@turf/truncate

truncate

Takes a GeoJSON Feature or FeatureCollection and truncates the precision of the geometry.

$3

* geojson [GeoJSON][1] any GeoJSON Feature, FeatureCollection, Geometry or GeometryCollection.
* options [Object][2] Optional parameters (optional, default {})

* options.precision [number][3] coordinate decimal precision (optional, default 6)
* options.coordinates [number][3] maximum number of coordinates (primarly used to remove z coordinates) (optional, default 3)
* options.mutate [boolean][4] allows GeoJSON input to be mutated (significant performance increase if true) (optional, default false)

``javascript
var point = turf.point([
70.46923055566859,
58.11088890802906,
1508
]);
var options = {precision: 3, coordinates: 2};
var truncated = turf.truncate(point, options);
//=truncated.geometry.coordinates => [70.469, 58.111]

//addToMap
var addToMap = [truncated];
`

Returns [GeoJSON][1] layer with truncated geometry
