lawn_tesselate: Tesselate

In lawn: Client for 'Turfjs' for 'Geospatial' Analysis

Description

Tesselates a data-Polygon into a data-FeatureCollection of triangles using earcut (github.com/mapbox/earcut)

Usage

lawn_tesselate(polygon, lint = FALSE)

Arguments

polygon	Input data-Feature<(data-Polygon)>
lint	(logical) Lint or not. Uses geojsonhint. Takes up increasing time as the object to get linted increases in size, so probably use by default for small objects, but not for large if you know they are good geojson objects. Default: FALSE

Value

A data-FeatureCollection
