Takes a GeoJSON Feature or FeatureCollection and truncates the precision of the geometry.
-
geojson
GeoJSON any GeoJSON Feature, FeatureCollection, Geometry or GeometryCollection. -
options
Object Optional parameters (optional, default{}
)-
options.precision
number coordinate decimal precision (optional, default6
) -
options.coordinates
number maximum number of coordinates (primarly used to remove z coordinates) (optional, default3
) -
options.mutate
boolean allows GeoJSON input to be mutated (significant performance increase if true) (optional, defaultfalse
)
-
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 layer with truncated geometry
This module is part of the Turfjs project, an open source module collection dedicated to geographic algorithms. It is maintained in the Turfjs/turf repository, where you can create PRs and issues.
Install this single module individually:
$ npm install @turf/truncate
Or install the all-encompassing @turf/turf module that includes all modules as functions:
$ npm install @turf/turf
