The USGS Library, managed by CSAS&L, supports all fundamental scientific research conducted within USGS. It serves both internal and external customers with comprehensive access to literature, data, and information necessary understand USGS mission areas and make critical decisions about how to proceed with research initiatives and investigations in the earth and natural sciences.
The USGS took over responsibility for mapping the country in 1879 and has been the primary civilian mapping agency of the United States ever since. The best known USGS maps are the 1:24,000-scale topographic maps, also known as 7.5-minute quadrangles. More than 55,000 7.5-minute maps were made to cover the 48 conterminous States.
The National Map is a collaborative effort among the USGS and other Federal, State, and local partners to improve and deliver topographic information for the Nation. It has many uses ranging from recreation to scientific analysis to emergency response. The National Map is easily accessible for display on the Web, as products and services, and as downloadable data.
This U.S. Geological Survey project consists of two primary studies about long-term land-cover change in the Delaware River Basin, particularly in Pennsylvania. The objectives for these projects were to address and quantify predominant affects and outcomes of land-surface change in urbanizing areas.
The U.S. Geological Survey National Geospatial Technical Operations Center (NGTOC) provides leadership and world-class technical expertise in the acquisition and management of trusted geospatial data, services, and map products for the Nation. NGTOC supports The National Map as part of the National Geospatial Program.
U.S. Geological Survey: a History of the National Program for Topographic Mapping (1884–2009) Topographic maps became a signature product of the USGS because the public found them - then and now - to be a critical and versatile tool for viewing the nation's vast landscape.
The CDI is a collaboration of USGS scientists, data managers, policy experts, and other organizations that promote data integration capabilities and data management best practices. It is an instrumental community of practice for leveraging expertise and resources to test new technologies and institutionalize best practices.
Standards and specifications are essential to facilitate the development and sharing of geospatial data and products. The USGS standards and specifications define the requirements to ensure that all products and data prepared by the USGS under the National Geospatial Program are consistent in accuracy, structure, format, style, and content.
The Geographic Names Information System (GNIS) is the Federal standard for geographic names. The U.S. Geological Survey developed the GNIS in support of the U.S. Board on Geographic Names as the official repository of domestic geographic names for the Federal Government, and the source for applying geographic names to Federal electronic and printed products.
USGS topographic maps originally published on paper in the period 1884-2006 have been scanned and published as PDF documents. This collection is of topographic quadrangle maps with scales between 1:10,000 and 1:250,000. These historic documents are downloadable free of charge through several interfaces.
Using crowd-sourcing techniques, the US Geological Survey’s Volunteered Geographic Information project known as “The National Map Corps (TNMCorps)” encourages citizen volunteers to collect and edit data about man-made structures in an effort to provide accurate and authoritative spatial map data for the USGS National Geospatial Program’s web-based The National Map and US Topo Maps.
US Topo maps are modeled on the familiar 7.5-minute, 1:24,000-scale quadrangle maps of the period 1947-1992, but are mass-produced from national GIS databases on a 3-year cycle.The maps are layered PDF documents with geospatial extensions. They are downloadable free of charge through several interfaces.
Orthoimagery data typically are high resolution aerial images that combine the visual attributes of an aerial photograph with the spatial accuracy and reliability of a planimetric map. The National Map offers public domain, 1-meter orthoimagery for the conterminous United States with many urban areas and other locations at 2-foot or finer resolution.
The National Map offers a collection of small-scale datasets, most of which are at 1:1,000,000. The National Map publishes two data collections at one million-scale: one for Global Map users and one for National Map users. In terms of vector geometry, the lines, points, and areas in these data collections are identical. The difference is in the attributes assigned to these features.
OBIS-USA is the US Node of the Ocean Biogeographic Information System, providing the collection and distribution point to OBIS of marine biogeographic records in U.S. waters or collected with U.S. funding. Using the Darwin Core standard, OBIS-USA integrates and makes accessible data on marine species presence, absence, and abundance to aid scientists, resource managers, and decisions makers.
Data and web services from NFHP’s 2010 and 2015 assessments of streams and estuaries, as well as other data contributed by Fish Habitat Partnerships, are available for download and use via the NFHP Data System. The results of the national assessment can also be viewed online using the National Assessment Results Viewer.
Mandated by Congress, all states and U.S. territories must develop a State Wildlife Action Plan every ten years, outlining the steps that are needed for conservation in their state or territory before wildlife and habitats become too rare or costly to restore. The Species Conservation Analysis Tool provides a national look at Species of Greatest Conservation Need as reported in those plans.
The USGS Data Release Workbench provides a user-friendly view of USGS data release requirements, in line with with Federal Open Data and Open Access goals, and allows USGS researchers to track progress toward releasing their data.
The USGS Science Data Catalog serves as a single access point for public USGS scientific datasets and as a conduit to external catalogs in response to Federal Open Data requirements. The SDC allows the public to access USGS datasets through text and GIS-based search; topical browse, and keyword, mission area, data source, and scientist faceting.
The ARC activity’s mission is to provide high-performance computing (HPC) capabilities and expertise to USGS scientists for the acceleration and expansion of scientific discovery. Machine access, training workshops, and project consultations are provided to USGS researches in need of these advanced computing capabilities.
myUSGS offers an access-controlled online suite of science collaborative tools, ideal for use by USGS scientists and their research teams as well as by other communities of practice involving USGS and its partners.
The Metadata Wizard tool helps geospatial data users with the creation and editing of metadata compliant with the Federal Geographic Data Committee's 'Content Standard for Digital Geospatial Metadata' (FGDC-CSDGM).
The OME is an online metadata creation tool that allows scientists to document their data using the FGDC Content Standard for Digital Geospatial Metadata by answering simple questions about their data.
ScienceBase is data and information management infrastructure that enables data upload, documentation, sharing, and dynamic data services using standards-compliant methods and technological components.

A Systems Thinking approach to post-disaster restoration of maritime transportation systems
A Systems Thinking approach is used to examine elements of a maritime transportation system that are most likely to be impacted by an extreme event. The majority of the literature uses a high-level view that can fail to capture the damage at the sub-system elements. This work uses a system dynamics simulation for a better view and understanding of...Lespier, Lizzette Pérez; Long, Suzanna K.; Shoberg, Thomas G.
