Abstract: Computer software and user's guide for Hardwood Log Defect Photographic Database. The database contains photographs and information on external hardwood log defects and the corresponding internal characteristics. This database allows users to search for specific defect types, sizes, and locations by tree species. For every defect, the database contains photos of the defect at 1-inch intervals as it penetrates the log and a brief summary of the defect's measurements and features. The defect data presented here was collected from three sites in West Virginia.
