API Reference

Terraformer

Terraformer.wktToGeoJSON(WKT) ⇒ object

Converts a WKT geometry into a GeoJSON geometry.

Kind: static method of Terraformer
Returns: object - GeoJSON.

import { wktToGeoJSON } from "@terraformer/wkt"

wktToGeoJSON("POINT (-122.6764 45.5165)");

>> { "type": "Point", "coordinates": [ -122.6764, 45.5165 ] }
Param Type Description
WKT string The input WKT geometry.

Terraformer.geojsonToWKT(GeoJSON) ⇒ string

Converts a GeoJSON geometry or GeometryCollection into a WKT string.

Kind: static method of Terraformer
Returns: string - WKT.

import { geojsonToWKT } from "@terraformer/wkt"

const geojsonPoint = {
  "type": "Point",
  "coordinates": [-122.6764, 45.5165]
}

geojsonToWKT(geojsonPoint)

>> "POINT (-122.6764 45.5165)"
Param Type Description
GeoJSON object The input GeoJSON geometry or GeometryCollection.
