Detection of optical water quality parameters for eutrophic waters by high resolution remote sensing

TL;DR: The PC:Chl-a distribution generated using HSI proved to be negatively dependent on flow velocity and successfully indicated cyanobacteria risk regions in the study area and the MODTRAN 6 correction led to the highest R2 values and lowest root mean square error values for all algorithms in terms of PC and Chl- a.

TL;DR: In this paper, the authors measured the absorption spectra (250-800 nm) of yellow substance along five onshore-offshore transects in the Southern Bight of the North Sea in different seasons.

TL;DR: The theoretical framework for a four-band semi-analytical algorithm (FBA_PC) which isolates PC absorption from second-order variability caused by yellow matter and other phytoplankton pigment absorption is provided.

TL;DR: Results support future applicability of this algorithm to derive the water-leaving radiance and new indices from the OSAB pixels for qualitative and quantitative assessment of the optical and biological OSABs properties as well as their associated ecological activities.

TL;DR: In this article, the authors present a textbook for introductory courses in remote sensing, which includes concepts and foundations of remote sensing; elements of photographic systems; introduction to airphoto interpretation; air photo interpretation for terrain evaluation; photogrammetry; radiometric characteristics of aerial photographs; aerial thermography; multispectral scanning and spectral pattern recognition; microwave sensing; and remote sensing from space.

TL;DR: In this article, the concept of remote sensing elements of photogrammetry was introduced. Butterfly, thermal, and hyperspectral sensors were used to interpret multispectral, thermal and hypererspectral images.

TL;DR: Monte Carlo simulations of the transfer of radiation in the ocean are used to compute the apparent optical properties of a flat homogeneous ocean as a function of the inherent optical properties and it is shown that these relations can be used with measurements of the upwelling and downwelling irradiance, the beam attenuation coefficient, and the incident radiance distribution.

TL;DR: In this article, a simple spectral atmospheric radiative transfer model for oceanographic applications is proposed, which is based on spectral extraterrestrial solar u-radiance corrected for earth-sun orbital distance.
