extent

An extent is a bounding rectangle with points that delineate an area for a mapA map is a collection of layers that are displayed in 2D. It is typically composed of a basemap layer and data layers.Learn more or sceneA scene is a collection of layers that are displayed in 3D. It is typically composed of a basemap layer, data layers, and 3D data.Learn more. It is typically used to represent the visible area of map or scene, but can also be used for geometric and spatial operations. The sides of an extent are aligned with the axes of the extent's spatial referenceA spatial reference is a set of parameters, typically defined by a WKID, that define the coordinate system and spatial properties for geographic data. Applications use a spatial reference to correctly display the position of geographic data in a map or scene.Learn more.
