Technical Review of the Vector Product Format Symbol Set Prototype

摘要

Vector Product Format Symbology (VPFS) is a standard structure for theorganization 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 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.
