U.S. and Canada Lakes represents the major lakes within the United States and Canada.This data set provides five feature classes for displaying the data at different scales. Everything about the feature classes is the same but the level of generalization and its name. The base feature class is called and isn't generalized. The least generalized feature class is called _1, the next more generalized feature class is called _2, and so on. For best performance, use the most appropriate feature class when displaying or printing.

The TIGER/Line Shapefiles are an extract of selected geographic and cartographic information from the Census MAF/TIGER database. The Census MAF/TIGER database represents a seamless national file with no overlaps or gaps between parts. However, each TIGER/Line Shapefile is designed to stand alone as an independent data set or the shapefiles can be combined to cover the whole nation.

This map layer consists of federally owned or administered lands of the United States, Puerto Rico, and the U.S. Virgin Islands. Only areas of 640 acres or more are included. There may be private inholdings within the boundaries of Federal lands in this map layer. This is a revised version of the December 2005 map layer.

U.S. Counties (Generalized) represents the counties of the United States in the 50 states and the District of Columbia. These data were reprojected to USA_Contiguous_Albers_Equal_Area_Conic_USGS_version and clipped to the MAR REA boundary.

A polygon dataset of current and future community footprints in the SNK REA derived from the Tiger/Line File with modification (see the process steps for details). (The TIGER/Line Files are shapefiles and related database files (.dbf) that are an extract of selected geographic and cartographic information from the U.S. Census Bureau's Master Address File / Topologically Integrated Geographic Encoding and Referencing (MAF/TIGER) Database (MTDB). The MTDB represents a seamless national file with no overlaps or gaps between parts, however, each TIGER/Line File is designed to stand alone as an independent data set, or they can be combined to cover the entire nation. The TIGER/Line Files include both incorporated places...

The Northwest Climate Conference (formerly called the Pacific Northwest Climate Science Conference) is the premier climate science event for the region, providing a forum for researchers and practitioners to share scientific results and discuss challenges and solutions related to the impacts of climate change on people, natural resources, and infrastructure in the Northwest. Conference participants include policy- and decision-makers, resource managers, and scientists from academia, public agencies, sovereign tribal nations, non-governmental organizations, and the private sector. More information can be found at the conference website: http://pnwclimateconference.org. The Second Annual Pacific Northwest Climate...

U.S. National Atlas Federal and Indian Land Areas represents the federal- and Indian-owned land areas (for example, Bureau of Indian Affairs, Department of Defense, and Tennessee Valley Authority) of the United States.

The community footprints for the CYR REA were produced by digitally tracing the built areas from satellite imagery. This was done to represent the actual community footprints more accurately than would have been possible from the U.S. Census Bureau’s Topologically Integrated Geographic Encoding and Referencing (TIGER) files. TIGER files are geospatial files with information on several political and administrative units. These shapefiles include polygon boundaries of geographic areas and features, linear features including roads and hydrography, and point features. The communities in Alaska were released as a polygon shapefile, with each community’s boundary identified. However, there were two major concerns with...

U.S. States (Generalized) represents the fifty states and the District of Columbia of the United States.

Two 21-day field operations were conducted in 1997 and 1998 in the estuaries and on the inner continental shelf off the northern Oregon and southern Washington coast. These cruises aboard the R/V Corliss were run in order to generate reconnaissance maps of the seafloor geology and the shallow subsurface stratigraphy using sidescan-sonar and seismic-reflection mapping techniques. The 1998 cruise also collected sediment grab samples, bottom photographs, and video images to verify the sidescan-sonar imagery and to document the seafloor geology. The combination of these data with previously collected sediment sample data (Roberts, 1974; Nittrouer, 1978; and Smith et. al., 1980) has been used to define the extent and...

This dataset represents the planned energy projects that were submitted to the Alaska Energy Authority Renewable Energy Fund Grant Recommendation Program. The dataset contains only projects that are in the "Planned" phase, which can be anywhere from the conceptual design and feasibility phase to nearly completed but not yet functional.

U.S. States (Generalized) represents the 50 states and the District of Columbia of the United States.

A point dataset containing Census population data. This point locations in this dataset are the centroid of the polygon dataset of current community footprints in the SNK REA derived from the Tiger/Line File (see the process steps for details).

The MTDB represents a seamless national file with no overlaps or gaps between parts, however, each TIGER/Line File is designed to stand alone as an independent data set, or they can be combined to cover the entire nation. The TIGER/Line Files include both incorporated places (legal entities) and census designated places or CDPs (statistical entities). An incorporated place is established to provide governmental functions for a concentration...

This coverage contains data representing areas (polygons) of Average Temperature for the period 1971-2000. The data has been converted from grids to polygons. Data can be accessed through the Geospatial Data Gateway http://datagateway.nrcs.usda.gov/.

A map service on the www depicting the location and boundaries of the United States, the District of Columbia and the US territories. It includes common identifiers for these entities so this data set can be used in conjunction with other data sets describing states. This map service uses a generalized states layer for display at small scales. The data are an extract of the Census codes and boundaries from the following Census FTP site: ftp://ftp2.census.gov/geo/tiger. Since the Census data do not include the coastline detail, the coastal boundaries have been spatially clipped to the Health Resources and Services Administration (HRSA) coastline detail. This coastline detail was derived from the Census water blocks...
