Results 71 - 80 of 151 listed alphabetically [list by similarity]
PDF Land-use and land-cover scenarios and spatial modeling at the regional scale [More info]
Complex geographic information can be analyzed with mathematical models to show us the spatial patterns of human building, vegetation growth, and other landscape characteristics that may result from environmental changes we may expect in the future.
PDF Land-use planning for nearshore ecosystem services--the Puget Sound Ecosystem Portfolio Model [More info]
Describes the types of concerns and observations used to help area resource managers analyze actual or potential changes in this highly developed ecosystem.
PDF Landscape consequences of natural gas extraction in Allegheny and Susquehanna Counties, Pennsylvania, 2004--2010 [More info]
Quantifies the landscape changes and consequences of natural gas extraction by digitizing indications of disturbance on NAIP aerial photographs and using these with the NLCD to show land use-land cover change.
PDF Landscape consequences of natural gas extraction in Bradford and Washington Counties, Pennsylvania, 2004-2010 [More info]
Quantifies the landscape changes and consequences of natural gas extraction by digitizing indications of disturbance on NAIP aerial photographs and using these with the NLCD to show land use-land cover change.
PDF Mapping grasslands suitable for cellulosic biofuels in the Greater Platte River Basin, United States [More info]
Study to identify grasslands that may be suitable for cellulosic feedstock production. Producing ethanol from non-cropland areas such as grassland will minimize the effects of biofuel developments on global food supplies.
PDF Mapping, monitoring, and modeling Western Gateway Community landscape dynamics [More info]
Geospatial analysis of factors affecting communities that are adjacent to Federal lands, especially those lands subject to varying public interest and visitation.
PDF Methods for estimating magnitude and frequency of floods in rural basins in the southeastern United States: South Carolina [More info]
Flood estimates are needed for the efficient design of bridges, highway embankments, levees, to protect lives and property in flood-prone areas, and to determine flood-insurance rates.
Middleton (Wisconsin) Data Center [More info]
Technical information about several water resource database projects with local, regional, and national scope including the National Environmental Methods Index, the National Water Quality Assessment Data Warehouse, and the USGS Publications Warehouse.
Mineral deposit models [More info]
Publications by the USGS on mineral deposit models converted to digital files that can be downloaded. Some are *.pdf files requiring Adobe Acrobat Reader to view and download text
National Geomagnetism Program [More info]
Overview of USGS programs related to geomagnetism including observatories, data, program services, links to models, charts, and movies, program contacts, Intermagnet, Geomag, publications, and bibliographies.
