Abstract

A new concept SilvaSat, is proposed to support sustainable use of forest resources at global scope. The key element of the concept is acquisition of accurate satellite images of 0.5 meter ground resolution using a statistical sampling principle. Such images make it possible to collect reliable statistical information on forests at any global location for areas of 20 000 km2 and larger. A global forest inventory and monitoring system can be created by combining the accurate images with field data and coarser resolution satellite data that cover the whole area of interest. With the help of the new system the accuracy of global forest information can greatly be improved. This paper summarizes results of several studies, in which the concept has been developed and evaluated. The concept can be implemented by launching a specific satellite for the acquisition of the accurate images or by ensuring decadal-term image supply from existing commercial and national satellites. The present estimate on the costs of a new satellite ranges from US$ 70 to 160 million (€50-100 million).
