Definition: Extent of the spatiotemporal domain of the coverage.

Description: SOURCE [ISO 19123:2005].NOTE 1 The data type EX_Extent, is defined in ISO 19103. Extents may be specified in both space and time. NOTE 2 The domain extent shall be specified at least in space by using EX_BoundingPolygon, EX_GeographicBoundingBox or EX_GeographicDescription.
