Accessors

geometryType

hasM

    Parameters

    • hasM: boolean

    • hasZ: boolean

      true if has z coordinates

    Returns void

    true if has z coordinates

is3D

Methods

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

isEmpty

  • isEmpty(): boolean

isMeasured

  • isMeasured(): boolean

isSimple

  • isSimple(): boolean

updateZM

Static hasM

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

    Parameters

    • geometries: Array<Geometry>

      list of geometries

    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>

      list of geometries

    Returns boolean

    true if has z
