    Classes
     ClassDescription
    ClassRepresents an angular unit of measure used by a Geometry or SpatialReference, or in measurement conversion functions.
    Class Represent an area unit of measure.
    ClassA Material class describing basic graphic properties.
    ClassA composite geographic transformation class is an ordered list of GeographicTransformation classes. The geographic transformations are applied in the order they are stored.
    ClassA composite hv (horizontal/vertical) datum transformation class is an ordered list of HVDatumTransformation classes. The hv datum transformations are applied in the order they are stored.
    Class Provides the well-known ID (WKID), name and category (or region) of a particular coordinate system.
    ClassA builder for creating a CubicBezierSegment whose methods can be called on any thread.
    ClassRepresents a third degree cubic Bezier curve for use in a Multipart geometry. To create a cubic bezier segment use the CubicBezierBuilderEx object.
    ClassDescribes the horizontal datum of a geographic coordinate system. It is returned from SpatialReference.Datum.
    ClassAn abstract class for datum transformations. Currently, a datum transformation can be a GeographicTransformation, a CompositeGeographicTransformation, a HVDatumTransformation or a CompositeHVDatumTransformation.
    ClassA builder for creating an EllipticArcSegment whose methods can be called on any thread.
    ClassRepresents an elliptic arc segment for use in a Multipart geometry. To create an elliptic arc segment use the EllipticArcBuilderEx object.
    ClassAn envelope is an axis-aligned box described by the coordinates of the lower left corner and the coordinates of the upper right corner. To create an envelope use the EnvelopeBuilderEx object.
    ClassA builder for creating an Envelope whose methods can be called on any thread.
    ClassOptions for creating a geodesic ellipse with the GeometryEngine.GeodesicEllipse function.
    ClassOptions for creating a geodesic ellipse with the GeometryEngine.GeodesicSector function.
    Class A geographic transformation is used when projecting geometries between two different geographic coordinate systems. A geographic transformation converts everything that needs to be changed including the units, prime meridian, and the ellipsoid. Every transformation is defined in a particular forward direction, say from GCS A to GCS B, but all are reversible. For example, a geographic transformation may be defined to convert from NAD27 to WGS84. If you are projecting from WGS84 to NAD27, you can use the reversed form of the transformation.
    Class Provides the name, well-known ID (WKID), and WKIDs of the spatial references from which and to which the data will be projected.
    Class An abstract base class for objects that define geometric shapes. Geometry objects can be used as geometry definitions for rendering data.
    ClassA class representing a GeometryBag. To create a geometry bag use the GeometryBagBuilderEx object.
    ClassBuilder for creating a GeometryBag.
    Class An abstract base class for geometry builders.
    Class Utility for performing geometric operations.
    Class Represents a grid unit for a geographic location.
    Class A hv (horizontal/vertical) datum transformation is used when projecting Z-Aware geometries between two different geographic coordinate systems and two different vertical coordinate systems. As with geographic transformations, a hv datum transformation converts everything that needs to be changed including the units, prime meridian, and the ellipsoid. In addition, a hv datum transformation transforms height. Every transformation is defined in a particular forward direction, but all are reversible. For example, suppose your Z-Aware geometry is in WGS84 with vertical coordinate system EGM2008_Geoid, and you want to project to NAD83_2011 with vertical coordinate system NAD83_2011. A hv datum transformation is defined to project your Z-Aware geometry from WGS84 with vertical coordinate system EGM2008_Geoid to NAD83_2011 with vertical coordinate system NAD83_2011. If you are projecting from NAD83_2011 with vertical coordinate system NAD83_2011 to WGS84 with vertical coordinate system EGM2008_Geoid to NAD83_2011, you can use the reversed form of the transformation.
