Abstract
Analysis of Complex Data Using 3D GIS Track: Modeling Author(s): Gary Hecox Three-dimensional GIS methods for display and analysis of multiple and complex datasets have been developed. These techniques demonstrably improve the presentation and understanding of site conditions to allow engineers, scientists, and the public to better understand site geography, groundwater, geology, and other environmental issues. The primary advantage of these new techniques over traditional methods is that multiple datasets with different features can now readily be integrated and visualized, quantitatively evaluated, and presented together while original data integrity is maintained. These techniques are illustrated by three case studies: a landfill where the site geology, local groundwater system, landfill operations, and key surface water features were included in a 3D GIS virtual model; a demonstration of improved data understanding using GIS multivariate data display methods; and an illustration of 3D GIS methods in the development of a groundwater flow and transport models.
