The Harvest Unit and Access Delineation Project (HUAD) was completed this year to develop a Logging and Transportation Plan for 633,000 acres of Oregon State Forests. The Oregon Department of Forestry (ODF) is developing a spatial model, known as the Harvest and Habitat Model, to simulate timber yields and wildlife habitat from the State Forests over the next 150 years. The logging and transportation coverages developed through the HUAD project are two of the 24 spatial data sets required for the Harvest and Habitat Model.With the new harvest and road data now completed, this paper describes the process and challenges to building the new HUAD data layers and their application in the Forest model. Using multi platforms, we built integrated polygon, node and line topology with robust attribute tables and transportation analysis.
16,000 polygons, 24,000 nodes, 25,000 arcs, and 700 maps later, this is our story.
