Class | Description | |
---|---|---|
DefinitionSpatialReferenceInfo | A coordinate system specified by a definition string. | |
IDDefinitionSpatialReferenceInfo | A coordinate system specified by an ID and a definition string. | |
IDSpatialReferenceInfo | Spatial reference (coordinate system) specified by an integer ID. | |
SpatialReference | Contains the properties for a spatial reference for geographic data. | |
SpatialReferenceInfo | Abstract representation of coordinate system properties. | |
UnknownSpatialReferenceInfo | SpatialReferenceInfo for an unknown coordinate system. |
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.
