Digital Ortho Quad Quadrangle (DOQQ) images have long been a cornerstone of land use and land cover research. More recently DOQQ have widely been used in transportation research. The objective of this research is to explore the potential integration of DOQQ and Geographic Information Systems (GIS) into web-based and interactive geo-visualization (GVIS) for transportation decision-making. The objective will be presented in the context of a proposed Environmental Impact Assessment (EIA) of the Corridor H transportation development project in the Appalachia, West Virginia.

In transportation decision-making, the role of representation of remote sensing data and geo-visualization is becoming more useful. Displaying such spatial data in a manner that is easily understood by the general public and decision-making communities is a cornerstone for better planning. The DOQQ images and Corridor H GIS coverage are integrated into GVIS to produce 2.5D representation, Virtual GIS, and non-threatening graphics to explore the environmental and social impacts of the proposed highway. The current state of the art tends to offer potential in this transportation development project. This poster illustrates (1) the existing 2D CAD map representation 2) 2.5D representation of DOQQ and Corridor H GIS (3) integration of DOQQ into interactive/dynamic GVIS.
