Abstract
  • The U.S. Forest Service has been actively using new information technologies since the formation of the agency. Currently forests are using Geographic Information Systems (GIS) for mapping, data storage, modeling, and spatial analysis. The Siuslaw National Forest has an active GIS with many data layers. A project to correct the errors in the roads layer began in 1996 and involved linking the Transportation Management System Oracle database to the Arclnfo GIS roads layer using a dynamic segmentation process. The updated roads layer is more accurate and has more variables for mapping and analysis. As the Siuslaw has changed from a timber management forest to an ecosystem management forest following the implementation of the President's Northwest Forest Plan, the roads layer has been used for watershed analysis, restoration projects, and for other management purposes. The impacts of roads on forest ecosystems has been widely studied, and restoration activities on the Siuslaw are proving to be successful. The results of these activities and other forest characteristics are stored in the GIS.
