Abstract

Three-dimensional GIS applications are becoming more popular and more widely used for a variety of analyses. The purpose of this study was to have subjects compare a 2D environment with a 3D environment through a series of tests to determine if the 3D application would more greatly benefit critical infrastructure analysis. Government agencies are responsible for the protection of critical infrastructure and its related impacts. It is necessary to have a system to visualize such information and efficiently identify characteristics and relationships of assets within. Two GIS environments of the same study area and with the same data were created; one used the traditional 2D techniques and the other utilized the 3D techniques. After viewing the environments, subjects were asked questions related to qualitative criteria, quantitative criteria, and open-ended responses. The responses showed favorable results in several of the categories.
