The forest attributes of interest were percent vegetation cover, percent conifer cover, conifer age, and conifer size. Online Linkage: http://www.fsl.orst.edu/larse/wov/88wov.html Description Abstract: This data layer provides a composite map of forest cover for the study area. Purpose: To provide cost-effective, flexible, and seamless map products for use in regional scale ecological assessments. Supplemental_Information: Procedures_Used: Unsupervised classification, regression analysis, and applied radiometric normalization.
