摘要
A pedagogic problem in forestry and landscape management is to visualize future landscape effects of forest growth and current management activities in the forest. This paper presents a method for forecasting digital image projections of forest landscape dynamics. Static nonlinear regression functions estimate the digital numbers in a Landsat Thematic Mapper image. Regressors used are forest stand variables. By estimating the future forest stand data, based on intermediate treatment and growth future satellite digital images are created. In a case study example, the future landscape of a forest block in the province of Vasternorrland, Sweden, is projected to demonstrate the application of this visualization technique.
