Coordinates will be rounded if the precision grid specified is less precise
than the input geometry. Duplicated vertices will be dropped from lines and
polygons for grid sizes greater than 0. Line and polygon geometries may
collapse to empty geometries if all vertices are closer together than
grid_size. Z values, if present, will not be modified.
``grid_size`` or if a polygon becomes significantly narrower than
``grid_size``. Spikes or sections in polygons narrower than ``grid_size``
after rounding the vertices will be removed, which can lead to multipolygons
or empty geometries. Z values, if present, will not be modified.
Note: subsequent operations will always be performed in the precision of
the geometry with higher precision (smaller "grid_size"). That same
precision will be attached to the operation outputs.
Notes:
Also note: input geometries should be geometrically valid; unexpected
results may occur if input geometries are not.

This parameter determines how to handle invalid output geometries. There are three modes:
This parameter determines the way a precision reduction is applied on
the geometry. There are three modes:
1. `'valid_output'` (default): The output is always valid. Collapsed geometry elements
(including both polygons and lines) are removed. Duplicate vertices are removed.
2. `'pointwise'`: Precision reduction is performed pointwise. Output geometry
may be invalid due to collapse or self-intersection. Duplicate vertices are not
removed. In GEOS this option is called NO_TOPO.

.. note::
'pointwise' mode requires at least GEOS 3.10. It is accepted in earlier versions,
but the results may be unexpected.
3. `'keep_collapsed'`: Like the default mode, except that collapsed linear geometry
elements are preserved. Collapsed polygonal input elements are removed. Duplicate
vertices are removed.
