Application of GIS in the Inventory of Environmentally Sensitive Resources Within a State Transportation Corridor Author: Robert Kirkman 707 SW Washington St. Phone: 503-224-3445 Transportation planning and maintenance activities frequently must address sensitive environmental resources. With increasing concerns for sensitive habitats and an ever-growing number of environmental regulations, the Oregon Department of Transportation required a system to report and catalog these areas to keep them from inadvertent harm. Additionally, such an inventory would assist in early environmental scoping. Previous, more traditional attempts demonstrated the need to develop a more timely and cost-effective means. This project utilizes a combination of GIS, GPS, and digital orthophotography to provide a comprehensive inventory that is tied to a State-wide linear referencing system (LRS). Furthermore, the application of these technologies allowed the generation of a more comprehensive and precise product in less time than traditional inventory methods. |
