ArcGIS.Core.Geometry Namespace / SpatialReference Class / Domain Property

    Domain Property (SpatialReference)
    In This Topic
    Gets the square domain extent of the spatial reference.
    Syntax
    public Envelope Domain {get;}
    Public ReadOnly Property Domain As Envelope
    Remarks
    The domain extent is different than the valid area of a coordinate system. The domain extent is an arbitrary square used to delimit valid coordinates for a spatial reference system and determine their resolution. It is possible that the domain extent is larger than the usable area of a coordinate system (a UTM zone, for example).
