truncate

描述

🌐 Description

获取 GeoJSON 要素或要素集合,并根据几何体的精度进行截断。

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

参数

🌐 Parameters

名称类型描述
geojsonGeoJSON任何 GeoJSON 特性、特性集合、几何或几何集合。
options?Object可选参数 (默认 {})
options.precision?number坐标小数精度 (默认 6)
options.coordinates?number坐标的最大数量(主要用于移除 z 坐标)(默认 3)
options.mutate?boolean允许修改 GeoJSON 输入(如果为真,性能将显著提高)(默认 false)

返回

🌐 Returns

GeoJSON 带截断几何的图层

示例

🌐 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]
