This tool snaps points to the corners of a grid based on the input grid size.
The input point data that will be snapped to the centre of the grid.
The size of the grid in projected units to snap to. Units are in the projected units of the input layer.
An X offset for the grid in map units so the grid doesn't need to be centred around the 0, 0 location.
A Y offset for the grid in map units so the grid doesn't need to be centred around the 0, 0 location.
The output point layer that has the point geometries snapped to the corners of the grid defined by the grid size. The other attributes of the input dataset will be unchanged.
