A method based on radiative transfer models (RTM) incorporating multi-angle data is used to estimate LAI. The estimation of LAI from inversion will be based on Look Up Tables (LUT) approach. The usefulness of the method was verified using the data of Spectral database of Chinese typical features. The determination coefficient R2 between estimated result and measurement data is high to 0.6046. The...
Satellites sensors, e.g., MODIS, NOAA-AVHRR, SEAWIFS, are widely used satellite data. However, the coarse spatial resolution of these data limited the application. In this paper, we propose a novel approach for the simulation of high spatial resolution image from mutil-temporal coarser resolution satellite data that will has both high spatial resolution and temporal resolution. Through detecting temporal...
This paper used water related vegetation indices calculated from Hyperion image to make water content mapping. The study area is located in Zhangye city, Gansu province in Heihe River Basin of China. Hyperion hyperspectral data was acquired on September 10, 2007. Using Hyperion reflectance of 35 plots, the relationships between vegetation indices and Equivalent Water Thickness (EWT) were calculated...
In this paper, we focus on the area covered by vegetation and compare the canopy reflectance derived from MODIS images with reflectance simulated by radiation transfer model. Instead of statistic models, physical models are chosen because of the explicit physical foundation that they possess. Two sampling areas are collected in Jiangxi province in China. Detailed information of vegetation in these...
This paper evaluated the capability of FLAASH in ENVI software to make atmospheric correction for Hyperion hyperspectral image and ALI image. Hyperion and ALI sensors are two of the three instruments onboard NASA EO-1 satellite, New Millennium Program (NMP) launched on November 21, 2000, and Hyperion is the first spaceborne hyperspectral imaging spectrometer. The study area is Zhangye city (37deg28'N-39deg57'N,...
