# Module: RGeo::Feature::MultiPoint

- Extended by:
- Type

- Includes:
- GeometryCollection

- Included in:
- Cartesian::MultiPointImpl, Geographic::ProjectedMultiPointImpl, Geographic::SphericalMultiPointImpl, Geos::CAPIMultiPointImpl, Geos::FFIMultiPointImpl

- Defined in:
- lib/rgeo/feature/multi_point.rb

## Overview

## SFS 1.1 Description

A MultiPoint is a 0-dimensional GeometryCollection. The elements of a MultiPoint are restricted to Points. The Points are not connected or ordered.

A MultiPoint is simple if no two Points in the MultiPoint are equal (have identical coordinate values).

The boundary of a MultiPoint is the empty set.

## Notes

MultiPoint is defined as a module and is provided primarily for the sake of documentation. Implementations need not necessarily include this module itself. Therefore, you should not depend on the kind_of? method to check type. Instead, use the provided check_type class method (or === operator) defined in the Type module.
