Simplification
prevent shape removal
?
Prevent small polygon features from disappearing at high simplification. Keeps the largest ring of multi-ring features.
use planar geometry
?
Interpret x, y values as Cartesian coordinates on a plane, rather than longitude, latitude coordinates on a sphere.
Method
Douglas-Peucker
?
Simplified lines remain within a set distance of original lines. Good for thinning dense points, but spikes tend to form at high simplification.
Visvalingam / effective area
?
Lines are simplified by iteratively removing the point that forms the least-area triangle with two adjacent points.
Visvalingam / weighted area
?
Points located at the vertex of more acute angles are preferentially removed, for a smoother appearance.

Options
detect line intersections
?
Detect line intersections, including self-intersections, to help identify topological errors in a dataset.
snap vertices
?
Fix topology errors by snapping together points with nearly identical coordinates. This option does not apply to TopoJSON files.
