Download or read book Wetland and Environmental Applications of GIS written by John G. Lyon and published by CRC Press. This book was released on 1995-09-18 with total page 414 pages. Available in PDF, EPUB and Kindle. Book excerpt: This new book presents powerful techniques that can be used to address issues and problems related to wetlands and surface waters. It is the first book of its kind to address inventory and management of wetlands and water quality problems using GIS and remote sensing technologies. Wetland and Environmental Applications of GIS describes a variety of techniques, applications, and case studies for evaluating wetland and surface water characteristics at the landscape scale. The book details wetland and environmentally-oriented surface water resource studies using spatial and spectral based technologies such as GIS, remote sensing, computer modeling, and image display. Introductory material is included in the first section to provide a common background and to refresh or introduce concepts to the professional. The second section details applications of these technologies in studies of wetlands, including the use of GIS and archival satellite data in evaluating and measuring sediment types, water depth, and environmental change in the coastal wetlands of the Great Lakes. The third section addresses various environmental applications of GIS, such as locating non-point pollution sources and managing oil spills. The final section supplies additional information and applications, with particular emphasis on potential contributions of remote sensing.
Download or read book Wetland Landscape Characterization written by John G. Lyon and published by CRC Press. This book was released on 2001-03-01 with total page 144 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book was written to assist scientists, engineers, technicians and other resource managers in the evaluation of wetland boundaries and characteristics. Powerful tools - GIS, mapping, remote sensing - are described and demonstrated using practical applications and combined to yield landscape ecological data, and ecological risk assessments. Using numerous technical methods, Wetland Landscape Characterization shows you how to evaluate the presence of wetlands, and the stressors, exposures and ecological systems - streams, lakes, terrestial - that influence their condition. A vital component of the book is the variety of quality assurance/quality control and accuracy assessment techniques presented throughout the text. A thorough understanding of these methods is critical to the success of your project.
Download or read book The Application of Geographic Information Systems for Delineation and Classification of Tidal Wetlands for Resource Management of Oregon s Coastal Watersheds written by Russell Wellington Scranton and published by . This book was released on 2004 with total page 210 pages. Available in PDF, EPUB and Kindle. Book excerpt: Resource managers of Oregon's tidal wetlands require an improved GIS layer for management of existing tidal wetland habitat and areas considered for tidal wetland restoration. A reconnaissance project was initiated, such that interpretations of remote sensing data, the National Wetland Inventory, Oregon Estuary Plan Book and additional management tools were used to create a "tidal wetland" in an ArcGIS Geodatabase, for Oregon's coastal estuaries, excluding the Columbia River. With an improved hydrologic delineation of tidal waters and channels this data set classifies existing tidal wetlands for future resource management use based on the Hydrogeomorphic (HGM) classification (adopted nationally and by the State of Oregon) and for habitat classification based on the Oregon Estuary Plan Book classification system. The classification "restoration consideration areas" was developed for lands where restoration of tidal circulation might be geotechnically feasible pending further investigations. Additional groundwork and validation of the data set classification's is recommended before this interpretation is used as an official reference for resource management. In addition to wetland classification this project was partly developed to provide a GIS base layer, which when combined with supplementary data sets, would enhance the ability of resource mangers and citizens to prioritize tidal wetland restoration efforts and evaluate the ecological integrity of an individual tidal wetlands or an entire estuarine complex. A simple spatial analysis of this data set's classification system by watershed and comparison to the Oregon State of the Environment Report 2000 (SER) shows improvements to total existing tidal marsh habitat. It also shows that the SER underestimated the total habitat lost due to anthropogenic alteration based on information and techniques available for their assessment. Additional development of the data set may enhance management of Goals 16 and 17 of Oregon's Statewide Planning Goals Guidelines, aid in management of non-point source pollution and the designation Critical Habitat and restoration priorities for the endangered Coastal Coho. Resource managers and citizens will be able to view and interpret this data set and supporting documentation at the OSU Library or in part online at the Oregon Coastal Atlas (www.coastalatlas.net).
Download or read book Correlating Enhanced National Wetlands Inventory Data with Wetland Functions for Watershed Assessments written by U. S. Fish U.S. Fish and Wildlife Service and published by CreateSpace. This book was released on 2015-02-14 with total page 30 pages. Available in PDF, EPUB and Kindle. Book excerpt: The U.S. Fish and Wildlife Service has been conducting the National Wetlands Inventory for over 25 years. The NWI Program has produced wetland maps for 91% (78% final) of the lower 48 states, all of Hawaii, and 35% of Alaska. Wetlands are classified according to the Service's official wetland classification system (Cowardin et al. 1979). This classification describes wetlands by ecological system (Marine, Estuarine, Lacustrine, Riverine, and Palustrine), by subsystem (e.g., water depth, exposure to tides), class (vegetative life form or substrate type), subclass, water regimes (hydrology), water chemistry (pH and salinity), and special modifiers (e.g., alterations by humans). The maps have been converted to digital data for 47% of the lower 48 states and 18% of Alaska. The availability of digital data and geographic information system (GIS) technology make it possible to use NWI data for various geospatial analyses.

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.
