Estimation of leaf area index using an angular vegetation index based on in situ measurements and CHRIS/PROBA data
Multi-angular data LAI vegetation index Remote sensing
2016/11/23
The Normalized Difference Vegetation Index (NDVI) is widely used for Leaf Area Index (LAI) estimation. It is well documented that the NDVI is extremely subject to the saturation problem when LAI reach...

Biochemistry Retrieval Subset Selection Algorithm Multiangular
2015/9/8
Sun and sensor geometry cause directional effects in remotely sensed reflectance data which can influence the estimation of
biophysical and biochemical variables. Previous studies have indicated that...
ANGULAR UNMIXING OF PHOTOSYNTHETIC AND NON-PHOTOSYNTHETIC VEGETATION WITHIN A CONIFEROUS FOREST USING CHRIS-PROBA
Non-Photosynthetic Vegetation spectral unmixing FLIGHT
2015/9/8
Estimating forest variables, such as photosynthetic light use efficiency, from satellite reflectance data requires understanding the
contribution of photosynthetic vegetation (PV) and nonphotosynthet...
RADIATIVE TRANSFER MODEL INVERSION BASED ON MULTI-TEMPORAL CHRIS/PROBA DATA FOR LAI ESTIMATION
Leaf area index Radiative transfer Dynamic canopy model
2015/9/8
Leaf area index (LAI) is a key variable for the understanding and modelling of several eco-physiological processes within a
vegetation canopy. The LAI could thus provide vital information for the man...

PROBA small satellite Hyper Spectral Imaging
2015/9/2
PROBA-1 (Project for On Board Autonomy) is a technology demonstration mission of the European Space
Agency’s General Support Technology Programme. It was launched in October, 2001 into a LEO Sunsynch...
Directional sensitivity analysis of vegetation indices from multi-angular chris/proba data
Vegetation indices CHRIS/PROBA multiangular
2015/8/20
View angle effects present in vegetation indices are either being seen as unwanted information or as an additional source of
information. However, the magnitude of these angular effects remains for m...
