Accessors

geometryType

hasM

  • get hasM(): boolean
  • set hasM(hasM: boolean): void
  • Does the geometry have m coordinates

    Returns boolean

    true if has m coordinates

  • Set if the geometry has m coordinates

    Parameters

    • hasM: boolean

      true if has m coordinates

    Returns void

    true if has m coordinates

hasZ

  • get hasZ(): boolean
  • set hasZ(hasZ: boolean): void
  • Does the geometry have z coordinates

    Returns boolean

    true if has z coordinates

Methods

addRing

addRings

copy

equals

expandEnvelope

getCentroid

  • Get the mathematical centroid point of a 2 dimensional representation of the Geometry (balancing point of a 2d cutout of the geometry). Only the x and y coordinate of the resulting point are calculated and populated. The resulting {@link Point#getZ()} and {@link Point#getM()} methods will always return null.

    Returns Point

    centroid point

getDegreesCentroid

  • getDegreesCentroid(): Point
  • Get the geographic centroid point of a 2 dimensional representation of the degree unit Geometry. Only the x and y coordinate of the resulting point are calculated and populated. The resulting {@link Point#getZ()} and {@link Point#getM()} methods will always return null.

    Returns Point

    centroid point

getDimension

  • getDimension(): number

getEnvelope

getExteriorRing

getInteriorRing

getRing

  • getRing(n: number): Curve

isEmpty

  • isEmpty(): boolean

isMeasured

  • isMeasured(): boolean

isSimple

  • isSimple(): boolean

numInteriorRings

  • numInteriorRings(): number

numRings

  • numRings(): number

updateZM

Static hasM

  • hasM(geometries: Array<Geometry>): boolean
  • Determine if the geometries contain a M value

    Parameters

    Returns boolean

    true if has m

Static hasZ

  • hasZ(geometries: Array<Geometry>): boolean
  • Determine if the geometries contain a Z value

    Parameters

    • geometries: Array<Geometry>
