25])
