  This paper introduces an extension of descriptive intersection and provides a
framework for descriptive unions of nonempty sets. Fibre bundles provide
structures that characterize spatially near as well as descriptively near sets,
their descriptive intersection and their unions. The properties of four
different forms of descriptive unions are given. A main result given in this
paper is the equivalence between ordinary set intersection and a descriptive
union. Applications of descriptive unions are given with respect to Jeffs-Novik
convex unions and descriptive unions in digital images.
