ANTARCTIC ICE SHEET SURFACE MASS BALANCE ESTIMATES FROM 2003 TO 2015 USING ICESAT AND CRYOSAT-2 DATA
Antarctica Mass Balance ICESat CryoSat-2
2016/11/30
An assessment of Antarctic ice sheet surface mass balance from 2003 to 2015 has been carried out using a combination of ICESat data from 2003 to 2009 and CryoSat-2 data from 2010 to 2015. Both data se...
CROP AREA ESTIMATES WITH RADARSAT FEASIBILITY STUDY IN THE TOSCANA REGION-ITALY
SAR Crop Mapping Data Integration Rule Base Classification Forward Chaining
2015/12/22
Crop area estimates are crucial for the Common Agricultural Policy of the European Union to manage future intervention on stocks and export policies. The requirement is for early and accurate informat...
MULTI-PLATFORM SATELLITE BASED ESTIMATES OF RUNOFF IN UNGAUGED AREAS
Ungauged area Long-term runoff Multi-platform satellite
2015/11/3
Over the past decades, extreme weather events such as floods and droughts have been on a steady increase. Especially, ungauged or hard-to-reach areas turn out to be the most affected areas by the unex...
SEMANTIC INTERPRETATION OF INSAR ESTIMATES USING OPTICAL IMAGES WITH APPLICATION TO URBAN INFRASTRUCTURE MONITORING
optical InSAR fusion semantic classification InSAR SAR railway monitoring bridge monitoring
2015/9/21
Synthetic aperture radar interferometry (InSAR) has been an established method for long term large area monitoring. Since the launch of meter-resolution spaceborne SAR sensors, the InSAR community has...
SEASONAL COMPARISON OF CARBON FLUX ESTIMATES FROM C-TESSEL MODEL AND MODERATE RESOLUTION IMAGING SPECTRORADIOMETER (MODIS) OVER SEVERAL BIOMES
vegetation the atmosphere
2015/9/8
Carbon dioxide exchange between vegetation and the atmosphere is determined by absorption
of solar radiation by plant leaves and by turbulent transfer in the surface layer. This led to two
different...
LEAF AREA INDEX ESTIMATES OBTAINED FOR MIXED FOREST USING HEMISPHERICAL PHOTOGRAPHY AND HYMAP DATA
Hemisfer Camera Exposure Hyperspectral Data
2015/9/8
The Leaf Area Index (LAI) is an important measure in many ecological applications because vegetation-atmosphere processes of the
canopy, such as photosynthesis are controlled by the foliage and play ...
INFLUENCE OF LOCAL INCIDENCE ANGLE EFFECTS ON GROUND COVER ESTIMATES
Linear Spectral Unmixing MESMA Terrain Effects
2015/9/8
An often neglected source of uncertainty on estimated cover percentage is caused by local view angle effects, where parts of bare soil
patches are not visible due to vegetation blocking the sensor li...
ASSIMILATING REFLECTANCE DATA INTO A ECOSYSTEM MODEL TO IMPROVE ESTIMATES OF TERRESTRIAL CARBON FLUX
Ensemble Kalman filter MODIS GORT
2015/9/8
Ecosystem models are valuable tools for understanding the growth of vegetation, its response to climatic change and its role in the
cycling of greenhouse gasses. Data Assimilation (DA) of synoptic co...
Cereal crops are very important plants just like any other country on the world supplying human food. It is important to know how
much areas these crops cover for agricultural management and policy f...
