Usage

wkt

import { WKT } from "geojson-converter-kit";

const wktStr = WKT.stringify({
  type: "Point",
  coordinates: [100.0, 0.0],
});

const geometry = WKT.parse(wktStr);

stringify - convert geojson to wkt

args | name | type | nullable | | --- | --- | --- | | geometry | GeoJSON.Geometry | false | | includeZ | boolean | true, default false |

parse - convert wkt to geojson

args | name | type | nullable | | --- | --- | --- | | wkt | string | false |

kml

import { KML } from "geojson-converter-kit";

const kmlStr = KML.stringify([
  {
    type: "Feature",
    properties: {},
    geometry: {
      type: "Point",
      coordinates: [100.0, 0.0],
    },
  },
]);

const features = KML.parse(kmlStr);

stringify - convert geojson to kml

args | name | type | nullable | | --- | --- | --- | | data | GeoJSON.FeatureCollection | Array<GeoJSON.Feature> | false | | options | KML.Stringify.Options | true, default {} |

KML.Stringify.Options | name | type | nullable | | --- | --- | --- | | name | string | true | | description | string | true |

parse - convert kml to geojson

args | name | type | nullable | | --- | --- | --- | | kml | string | false |

shpfile

import { SHPFILE } from "geojson-converter-kit";

const zipBlob = await SHPFILE.writeToZip([
  {
    type: "Feature",
    properties: {},
    geometry: {
      type: "Point",
      coordinates: [100.0, 0.0],
    },
  },
]);

const featureMaps = await SHPFILE.readFromZip(zipBlob);
