Clean polygon or polyline coordinates: remove duplicates, collinear or degenerate segments, holes, trim etc.

Package Exports

  • polyline-clean

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (polyline-clean) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

polyline-clean experimental Build Status

Clean polyline or polygon data: remove duplicate, collinear, null points, etc.

npm install polyline-clean

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.
  • parse-poly − parse any polygon/polyline format and return list of coordinates.
  • simplify-path − simplify polyline with tolerance.
