truncate
Description
Takes a GeoJSON Feature or FeatureCollection and truncates the precision of the geometry.
Parameters
| Name | Type | Description |
|---|---|---|
| geojson | GeoJSON | any GeoJSON Feature, FeatureCollection, Geometry or GeometryCollection. |
| options? | Object | Optional parameters (default {}) |
| options.precision? | number | coordinate decimal precision (default 6) |
| options.coordinates? | number | maximum number of coordinates (primarly used to remove z coordinates) (default 3) |
| options.mutate? | boolean | allows 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]
