ESRI.ArcGIS.ADF.Web
ESRI.ArcGIS.ADF.Web.SpatialReference Namespace
See Also  Inheritance Hierarchy
ESRI.ArcGIS.ADF.Web.SpatialReference contains classes for working with projections (coordinate systems) of map resources. The SpatialReference class defines the projection of a resource by means of its CoordinateSystem property. This property accepts one of several types in this namespace that extend SpatialReferenceInfo.

Classes

 ClassDescription
ClassDefinitionSpatialReferenceInfo A coordinate system specified by a definition string.
ClassIDDefinitionSpatialReferenceInfo A coordinate system specified by an ID and a definition string.
ClassIDSpatialReferenceInfo Spatial reference (coordinate system) specified by an integer ID.
ClassSpatialReference Contains the properties for a spatial reference for geographic data.
ClassSpatialReferenceInfo Abstract representation of coordinate system properties.
ClassUnknownSpatialReferenceInfo SpatialReferenceInfo for an unknown coordinate system.

Remarks

The projection may be defined several ways, and hence the abstract SpatialReferenceInfo class is extended by several classes in this namespace. Common coordinate systems have been given ID numbers, which are used with IDSpatialReferenceInfo. They may also be defined with a string that describes all characteristics (DefinitionSpatialReferenceInfo). Finally, the projection may be unknown, which is signaled by using UnknownSpatialReferenceInfo.
