1. BioSAR 2010 – A SAR campaign in support to the BIOMASS mission Lars Ulander, Anders Gustavsson Swedish Defence Research Agency (FOI), Sweden Pascale Dubois-Fernandez, Xavier Dupuis Office National d’Études et de Recherches Aérospatiales (ONERA), France Johan Fransson, Johan Holmgren, Jörgen Wallerman Swedish University of Agricultural Sciences (SLU), Sweden Leif Eriksson, Gustaf Sandberg, Maciej Soja Chalmers University of Technology, Göteborg, Sweden

4. Test Site at Remningstorp Estate, Sweden Stand-level biomass: 0-370 tons/ha Ground topography: 110–150 m asl 1200 hectars divided into over 300 stands Test site location

5. Remningstorp: Tree species Photos of Norway spruce, Scots pine and birch stands

7. SAR flights by ONERA on 23 September Two calibration trihedrals P + L, full polarimetry SETHI SAR system

8. Geocoded SAR images (3 headings) R=HH, G=HV, B=VV Geometric error < 2m

9. Helicopter lidar data collection Lidar data in 2007 covered only central part Lidar data in 2010 covered the full extent of the test site

10. Lidar DSM 0.5 raster cell size

13. Initial SAR imagery comparison HH = red HV = green VV = blue Images geocoded to UTM 33 N SETHI has higher (2x) bandwidth E-SAR 2007 SETHI 2010

14. Initial SAR imagery comparison HH = red HV = green VV = blue Clear-cutting easily delineated (red circles) Thinning and growth result in subtle changes E-SAR 2007 SETHI 2010

15. First analysis of mapping changes Color-coded change images 2007 vs 2010 Red: Lower value in 2010 Cyan: Higher value in 2010 Gray: Unchanged value Lidar: Biomass SAR: PHV-pol PHH-pol PVV-pol thinning clear cut
