Scope

This standard defines the concept of describing the temporal characteristics of geographic information. This standard is based on the existing information technology standards for temporal information exchange, and provides the basis for defining temporal element attributes, element operations, element associations, and metadata for defining temporal characteristics of geographic information. This standard mainly considers the temporal characteristics of geographic information abstracted from the real world, and it emphasizes effective time rather than transaction processing time.
