# Multipoint

An ordered collection of points that can be managed as a single geometry. Multipoint geometries represent an ordered collection of points. They can be used as the geometry of features and graphics, or as input or output for spatial operations. For features that consist of a very large number of points that share the same set of attribute values, multipoints may be more efficient to store and analyze in a geodatabase compared to using multiple point features.

A Multipoint is composed of a single read-only collection of Point. Use MultipointBuilder to build a multipoint one point at a time or to modify an existing Multipoint.

## Properties

The read-only collection of points for the multipoint. Use MultipointBuilder to build a multipoint one point at a time or to modify the points that compose an existing Multipoint.

## Inherited properties

Indicates the dimensionality of a Geometry, relating to the number of spatial dimensions in which the geometry may have a size. You can use Geometry.dimension to work out what kind of symbol can be applied to a specific type of geometry. For example, Point and Multipoint are both zero-dimensional point geometries, and both can be displayed using a type of MarkerSymbol. Polygon and Envelope are both 2-dimensional area geometries that can be displayed using a type of FillSymbol.

True if this geometry contains curve segments, false otherwise. ArcGIS software supports polygon and polyline geometries that contain curve segments (where Segment.isCurve is true, sometimes known as true curves or nonlinear segments). Curves may be present in certain types of data, such as Mobile Map Packages (MMPK) or geometry JSON. When connecting to ArcGIS feature services that support curves (see ArcGISFeatureServiceInfo.supportsTrueCurve), this API retrieves densified versions of curve feature geometries by default.

True if the geometry is empty, false otherwise. A geometry is empty if it does not have valid geographic coordinates, even if the SpatialReference is specified. An empty Geometry is a valid object that has no location in space.

The spatial reference for this geometry. This can be null if the geometry is not associated with a SpatialReference.

## Inherited functions

Checks if two geometries are approximately the same within the given tolerance. This function performs a lightweight comparison of two geometries that might be useful when writing test code. It uses the tolerance to compare each of x, y, and any other values the geometries possess (such as z or m) independently in the manner: abs(value1 - value2) <= tolerance. The single tolerance value is used even if the x, y, z or m units differ. This function does not respect modular arithmetic of spatial references which wrap around, so longitudes of -180 and +180 degrees are considered to differ by 360 degrees.
