Download or read book Satellite Sensor Calibration Verification Using the Cloud Shadow Method written by National Aeronautics and Space Administration (NASA) and published by Createspace Independent Publishing Platform. This book was released on 2018-08-20 with total page 34 pages. Available in PDF, EPUB and Kindle. Book excerpt: An atmospheric-correction method which uses cloud-shaded pixels together with pixels in a neighboring region of similar optical properties is described. This cloud-shadow method uses the difference between the total radiance values observed at the sensor for these two regions, thus removing the nearly identical atmospheric radiance contributions to the two signals (e.g. path radiance and Fresnel-reflected skylight). What remains is largely due to solar photons backscattered from beneath the sea to dominate the residual signal. Normalization by the direct solar irradiance reaching the sea surface and correction for some second-order effects provides the remote-sensing reflectance of the ocean at the location of the neighbor region, providing a known 'ground target' spectrum for use in testing the calibration of the sensor. A similar approach may be useful for land targets if horizontal homogeneity of scene reflectance exists about the shadow. Monte Carlo calculations have been used to correct for adjacency effects and to estimate the differences in the skylight reaching the shadowed and neighbor pixels. Reinersman, P. and Carder, K.

Download or read book Hyperspectral Satellites and System Design written by Shen-En Qian and published by CRC Press. This book was released on 2020-04-02 with total page 627 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hyperspectral Satellites and System Design is the first book on this subject. It provides a systematic analysis and detailed design of the entire development process of hyperspectral satellites. Derived from the author’s 25-year firsthand experience as a technical lead of space missions at the Canadian Space Agency, the book offers engineers, scientists, and decision-makers detailed knowledge and guidelines on hyperspectral satellite system design, trade-offs, performance modeling and simulation, optimization from component to system level, subsystem design, and implementation strategies. This information will help reduce the risk, shorten the development period, and lower the cost of hyperspectral satellite missions. This book is a must-have reference for professionals in developing hyperspectral satellites and data applications. It is also an excellent introductory book for early practitioners and students who want to learn more about hyperspectral satellites and their applications.

Download or read book Fluvial Remote Sensing for Science and Management written by Patrice Carbonneau and published by John Wiley & Sons. This book was released on 2012-08-15 with total page 603 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book offers a comprehensive overview of progress in the general area of fluvial remote sensing with a specific focus on its potential contribution to river management. The book highlights a range of challenging issues by considering a range of spatial and temporal scales with perspectives from a variety of disciplines. The book starts with an overview of the technical progress leading to new management applications for a range of field contexts and spatial scales. Topics include colour imagery, multi-spectral and hyper-spectral imagery, video, photogrammetry and LiDAR. The book then discusses management applications such as targeted, network scale, planning, land-use change modelling at catchment scales, characterisation of channel reaches (riparian vegetation, geomorphic features) in both spatial and temporal dimensions, fish habitat assessment, flow measurement, monitoring river restoration and maintenance and, the appraisal of human perceptions of riverscapes. Key Features: • A specific focus on management applications in a period of increasing demands on managers to characterize river features and their evolution at different spatial scales • An integration across all scales of imagery with a clear discussion of both ground based and airborne images • Includes a wide-range of environmental problems • Coverage of cutting-edge technology • Contributions from leading researchers in the field

Download or read book Investigation of Panchromatic Satellite Imagery Sensor Low Bias in Shadow Method Aerosol Optical Depth Retrieval written by Brian J. Rivenbark and published by . This book was released on 2009 with total page 61 pages. Available in PDF, EPUB and Kindle. Book excerpt: A technique known as the Shadow Method was developed for calculating aerosol optical depths by measuring the radiance difference between shaded and unshaded regions in high-resolution satellite imagery by Vincent (2006). Previous research investigated use of the Shadow Method in regions of dust obscuration using buildings and clouds as shadow generation sources and a variety of background surfaces. A recurring low bias was seen when using the Shadow Method with the QuickBird satellite's panchromatic sensor. QuickBird and WorldView1 commercial imagery was examined using the Shadow Method at several sites co-located with AERONET observations sites. The results show that low bias is not attributed to sensor calibration, processing methods of the imagery, or water vapor content. The most likely source of low bias is the region of interest (ROI) selection geometry within the shadow regions.
