Foreward to the Special Issue on Multi-Scale Forestry Applications Supported by Remote Sensing and Spatial Information Systems

The papers in this special issue represent the state of the art on forest modeling and mapping techniques to provide up-to-date, consistent information on forests at different scales, ranging from local, regional through to transnational and global scales. The papers can be broadly categorized in two categories: those dealing with passive, optical remote sensing applications with a particular focus on tropical forest cover and biomass mapping, and those describing applications of active remote sensing using either radar or LiDAR applications.
