A WGS84 geography feature simplifier, based on simplify-js
npm install @mapbox/geosimplify-jsThis module simplifies sequences of [longitude,latitude] pairs using
geography-aware measurement thresholds.
Based on https://github.com/mourner/simplify-js, geosimplify-js
fixes the problem that the simple pythagorean measure used in simplify-js
changes size if you simply give it longitude/latitude sequences to
simplify.
Usage:
``javascript`
simplify([[lon,lat],[lon,lat],[lon,lat]], offsetThresholdInMetres, gapThresholdInMetres);
path - an array of longitude,latitude pairs
offsetThreshold - how far outside the straight line a point needs to be for it to be "kept"
gapThreshold - if removing a point would create a segment longer than this, do not remove it
Example:
`javascript``
var geosimplify = require('geosimplify');
var coords = [ [ 15.603332, 78.227070 ],
[ 15.606422, 78.226824 ],
[ 15.608782, 78.226667 ],
[ 15.610799, 78.226535 ] ];
var result = geosimplify(coords, 5, 50);
