Spectrally 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...
متن کاملRemote Sensing-Derived Bathymetry of Lake Poopó
Located within the Altiplano at 3,686 m above sea level, Lake Poopó is remarkably shallow and very sensitive to hydrologic recharge. Progressive drying has been observed in the entire Titicaca-Poopó-Desaguadero-Salar de Coipasa (TPDS) system during the last decade, causing dramatic changes to Lake Poopó’s surface and its regional water supplies. Our research aims to improve understanding of Lak...
متن کاملDeriving Bathymetry from Multispectral Remote Sensing Data
The use of passive satellite sensor data in shallow waters is complicated by the combined atmospheric, water, and bottom signals. Accurate determination of water depth is important for monitoring underwater topography and detection of moved sediments and in support of navigation. A Worldview 2 (WV2) image was used to develop high-resolution bathymetric maps (four meters) that were validated usi...
متن کاملBathymetry from active and passive airborne remote sensing – looking back and ahead
Introduction Knowledge about the bathymetry of water bodies is of high economic, social, and ecologic importance. Whereas charting bathymetry for navigational purposes is indispensable for ensuring safe shipping traffic, monitoring the quantity and quality of fresh water resources gains more and more importance, especially in the light of climate change. In the European context three water rela...
متن کاملPolarimetric Passive Remote Sensing
We seek to understand and predict the evolution of the brightness temperature (four Stokes parameters) of wind driven foam-covered ocean surfaces. The correlation of polarimetric variation is studied as function of the medium state, modeled as a rough surface (ocean) overlayed by a random medium (foam). Many independent results are obtain by using a wide variety of electromagnetic techniques, ...
