Multimedia GIS Development and 3-Dimensional Tour of Powerline Transmission Route, Tuscon, Arizona — Tucscon Electric Power
Due to increased energy demand in southern Arizona, the Department of Energy requested that Tetra Tech prepare an Environmental Impact Statement (EIS) for the proposed alternatives to constructing a 175 mile transmission line.
To support the EIS and better communicate environmental consequences of potential power line routes, Tetra Tech created a multimedia web-based interface for 2-D, 3-D, and animated GIS maps and data. The final product is a component of the website that accompanies the EIS. The purpose of this GIS and 3-dimensional tour website is to provide an engaging and accurate explanation of the environmental consequences of the project’s alternatives for constructing a powerline to the public and decision-makers. Two-dimensional GIS-based maps, data and aerial photography can be viewed through a user-friendly, intuitive interface to allow illustration of various resources (threatened & endangered species, vegetation, population, land use, viewsheds, etc.).
To improve visualization of the power line alternatives, 3-D animated "fly-throughs" of the landscape elements were prepared. These fly-throughs use GIS data, photography, videography, and computer animation to illustrate current site characteristics and simulate future conditions.
