Package Exports

@turf/truncate

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 (@turf/truncate) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

@turf/truncate

truncate

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

Parameters

geojson (FeatureCollection | Feature<any>) any GeoJSON Feature, FeatureCollection, Geometry or GeometryCollection.
precision [number] coordinate decimal precision (optional, default 6)
coordinates [number] maximum number of coordinates (primarly used to remove z coordinates) (optional, default 3)
mutate [boolean] allows GeoJSON input to be mutated (significant performance increase if true) (optional, default false)

Examples

var point = {
    "type": "Feature",
    "properties": {}
    "geometry": {
        "type": "Point",
        "coordinates": [
            70.46923055566859,
            58.11088890802906,
            1508
        ]
    }
};
var truncated = turf.truncate(point);

//addToMap
var addToMap = [truncated];

Returns (FeatureCollection | Feature<any>) layer with truncated geometry
