概化
阻止形变
?
Prevent small polygon features from disappearing at high simplification. Keeps the largest ring of multi-ring features.
平面几何
?
Treat x, y values as Cartesian coordinates on a plane, rather than as longitude, latitude coordinates on a sphere.
方法
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.
