Gridded Surface

GriddedSurface (GridObject)

A GriddedSurface is a XY oriented elevation surface with fixed cell size between its points. The grid points are defined at its corners in the XY plane and the Z-value of the points are not constrained. Gridded surfaces cannot be multi-Z. The cells may not be contiguous and don't have to all be defined.

For instance, a gridded surface can be of shape 5 x 3 x 2 but only have 3 cells defined at [1, 2, 1], [1, 3, 1] and [2, 3, 1].

Grid shape and cell sizes are inferred from the X, Y geometry. The grid is assumed to be cartesian and to have a constant cell size.

Parameters:

Name	Type	Description	Default
name	str	object name.	required
xyz	~Data	cell corners of the gridded surface.	required
atol	float	absolute tolerance used to automatically calculate the cell dimension. It is the distance tolerance (same unit as xyz) to consider whether the dimensions of all cells can be considered equal. Defaults to 0.001.	0.001

Exceptions:

Type	Description
ValueError	Variable cell size is inferred.
ValueError	There is a single cell in one of the axes.
