What is it about?
Quick and economical ways of detecting of planimetric and volumetric changes of forest areas are in high demand. A research platform, called FORSAT (A satellite processing platform for high resolution forest assessment), was developed for the extraction of 3D geometric information from VHR (very-high resolution) imagery from satellite optical sensors and automatic change detection.

Why is it important?
We developed a software suite, so called FORSAT which is capable of providing spatial information for long term monitoring of forest areas. The basic input data is VHR satellite imagery. The software consists of mutually linked modules which are pre-processing, geo-referencing, DSM generation and post-processing, and 3D comparison and analysis. The pilot application study demonstrates the capability of the FORSAT software especially for forest change analysis and provides an insight in the various service applications related to forest as well as other topics. The results of FORSAT provide single source, flexible forest information solutions with a very competitive price/quality ratio, allowing for new market entry in the forest sector.
Perspectives
FORSAT is a single source and flexible forest information solution with a very competitive price/quality ratio, allowing expert and non-expert remote sensing users to monitor forests in three and four dimensions from VHR optical imagery for many forest information needs. The capacity and benefits of FORSAT have been tested in six case studies located in Austria, Cyprus, Spain, Switzerland and Turkey, using optical data from different sensors and with the purpose to monitor forest with different geometric characteristics.
