PointArray

Constructors

constructor

new PointArray(coords, validity?): PointArray
Parameters
- coords: CoordBuffer
- Optional validity: BooleanArray
Returns PointArray
- Defined in esm/index.d.ts:757

Methods

affine_transform

affine_transform(transform): GeometryArray
Parameters
- transform: BroadcastableAffine
Returns GeometryArray
- Defined in esm/index.d.ts:684

area

area(): FloatArray
Returns FloatArray
- Defined in esm/index.d.ts:688

center

center(): PointArray
Returns PointArray
- Defined in esm/index.d.ts:692

centroid

centroid(): PointArray
Returns PointArray
- Defined in esm/index.d.ts:696

convex_hull

convex_hull(): PolygonArray
Returns PolygonArray
- Defined in esm/index.d.ts:700

euclidean_length

euclidean_length(): FloatArray
Calculation of the length of a Line

Returns FloatArray
- Defined in esm/index.d.ts:783

free

free(): void
Returns void
- Defined in esm/index.d.ts:679

geodesic_area

geodesic_area(): FloatArray
Returns FloatArray
- Defined in esm/index.d.ts:704

geodesic_area_signed

geodesic_area_signed(): FloatArray
Returns FloatArray
- Defined in esm/index.d.ts:708

geodesic_length

geodesic_length(): FloatArray
Determine the length of a geometry on an ellipsoidal model of the earth.

This uses the geodesic measurement methods given by Karney (2013). As opposed to older methods like Vincenty, this method is accurate to a few nanometers and always converges.

Returns FloatArray
- Defined in esm/index.d.ts:768

haversine_length

haversine_length(): FloatArray
Determine the length of a geometry using the haversine formula.

Note: this implementation uses a mean earth radius of 6371.088 km, based on the recommendation of the IUGG

Returns FloatArray
- Defined in esm/index.d.ts:778

is_empty

is_empty(): BooleanArray
Returns BooleanArray
- Defined in esm/index.d.ts:712

reproject_rs

reproject_rs(definition, direction): GeometryArray
Parameters
- definition: string
- direction: number
Returns GeometryArray
- Defined in esm/index.d.ts:718

rotate

rotate(angle, origin): GeometryArray
Parameters
- angle: BroadcastableFloat
- origin: TransformOrigin
Returns GeometryArray
- Defined in esm/index.d.ts:724

scale

scale(xfact, yfact, origin): GeometryArray
Parameters
- xfact: BroadcastableFloat
- yfact: BroadcastableFloat
- origin: TransformOrigin
Returns GeometryArray
- Defined in esm/index.d.ts:731

signed_area

signed_area(): FloatArray
Returns FloatArray
- Defined in esm/index.d.ts:735

skew

skew(x_degrees, y_degrees, origin): GeometryArray
Parameters
- x_degrees: BroadcastableFloat
- y_degrees: BroadcastableFloat
- origin: TransformOrigin
Returns GeometryArray
- Defined in esm/index.d.ts:742

to_ffi

to_ffi(): FFIArrowArray
Returns FFIArrowArray
- Defined in esm/index.d.ts:746

translate

translate(x_offset, y_offset): GeometryArray
Parameters
- x_offset: BroadcastableFloat
- y_offset: BroadcastableFloat
Returns GeometryArray
- Defined in esm/index.d.ts:752

vincenty_length

vincenty_length(): FloatArray
Determine the length of a geometry using Vincenty’s formulae.

Returns FloatArray
- Defined in esm/index.d.ts:790
