There has been extensive monitoring of forest clearing using remote sensing. The central remaining questions in this context concern the ability to monitor large areas with satellite systems like Landsat, which allow for sufficient spatial detail to identify small patches of deforestation. Applications over large areas require generalisation of change detection procedures across space and time. Another dimension of forest monitoring concerns tracking growth of forest stands over time. The combined use of the spectral and temporal domains can indicate stand age, as modelled using the principles of geometric optics. Changes in stand reflectance through time are highly nonlinear in rate and direction.
