Abstract : Vector Product Format Symbology (VPFS) is a standard structure for the organization of digital symbology to be used with Vector Product Format (VPF) products. The symbols it contains are designed to be compatible with a wide variety of applications which use VPF. VPFS supports a greatly enriched symbology by incorporating logical conditions that allow the association of symbology with feature attribute values. VPFS encompasses most, if not all, of the VPF products providing a standard and consistent symbolization of features across VPF product lines. As the use of multiple VPF products becomes common, this standard symbology set will greatly ease the conflicts between graphical representations of features in different databases. This review examines the appropriateness of the VPFS standard and specification in concept as well as the efficacy of VPFS as implemented in the prototype. It also presents suggestions for the improvement of the VPFS product design.
