This book was released on 2019 with total page 67 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study explores the applicability of Support Vector Machine (SVM) classifier for extracting open water surface pixels in humid environment with wetlands and urban areas as background noise. The study compares SVM with more commonly used water index, modified Normalized Difference Water Index (mNDWI) for water extraction. The St. Croix watershed area located in Minnesota and Wisconsin provides an ideal test site because of its large number of glaciated lakes and wetlands with varying amount of vegetation and large number of built-up areas. The study uses Landsat Thematic Mapper (TM) data to generate binary images maps showing water and non-water areas in St. Croix watershed area. For validity assessment, reference points from Collect Earth were used. The accuracy of mNDWI and SVM classifiers were tested and compared using error matrices, Kappa coefficient, overall accuracy and McNemar chi-square test. The results show mNDWI performed slightly better than SVM in terms of overall accuracy and kappa coefficient. More specifically, the visual inspection shows that mNDWI accurately extracted water from narrow streams and wide rivers while SVM extracted water more accurately from locations in close proximity to urban areas such as reservoirs, boat launching ramps and locations with preponderance of wetlands.

This book was released on 2015 with total page 70 pages. Available in PDF, EPUB and Kindle. Book excerpt: Monitoring lake quality remotely offers an economically feasible approach as opposed to in-situ field data collection. Researchers have demonstrated that lake clarity can be successfully monitored through the analysis of remote sensing. Evaluating satellite imagery, as a means of water quality detection, offers a practical way to assess lake clarity across large areas, enabling researchers to conduct comparisons on a large spatial scale. Landsat data offers free access to frequent and recurring satellite images. This allows researchers the ability to make temporal comparisons regarding lake water quality. Lake water quality is related to turbidity which is associated with clarity. Lake clarity is a strong indicator of lake health and overall water quality. The possibility of detecting and monitoring lake clarity using Landsat8 mean brightness values is discussed in this report. Lake clarity is analyzed in three different reservoirs for this study; Brookeville, Geist, and Eagle Creek. In-situ measurements obtained from Brookeville Reservoir were used to calibrate reflectance from Landsat 8's Operational Land Imager (OLI) satellite. Results indicated a correlation between turbidity and brightness values, which are highly correlated in algal dominated lakes.

Download or read book Wetlands Detection Methods Investigation written by K. H. Lee and published by . This book was released on 1991 with total page 84 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this investigation was to research and document the application of remote sensing technology to wetland detection and mapping. Various remote sensing sensors and platforms are evaluated (1) for suitability to monitor specific wetlands systems; (2) for their effectiveness in detailing the extent of wetlands; (3) for their capability to monitor changes; and (4) for the resulting relative cost-benefits of implementing and updating wetlands databases. The environment to be monitored consists of physiographic and ecological wetland resources affected directly or indirectly by anthropogenic activity. Air craft and satellite remote sensing can be used to record and assess the condition of these resources. Monitoring of environmental conditions is based on the observation and interpretation of certain landscape features. Although some forms of monitoring are continuous, resource monitoring from aircraft and satellite platforms is periodic in nature, with change being documented through a series of observations over a given span of time. This report summarizes the findings of a bibliographic search on the methods used to inventory and/or detect changes in wetland environments. The bibliography contains numerous citations and is not intended to be all-inclusive. Books, major journals, and symposium proceedings were examined. The findings documented will provide the potential user with a basic understanding of remote sensing technology as it is applied to wetland monitoring and trend analysis.

Download or read book Bio optical Modeling and Remote Sensing of Inland Waters written by Deepak R. Mishra and published by Elsevier. This book was released on 2017-04-28 with total page 334 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bio-optical Modeling and Remote Sensing of Inland Waters presents the latest developments, state-of-the-art, and future perspectives of bio-optical modeling for each optically active component of inland waters, providing a broad range of applications of water quality monitoring using remote sensing. Rather than discussing optical radiometry theories, the authors explore the applications of these theories to inland aquatic environments. The book not only covers applications, but also discusses new possibilities, making the bio-optical theories operational, a concept that is of great interest to both government and private sector organizations. In addition, it addresses not only the physical theory that makes bio-optical modeling possible, but also the implementation and applications of bio-optical modeling in inland waters. Early chapters introduce the concepts of bio-optical modeling and the classification of bio-optical models and satellite capabilities both in existence and in development. Later chapters target specific optically active components (OACs) for inland waters and present the current status and future direction of bio-optical modeling for the OACs. Concluding sections provide an overview of a governance strategy for global monitoring of inland waters based on earth observation and bio-optical modeling. Presents comprehensive chapters that each target a different optically active component of inland waters Contains contributions from respected and active professionals in the field Presents applications of bio-optical modeling theories that are applicable to researchers, professionals, and government agencies
