Geometry.MultiSurfaceZM (Geometry v1.2.0)

A multi-surface struct, representing a 4D collection of surfaces.

A MultiSurface is a collection of surfaces which can include Polygons or CurvePolygons.

Summary

Types

surface()

t()

Functions

new()

Creates an empty MultiSurfaceZM.

new(surfaces, srid \\ 0)

Creates a MultiSurfaceZM from the given surfaces.

Types

surface()

@type surface() :: Geometry.PolygonZM.t() | Geometry.CurvePolygonZM.t()

t()

@type t() :: %Geometry.MultiSurfaceZM{srid: Geometry.srid(), surfaces: [surface()]}

Functions

new()

@spec new() :: t()

Creates an empty MultiSurfaceZM.

Examples

iex> Geometry.MultiSurfaceZM.new()
%Geometry.MultiSurfaceZM{surfaces: [], srid: 0}

new(surfaces, srid \\ 0)

@spec new([surface()], Geometry.srid()) :: t()

Creates a MultiSurfaceZM from the given surfaces.

Examples

iex> Geometry.MultiSurfaceZM.new([
