truncate

Description

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

Parameters

NameTypeDescription
geojsonGeoJSONany GeoJSON Feature, FeatureCollection, Geometry or GeometryCollection.
options?ObjectOptional parameters (default {})
options.precision?numbercoordinate decimal precision (default 6)
options.coordinates?numbermaximum number of coordinates (primarly used to remove z coordinates) (default 3)
options.mutate?booleanallows GeoJSON input to be mutated (significant performance increase if true) (default false)

Returns

    GeoJSON layer with truncated geometry

Examples

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]
