Using Geographic Information, Multimedia and Landscape Modeling as Integrated Visualization Tools in Developing Highway Corridor Management Plans Christopher J. SEEGER 1 Introduction One of the difficulties when working with corridor projects is that they tend to cover great distances and can include thousands of resources and features that need to be accounted for in the corridor plan. Documenting a corridor often requires that a large expenditure of time and project funds be spent on numerous trips into the field to collect and verify data. Safety is also an issue with transportation corridor projects due to the lack of safe roadside parking, especially along Interstate corridors. One solution that encourages safety while reducing the need to traverse the corridor is to utilize digital audio, video, photography and other multimedia tools to capture information about the corridor for review back in the project studio. When integrated with geographic data, this multimedia information can be a very beneficial resource both during and after the planning and design process. This paper will present the technique used to build a custom designed integrated geographic, multimedia, and visualization system as part of the Iowa State University, Department of Landscape Architecture project – Maintaining The Image Of Iowa Beyond The Right-Of-Way: A Corridor Management Plan For Significant Natural, Cultural And Visual Adjacencies To Interstate-80. 1.1 Project Background This Iowa Department of Transportation funded project involved developing a management plan for the Iowa portion of the Interstate 80 corridor. This corridor management plan documents the cultural, historic, and agrarian features that contribute to the internationally recognized nostalgic “Image of Iowa.” Additionally, the plan identifies methods for the preservation of these features while encouraging economic growth, environmental conservation, and transportation safety. The 330 road miles and approximately 2,000 square miles of land (3 mile buffer either side of the roadway) that make up the corridor as well as the number of resources mapped (4,000 farms, 62 municipal entities and 17 county zoning jurisdictions) necessitated the need for a Geographic Information System (GIS). ArcView GIS was used to both organize the thematic data and to model various spatial relationships between the corridor features. The hyperlink functions within ArcView provided an efficient method to connect GPS located digital photographs of corridor resources with their geographic attributes. Using the hyperlink function, various types of media including text documents, digital photos, and simple video files could be hot linked
