Simplification method

?
A modified version of Visvalingam simplification. Points located at the vertex of more acute angles are preferentially removed.

Other options

?
Remove line intersections. Works by rolling back simplification along intersecting segments.
?
Prevent small polygons from disappearing at high simplification. Protects the largest ring of multi- ring features.
coordinate precision
?
Rounding coordinates can fix topology problems in some files and reduces the size of GeoJSON files. Uses same units as the source file, e.g. decimal degrees for most unprojected files.
