FORSAT: a 3D forest monitoring system for cover mapping and volumetric 3D change detection
Efstratios Stylianidis,Devrim Akca,Daniela Poli,Martin Hofer,Armin Gruen,Victor Sanchez Martin,K. Smagas,Andreas Walli,Orhan Altan,Elisa Jimeno,Alejandro Garcia +10 more
TL;DR: ForSAT is a single source and flexible forest information solution, allowing expert and non-expert remote sensing users to monitor forests in three and four dimensions, and has been tested and validated in case studies located in Austria, Switzerland and Spain.
Book ChapterDOI
Pre- and Post-Fire Comparison of Forest Areas in 3D
Devrim Akca,Efstratios Stylianidis,Daniela Poli,Armin Gruen,Orhan Altan,Martin Hofer,K. Smagas,Victor M. Sanchez,Andreas Walli,Elisa Jimeno,Alejandro Garcia +10 more
TL;DR: The test studies showed that FORSAT is an operational software capable of providing spatial (3D) and temporal (4D) information for monitoring of forest fire areas and sustainable forest management.
Journal ArticleDOI
Volumetric forest change detection through vhr satellite imagery
Devrim Akca,Efstratios Stylianidis,K. Smagas,Martin Hofer,Daniela Poli,Armin Gruen,Victor Sanchez Martin,Orhan Altan,Andreas Walli,Elisa Jimeno,Alejandro Garcia +10 more
TL;DR: For instance, the FORSAT (A satellite processing platform for high resolution forest assessment) as discussed by the authors was developed for the extraction of 3D geometric information from VHR (very high resolution) imagery from satellite optical sensors and automatic change detection.
Journal ArticleDOI
3-dimensional pre- and post-fire comparison of forest areas
Devrim Akca,Efstratios Stylianidis,Daniela Poli,Armin Gruen,Martin Hofer,K. Smagas,Victor M. Sanchez,Andreas Walli,Elisa Jimeno,Alejandro Garcia +9 more
TL;DR: FORSAT is a single source and flexible forest information solution, 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.
Proceedings ArticleDOI
A Precision Estimation Method for Volumetric Changes
Devrim Akca,Armin Gruen,K. Smagas,Elisa Jimeno,Efstratios Stylianidis,Orhan Altan,Victor Sanchez Martin,Alejandro Garcia,Daniela Poli,Martin Hofer,Andreas Walli +10 more
TL;DR: In this paper, the authors present an operational DEM generation, co-registration and DoD comparison software in which the surface changes are quantified in metric units of volume, and a practical method based on the law of error propagation is developed to estimate the theoretical precisions of volumetric changes.
