Rice Leaf Area Index (LAI) estimates from hyperspectral data

SPIE Proceedings, 2003
In this paper, we report some correlation analysis results between hyperspectral data in the spectral range of approximately 350nm-935nm and LAI of rice. Hyperspectral measurements were taken using an Analytical Spectral Devices (ASD) FieldSpec UV/VNIR Spectroradiometer at the experiment farm in 1999 and 2000.The potential of hyperspectral data for ...

Estimation of leaf area index (LAI) using POLInSAR: Preliminary research

2011 IEEE International Geoscience and Remote Sensing Symposium, 2011
Polarimetric interferometric synthetic aperture radar (POLInSAR) has been used to extract the forest height successfully. Leaf area index (LAI) is an important parameter for the estimation of forest biomass, however presently the most of LAI extraction approaches are based on optical data.

Sensitivity analysis for leaf area index (LAI) estimation from CHRIS/PROBA data

Frontiers of Earth Science, 2014
Sensitivity analyses were conducted for the retrieval of vegetation leaf area index (LAI) from multiangular imageries in this study. Five spectral vegetation indices (VIs) were derived from Compact High Resolution Imaging Spectrometer onboard the Project for On Board Autonomy (CHRIS/PROBA) images, and were related to LAI, acquired from in situ ...

Estimating Urban Leaf Area Index (LAI) of Individual Trees with Hyperspectral Data

Photogrammetric Engineering & Remote Sensing, 2012
This study estimated leaf area index (LAI) of individual urban trees as a function of spectral features derived from airborne hyperspectral data. Candidate features included spectral indexes, principal components, and calibrated reflectance values. Hyperspectral images were acquired over Provo, Utah area, and LAI of 204 deciduous trees was measured in ...
