Markon and published by CreateSpace. This book was released on 2013-09-14 with total page 46 pages. Available in PDF, EPUB and Kindle. Book excerpt: A land cover map of the National Park Service northwest Alaska management area was produced using digitally processed Landsat data. These and other environmental data were incorporated into a geographic information system to provide baseline information about the nature and extent of resources present in this northwest Alaskan environment. This report details the methodology, depicts vegetation profiles of the surrounding landscape, and describes the different vegetation types mapped. Portions of nine Landsat satellite (multispectral scanner and thematic mapper) scenes were used to produce a land cover map of the Cape Krusenstern National Monument and Noatak National Preserve and to update an existing land cover map of Kobuk Valley National Park Valley National Park. A Bayesian multivariate classifier was applied to the multispectral data sets, followed by the application of ancillary data (elevation, slope, aspect, soils, watersheds, and geology) to enhance the spectral separation of classes into more meaningful vegetation types. The resulting land cover map contains six major land cover categories (forest, shrub, herbaceous, sparse/barren, water, other) and 19 subclasses encompassing 7 million hectares. General narratives of the distribution of the subclasses throughout the project area are given along with vegetation profiles showing common relationships between topographic gradients and vegetation communities.

This book was released on 1999 with total page 404 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Landsat Thematic Mapper (TM) and Multispectral Scanner (MSS) imagery at two different spatial scales were employed during this research effort to provide two medium scale (1:63,360) vegetation maps of the Barrow Region on Alaska's North Slope. Detailed field sampling facilitated a site specific accuracy assessment of the digital classification to provide clues as to the reliability of each map. A comparison of the resultant map products was conducted to assess the effect of the resolution of satellite data on the investigator's ability to accurately interpret vegetation pattern in Arctic tundra. Accuracy assessment of the TM and MSS derived map products indicates that both types of remotely sensed imagery are limited in their ability to accurately represent specific vegetation types at the chosen map scale. The TM instrument, with its improvements in spatial, radiometric, and spectral resolution over the MSS sensor, produced a significantly more accurate vegetation map than that derived from the MSS data. It is concluded that the Landsat derived land cover maps prepared during this investigation provide information on the distribution of general vegetation types across the Barrow Region, but do not provide accurate site-specific vegetation data"--Leaf ii

This book was released on 2013-09-17 with total page 268 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Inventory and Monitoring Program of the National Park Service (NPS) is designed to provide reliable and consistent information for assessing the status and trends in the condition of National Park ecosystems. Vegetation mapping is conducted under the inventory portion of the program in order to provide basic information readily useful for making resource management decisions, and to collect data that can be aggregated on a service-wide level for designing monitoring programs.

Download or read book Vegetation and a Landsat derived Land Cover Map of the Beechey Point Quadrangle Arctic Coastal Plain Alaska written by Donald A. Walker and published by . This book was released on 1987 with total page 63 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report presents a Landsat-derived land cover classification of the Beechey Point, Alaska, 1:250,000-scale quadrangle with descriptions of the major vegetation units. Eight Landsat-level units derived from multispectral scanner data, eleven photo-interpreted units, and eight common vegetation complexes are described. The region is divided into four landscape units: flat thaw-lake plains, gently rolling thaw-lake plains, hill, and flood plains. Area analysis of the quadrangle was done according to townships and nine small study areas. The map uses a modified version of the hierarchical tundra mapping classification of Walker (1983). Area-measurement data from geobotanical maps at eight study sites are compared with similar data from Landsat maps of the same sites. The results indicate that Landsat maps yield area measurements corresponding to broad geobotanical categories. Keywords: Remote sensing; Photogrammetry; Geobotanical mapping.

Book excerpt: The Bureau of Land Management, having jurisdiction over the upper Kuskokwim resource management area, requested the U.S. Geological Survey's Earth Resources Observation Systems Anchorage Field Office to produce a digital land cover map of the area to assist in management activities and policy-making processes. Data are stored at a 50-meter pixel size. The classification of the Landsat multispectral scanner resulted in 7 major classes and 24 subclasses.

Book excerpt: As part of a mapping project conducted by the Alaska State Office of the Bureau of land Management and by Ducks Unlimited, Landsat Thematic Mapper satellite images (acquired September 9, 1999 and September 27, 2000) were used to classify 680,000 acres around Goodnews Bay into seventeen earth cover categories. The area included BLM lands, and surrounding State and Native lands that fall between the BLM lands and Togiak National Wildlife Refuge. Actually, the project area included only a two-mile buffer into the refuge. Data were collected at field sites between July 13 and 17, 2001 aided by helicopters to document the vegetation variation in order to correlate it with satellite imagery during the image classification process. ERDAS Imagine was used to perform the classification. The aim of the project is an integrated GIS database that can be used for improved natural resource planning.
