    7.4 Example

Gives principles for describing spatial schemas which can be part of application schemas. These can be used for structuring, defining, updating, encoding, querying, transforming and transferring geographic data. Specifies the constructs for the representation of geometry and topology of geographic objects. These constructs are defined in spatial schemas according to needs from the applications.
