It's an absolute distance (in units of what's specified on the field type) that a grid square must maximally fit into (width & height). It can be used to to more explicitly specify the maximum grid square size without knowledge of what particular grid levels translate to. This can in turn be used with knowledge of the size of 'bbox' to get a target minimum number of grid cells. Mutually exclusive with distErrPct & gridLevel.
