This chapter presents an object-oriented approach for handling Vector Product Format (VPF) mapping databases as produced by the U.S. Defense Mapping Agency. This approach is implemented in the Object Vector Product Format (OVPF) Smalltalk prototype developed by the U.S. Naval Research Laboratory and the University of Florida. OVPF provides an integrated framework for four VPF products: Digital Nautical Chart, World Vector Shoreline Plus, Urban Vector Smart Map, and Vector Smart Map level 0. Having four VPF products and with the update capability, persistent storage of these spatial data was one of the concerns. This chapter will introduce the changes to the data model to accommodate the ObjectStore implementation and migration process of each of the products to the ObjectStore ODBMS.
