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).
