Instances of MapPoint can be created using a constructor that defines the full geometry by passing an x coordinate, y coordinate, and spatial reference. Optionally, a z-value (to define elevation, for example) can also be included. Points store a single set of x,y coordinates that represent a discrete location within a specified coordinate system (spatial reference). Points can be used as the geometry of features and graphics and are often used to help construct other geometries. Larger geographic entities such as cities are often represented as points on small-scale maps. MapPoint geometries represent a single point, place, or location such as a geocoded house address along a street or the location of a water meter in a water utility network. Geometry builders are designed to represent the state of a geometry under construction while allowing modifications, thus enabling editing workflows. While immutable geometries appear to present problems for editing existing geometries, those problems are solved by using geometry builders. They are inherently thread-safe, help prevent accidental changes, and allow for certain performance optimizations. Immutable geometries (geometries that cannot be changed) offer some significant benefits to your app. Examples include feature geometry created for storage in a geodatabase, read from a non-editable layer, or returned from tasks such as spatial queries, geocode operations, network traces, or geoprocessing. Most geometries are created and not changed for their lifetime. Geometries can be converted to and from JSON to be persisted or to be exchanged directly with REST services.Geometries can have z-values and/or m-values.Geometries can be empty, indicating that they have no specific location or shape.Geometries have a spatial reference indicating the coordinate system used by its coordinates.The following are common geometry characteristics: MapPoint, Multipoint, Polyline, Polygon, and Envelope all inherit from the Geometry base class, and represent different types of shapes. The Geometry class provides functionality common to all types of geometry.

They are also used as inputs and outputs of spatial analysis and geoprocessing operations, and to measure distances and areas, among other uses. They are used throughout the API to represent the shapes of features and graphics, layer extents, viewpoints, and GPS locations. Geometries represent real-world objects by defining a shape at a specific geographic location.
