Remote Sensing Monitoring of the Dynamic Changes of Vegetation Coverage and Its Types before and after the Emergent Water Transportation to the Lower Reaches of the Tarim River
Two factors of the vegetation coverage and its types sensible to the ecological changes before and after the Emergent Water Transportation Project are investigated based on three periods of the multi-source and multi-type remote sensing (RS) images such as TM image, ETM image and ASTER image collected from the summer of 1999, 2002 and 2004, respectively, together with the basic geographic data ...
متن کاملEvaluation of oasis stability in the lower reaches of the Tarim River
Oasis stability in the lower reaches of the Tarim River was assessed at the landscape scale (including changes in landscape pattern and land use in the oasis) and at the regional scale (including the cold-island effect and NDVI of the oasis) based on the methods of landscape ecology, GIS and Remote Sensing (RS). Thematic Mapping (TM) remote sensing images from 1990, 2000 and 2009 were employed ...
متن کاملRemote sensing of vegetation based on canopy spectral invariants
The concept of canopy spectral invariants states that simple algebraic combinations of leaf and canopy spectral transmittance and reflectance become wavelength independent and determine a small set of canopy structure specific variables. This set of structural variables specify the spectral response of a vegetation canopy to the incident solar radiation and allow for a simple and accurate param...
متن کاملRemote Sensing Analysis on Dynamic Changes of the Soil Salinization in the Upper Stream of the Tarim River
This research attempts to collect and interpret the soil salinization in the upper stream of the Tarim River on the basis of the multisource and multi-type remote sensing images and basis background data in the springs of 1999, 2002 and 2004 respectively, applying the information technologies of remote sensing (RS), global positioning system (GPS), geographic information system (GIS), and massi...
متن کاملSpectrally based remote sensing of river bathymetry
This paper evaluates the potential for remote mapping of river bathymetry by (1) examining the theoretical basis of a simple, ratio-based technique for retrieving depth information from passive optical image data; (2) performing radiative transfer simulations to quantify the effects of suspended sediment concentration, bottom reflectance, and water surface state; (3) assessing the accuracy of s...
