Sensitivity Analysis of Spectral Indices to Ozone Absorption Using Physical Simulations in a Forest Environment: Comparative Study between MODIS, SPOT VÉGÉTATION & AVHRR
نویسنده
چکیده
Considering a forest cover (Balsam Fir with various densities) we analyze the sensitivity of several vegetation indices to ozone absorption using physical simulations in the spectral bands of MODIS, VEGETATION and AVHRR sensors. Except for the EVI, MSR and GARI, the results indicate that all the vegetation indices used in this study normalize the ozone absorption in particular TSARVI and GEMI. In addition, this study underlines the MODIS sensor contribution to minimize the ozone absorption effect.

SPOT-5 Spectral and Textural Data Fusion for Forest Mean Age and Height Estimation
Precise estimation of the forest structural parameters supports decision makers for sustainable management of the forests. Moreover, timber volume estimation and consequently the economic value of a forest can be derived based on the structural parameter quantization. Mean age and height of the trees are two important parameters for estimating the productivity of the plantations. This research ...
متن کاملBurned land mapping using NOAA-AVHRR and TERRA-MODIS
Spatial and temporal analysis of MODIS and AVHRR images have been carried out to discriminate burned areas from other land covers. Spatial and temporal analysis were performed based on statistical separability and temporal changes. The objective of these analysis was to find out the most sensitive bands for burned land mapping in order to design spectral indices better adapted to the discrimina...

We give a comprehensive assessment of the hi...
متن کاملRemote Sensing Based Retrieval of Snow Cover Properties Case Study (Shirkooh Mountain Yazd, Iran)
Snow cover area is one of the most important criteria to calculate snow melt runoff. This can have an effect on the biology of the plant and the environment of a region. Using the catchment basin physical characteristic to calculate snow cover area is a conventional method, though its accuracy is not good enough. Most of the useful methods in calculating snow cover area are based on satellite i...
