polyline-clean v3.0.1
polyline-clean 
Clean polyline or polygon data: remove duplicate, collinear, null points, etc.
const c = require('polyline-clean')
// remove duplicate, degenerate or collinear segments
c([[0,0], [null,null], [1,1], [1,1], [.5,.5], [1,1], [3,3]])
// === [[0,0], [3,3]]c(coordinates, options?)
Return new coordinates array with bad points removed. If result is degenerate, null will be returned.
| Option | Meaning |
|---|---|
ids | Return indexes in the initial array instead of points. |
fold | Collapse collinear segments. Can be a number indicating min angle threshold. polygon mode has more rigid folding. Useful to disable it when data has logarithmic fashion. |
polygon | Apply polygon optimizations: remove coinciding end, collinear end segments, ignore degenerate results. |
