Abstract:
In this paper we present a comprehensive set of advancements to our unique hybrid Geographical Information System (GIS). Although many existing commercial 3D GIS systems offer 2D views they are typically isolated from the 3D view in that they are presented in a separate window. Our system is a novel hybrid 2D/3D approach that seamlessly integrates 2D and 3D views of the same data. In our interface, multiple layers of information are continuously transformed between the 2D and 3D modes under the control of the user, directly over a base-terrain. In this way, our prototype GIS allows the user to view the 2D data in direct relation to the 3D view within the same window. In this work we progress the concept of a hybrid GIS by presenting a set of expanded capabilities within our distinctive system. These additional facilities include: landmark layers, 3D point layers, and chart layers, the grouping of multiple hybrid layers, layer painting, the merging of layer controls and consistent zoo
ming functionality.
