Function: getGeometryCollection()

getGeometryCollection(__namedParameters): Promise<GeometryCollection>

Defined in: core/src/geometry/utils.ts:189

Get GeometryCollection from input geometries. The input geometries can be

1. GeoJSON features
2. binary feature collections
3. point layer data
4. arc layer data
5. hexagon id layer data

Parameters

__namedParameters

convertToUTM?

boolean = false

convert to UTM

fixPolygon?

boolean = true

fix polygon

geometries

SpatialGeometry

input geometries see SpatialGeometry

Returns

Promise<GeometryCollection>

GeometryCollection - the geometry collection used in GeoDaLib see src/spatial_features.h

Example

const geoms = [
  { type: 'Feature', geometry: { type: 'Polygon', coordinates: [[[0, 0], [1, 0], [1, 1], [0, 1], [0, 0]]] }, properties: { index: 0 } },
];
const geometryCollection = await getGeometryCollection({ geometries: geoms });
