Three Dimensional Visualization Improves Site Conceptual Models
Track: 3D GIS
Authors: Robbi McKinney

A picture states a thousand words. If this is the case, then a model surely speaks one million. A scaled representation and ability to examine a site at mulitple angles in 3-D allows viewers to quickly grasp the spatial data relationships. 3-D site models also allow users and viewers to see patterns and relationships that would normally be obscured in the 2-D map. A dynamic conceptual site model was developed to evaluate contaminant distribution and characterize site conditions at the former CSXT Salamanca railyard located in East Salamanca, New York. ArcScene was used to provide an overall geographic setting, thereby eliminating the need for physical trips to the site. Topography, hydrology, and site features were accurately displayed in 3-D. The tool allows for analysis and visualization by both technical and non-technical audiences. Therefore, all stakeholders are armed with the best information available to understand and interpret site conditions.
