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.

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 Leveraging Freely Available Remote Sensing and Ancillary Datasets for Semi Automated Identification of Potential Wetland Areas Using a Geographic Information System GIS written by Benjamin R. Felton and published by . This book was released on 2016 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this study was to develop a wetland identification tool that makes use of freely available geospatial datasets to identify potential wetland locations at a spatial scale relevant for transportation corridor assessments. The tool was developed to assist the Virginia Department of Transportation in wetland identification over large geographic regions. Wetland identification is an integral part of many construction projects performed by state departments of transportation. However, current methods for wetland identification in support of these activities are lacking in one or more of the following ways: inadequate use of ancillary data, little automation, failure to leverage freely available data, excessive computation times, high expense, or the requiring of software not typically available to state departments of transportation. This study addressed these limitations through development of a GIS-based wetland screening tool with freely available data and automated geoprocessing workflows to assist in wetland identification over large geographic regions. The tool was designed as a screening tool able to identify potential wetland areas that would require further investigation by a trained wetland identification expert. Therefore, the tool was designed to minimize false negatives: cases where the tool incorrectly designates wetland as non-wetland. Application of the tool to a study region with detailed wetland delineations showed that the tool correctly identified wetlands nearly 70% of the time, produced false positives 24% of the time, and produced false negatives only 6% of the time. The tool allows decision makers to adjust the sensitivity of the wetland identification algorithm in order to decrease false negatives at the expense of increasing the fraction of the study area identified as potential wetland. The tool, therefore, allows decision makers to balance trade-offs between the amount of area requiring more detailed wetland identification and the frequency with which wetland areas are misidentified by the screening tool as false negatives. Although the wetland identification tool was shown to be effective, future studies will be required to calibrate and validate the tool further using a broader range of application areas. The study recommends that this be done by way of additional corridor analyses to facilitate further improvements to the tool.

Download or read book Data Mining GIS and Remote Sensing written by Bo Zhang and published by . This book was released on 2008 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: The Prairie Pothole Region in the United States contains millions of seasonal, semipermanent, or permanent lakes and wetlands that typically range in size from 0.1 to 10 hectares. These lakes and wetlands are vulnerable to climate change, especially in our study area of South Dakota, in which a period of deluge following a sharp drought considerably expanded the areal extent of prairie pothole lakes during the last decade of the twentieth century. Preliminary estimates of lake areas, determined using Landsat 5 and 7 images, had appreciable errors especially for the smallest of these lakes. We developed a new sub-pixel approach integrated with a Classification and Regression Tree (CART) model using a Geographical Information System (GIS) to quantify mixed water pixels along lake boundaries to improve the area estimations for pothole lakes. Errors in estimated area were typically 10 percent or less for lakes greater than 1 hectare in size.
Download or read book The Application of Remote Sensing and GIS for Improving Modeling the Response of Wetland Vegetation Communities to Water Level Fluctuations at Long Point Ontario written by Jingwen Huang and published by . This book was released on 2016 with total page 89 pages. Available in PDF, EPUB and Kindle. Book excerpt: Coastal wetlands are complex and dynamic environments which are of high environmental, social, and economic importance. With the acceleration of climate change and global warming, it is necessary to monitor and protect dynamic coastal wetlands. Wetland ecosystem simulation modeling is one approach to help produce better wetland protection and management strategies. The application of remote sensing and Geographic Information System (GIS) in wetland ecosystem simulation models can help with better spatial modeling of wetland ecosystems. In addition, coastal topographic models can achieve digital representations of terrain surfaces and aquatic environments. This study applies remote sensing and GIS technologies for improving wetland vegetation simulation modeling. First, the study integrates multiple topographic data sources (i.e. Light Detection and Ranging data (LiDAR) and bathymetry data) to generate a coastal topographic model. Shoreline data are involved in the generation process. Second, a pre-existing wetland simulation model is updated to a new version to model the response of wetland vegetation communities to water level fluctuations at Long Point, Ontario. Third, different coastal topographic models have been employed to explore how a coastal topographic model affects the wetland simulation results. Model sensitivity analysis is conducted to explore the variation of model simulation results to different vegetation transition baselines parameter. Findings from this study suggest that a high accuracy coastal topographic model could yield a higher accuracy simulation result in a wetland ecosystem simulation model. Second, the application of remote sensing and the integration of multiple topographic data (e.g. LiDAR data and bathymetry data) could provide high accuracy and high density elevation information in coastal area, especially in land-water transitional areas. Finally, a narrower vegetation transition baseline increases the possibility for a wetland community shift to a wetter wetland community.
