函数: simplify()

simplify<T>(geojson: T, options?: { tolerance?: number; highQuality?: boolean; mutate?: boolean; }): T

Function

Simplifies the geometries in a GeoJSON object. Uses the 2d version of simplify-js

.

类型参数

T

T extends AllGeoJSON

参数

geojson

T

GeoJSON object to be simplified

options?

Optional parameters

tolerance?

number

Simplification tolerance

highQuality?

boolean

Produce a higher-quality simplification using a slower algorithm

mutate?

boolean

Allow GeoJSON input to be mutated (significant performance improvement if true)

返回

T

Simplified GeoJSON
