VGE, it stands for Virtual geographic environment. VGE’s are a type of 3D modeling or workspace for the experiments run through computer generated geographic analysis systems. By contributing supporting data like geo-visualization, geo-simulation, geo-collaboration, and human participation, all allowing an open virtual environment that correspond to the real world for the assistance of computer-aided geographic experiments that involve both the physical and human realms.  These experiments called CAGE’s standing for Computer-aided geographic experiments have specific frameworks that pertain to how the program runs.
This framework follows four sub-environments: (1) the data environment, (2) the modeling and simulation environment, (3) the interactive environment, and (4) the collaborative environment. All four pieces are discussed according to their different functions, pertinent issues, and corresponding solutions.

  1. How are VGE's used, and for what purpose? Is it a recreation of a "real" environment in a virtual setting for analysis?


    1. VGE's utilize real world data to create a virtual environment that is used in case studies to aid computer based experiments. Examples would be a case study on the simulation of air pollution and its analysis at different geographic scales.
