CHARACTERIZING LAI SPATIAL AND TEMPORAL VARIABILITY USING A WAVELET APPROACH
Leaf Area Index Remote Sensing Variability Wavelet
2015/12/30
Vegetation plays an important role in the exchange of carbon dioxide, water, and energy between the land surface and the atmosphere. LAI, defined as one-half the total green leaf area per unit of grou...
The Method on Generating LAI Production by Fusing BJ-1 Remote Sensing Data and MODIS LAI Product
Vegetation Computer Simulation MODIS Fusion BJ-1 Remote Sensing Priori Knowledge
2015/11/23
LAI (Leaf Area Index) is the more important parameter of vegetation canopy, which can depict their growth course. So LAI inversion from remote sensing observations is the hot study field, especially f...
ESTIMATION OF LAI USING LIDAR REMOTE SENSING IN FOREST
LiDAR Leaf Area Index (LAI) Point density Vegetation Index Photosynthetically Active Radiation
2015/11/10
Light Detection and Ranging (LiDAR) has been used to extract surface information as it can acquire highly accurate object shape characteristics using geo-registered 3D-points. Therefore, LiDAR can be ...

A PRELIMINARY STUDY ON MECHANISM OF LAI INVERSION SATURATION
Leaf area index saturation vegetation index PROSAIL MIMICS
2014/4/25
Many parameters, such as albedo, vegetation index and leaf area index (LAI) inversed from satellite images, often get saturated when the surface vegetation cover reaches a certain high level. In order...
Study of a Method for Extracting LAI Time-Series Patterns for the Estimation of Crop Phenology
leaf area index crop phenology radiative transfer model vegetation index matched-filter method
2010/11/24
The estimation of crop phenology is necessary to grasp the water use of irrigated farmlands. To estimate the crop phenology, time-series patterns of Leaf Area Index (LAI) are considered effective. A m...
