The Shuttle Radar Topography Mission (SRTM) was a partnership between NASA and the National Geospatial-Intelligence Agency (NGA). Flown aboard the NASA Space Shuttle Endeavour (11-22 February 2000), SRTM fulfilled its mission to map the world in three dimensions. The USGS is under agreement with NGA and NASA's Jet Propulsion Laboratory to distribute SRTM elevation products derived from the C-band radar data. SRTM utilized interferometric C-band Spaceborne Imaging Radar to generate elevation data over 80 percent of the Earth's land surface. Global SRTM data at a resolution of 1 arc-second have been edited to delineate and flatten water bodies, better define coastlines, remove spikes and wells, and fill small voids. Larger areas of missing data or voids were filled by the NGA using interpolation algorithms in conjunction with other sources of elevation data. The SRTM 1 Arc-Second Global data offer worldwide coverage of void filled data at a resolution of 1 arc-second (30 meters) and provide open distribution of this high-resolution global data set.

In August 2008, the National Geophysical Data Center (NGDC), an office of the National Oceanic and Atmospheric Administration (NOAA), developed the ETOPO1 Global Relief Model as an improvement to the ETOPO2v2 Global Relief Model. ETOPO1 is available in "Ice Surface" (top of Antarctic and Greenland ice sheets) and "Bedrock" (base of the ice sheets) versions. Both versions of ETOPO1 were generated from diverse global and regional digital data sets, which were shifted to common horizontal and vertical datums, and then evaluated and edited as needed. Bathymetric, topographic, and shoreline data used in ETOPO1 were obtained from NGDC, Antarctic Digital Database (ADD), European Ice Sheet Modeling Initiative (EISMINT), Scientific Committee on Antarctic Research (SCAR), Japan Oceanographic Data Center (JODC), Caspian Environment Programme (CEP), Mediterranean Science Commission (CIESM), National Aeronautics and Space Administration (NASA), National Snow and Ice Data Center (NSIDC), Scripps Institute of Oceanography (SIO), and Leibniz Institute for Baltic Sea Research (LIBSR). ETOPO1 is vertically referenced to sea level, and horizontally referenced to the World Geodetic System of 1984 (WGS 84). Cell size for ETOPO1 is 1 arc-minute.

<p> The ability to monitor microbial contamination remains a critical technique in the mitigation of risk to crew health and vehicle systems during human spaceflight missions. Current methods of bacterial and fungal monitoring on the International Space Station (ISS) depend on culturing of microorganisms during spaceflight and subsequent ground-based identification. This approach requires substantial crew time, uses consumables with short shelf lives, and prevents a rapid response to microbial contamination. To address these limitations for future missions beyond low-Earth orbit, a biosensor using gold nanoparticles is being developed for the rapid detection of medically significant microorganisms. For proof-of-concept, we have targeted the detection of Staphylococcus aureus, a common infectious agent that has been repeatedly isolated aboard the ISS. Gold nanoparticles were modified by the covalent attachment of an antibody that has a high binding affinity for a protein on the cell wall of S. aureus. Upon interaction with a sample containing S. aureus, binding between the nanoparticles and the bacteria occurred rapidly. A significant reduction in the red coloration of the colloidal nanoparticle suspension, and the formation of a large purple pellet was observed following a brief centrifugation step. Comparison of the absorbance spectra verified the visual observation, demonstrating that there was a significant reduction in the absorbance of the supernatants of reaction samples in which S. aureus was present. This biosensing system provides a rapid means to specifically detect only the targeted organism. Further development will potentially lead to a small, lightweight biosensor that can be easily adapted to detect other selected microorganisms in real-time, providing crews of future spaceflight missions a simple method to autonomously define potential infectious disease risks.</p>

The National Land Cover Database (NLCD) Land Cover Collection is produced through a cooperative project conducted by the Multi-Resolution Land Characteristics (MRLC) Consortium (www.mrlc.gov). The MRLC Consortium is a partnership of Federal agencies, consisting of the U.S. Geological Survey, the National Oceanic and Atmospheric Administration, the U.S. Environmental Protection Agency, the U.S. Department of Agriculture (USDA) National Agricultural Statistics Service, the U.S. Forest Service, the National Park Service, the U.S. Fish and Wildlife Service, the Bureau of Land Management, NASA, and the U.S. Army Corps of Engineers. A primary goal of the MRLC Consortium is to generate current, consistent, and seamless national datasets of land cover, percent developed imperviousness, and percent tree canopy. NLCD 2001 land cover was created by partitioning the conterminous United States into 66 mapping zones, based on ecoregion and geographical characteristics, edge matching features, and the size requirement of Landsat mosaics. NLCD 2001 represents a seamless assembly of land cover for all 66 MRLC mapping zones. NLCD 2001 land cover was developed for all 50 states and Puerto Rico / U.S. Virgin Islands. NLCD 2006 land cover was created on a path/row basis and mosaicked to create a seamless national product. NLCD 2006 land cover was developed for the conterminous United States. NLCD 2011 land cover was created on a path/row basis and mosaicked to create a seamless national product. The data in NLCD 2011 are completely integrated with NLCD 2001 and NLCD 2006. As part of the NLCD 2011 project, the NLCD 2001 and 2006 land cover data products were revised and reissued to provide full compatibility with the new NLCD 2011 products. NLCD 2011 land cover was developed for the conterminous United States and Alaska. Questions about the NLCD Land Cover Collection can be directed to the NLCD land cover mapping team at USGS EROS, Sioux Falls, SD (605) 594-6151 or mrlc@usgs.gov.

This table contains data on the annual miles traveled by place of occurrence and by mode of transportation (vehicle, pedestrian, bicycle), for California, its regions, counties, and cities/towns. The ratio uses data from the California Department of Transportation, the U.S. Department of Transportation, and the U.S. Census Bureau. The table is part of a series of indicators in the Healthy Communities Data and Indicators Project of the Office of Health Equity. Miles traveled by individuals and their choice of mode – car, truck, public transit, walking or bicycling – have a major impact on mobility and population health. Miles traveled by automobile offers extraordinary personal mobility and independence, but it is also associated with air pollution, greenhouse gas emissions linked to global warming, road traffic injuries, and sedentary lifestyles. Active modes of transport – bicycling and walking alone and in combination with public transit – offer opportunities for physical activity, which has many documented health benefits. More information about the data table and a data dictionary can be found in the About/Attachments section.
