Function: getThiessenPolygons()

getThiessenPolygons(geoms): Promise<Feature<Geometry, GeoJsonProperties>[]>

Defined in: core/src/geometry/thiessen-polygon.ts:25

Get the Thiessen polygons for the given geometries. If the given geometries are not points, the centroids will be used to create the Thiessen polygons.

Note: The Thiessen polygons are the polygons that are created by the Voronoi diagram of the points.

Example

const geoms = [
  { type: 'Feature', geometry: { type: 'Point', coordinates: [-122.4194, 37.7749] } },
  { type: 'Feature', geometry: { type: 'Point', coordinates: [-74.0060, 40.7128] } },
  { type: 'Feature', geometry: { type: 'Point', coordinates: [-87.6298, 41.8781] } },
  { type: 'Feature', geometry: { type: 'Point', coordinates: [-95.3698, 29.7604] } },
];
const thiessenPolygons = await getThiessenPolygons({ geoms });

Parameters

geoms

The geometries to get the Thiessen polygons

geoms

SpatialGeometry

Returns

Promise<Feature<Geometry, GeoJsonProperties>[]>

The Thiessen polygons
