Newberry Volcano, one of the largest Quaternary volcanoes in the conterminous United States, is a broad shield-shaped volcano measuring 60 km north-south by 30 km east-west with a maximum elevation of more than 2 km above sea level. It is the product of deposits from thousands of eruptions, including at least 25 in (approximately) the last 12,000 years (the Holocene Epoch). Newberry Volcano has erupted as recently as 1,300 years ago, but isotopic ages indicate that the volcano began its growth as early as 0.6 million years ago. Such a long eruptive history together with recent activity suggests that Newberry Volcano is likely to erupt in the future. This DEM (digital elevation model) of Newberry Volcano contributes...

This layer of the National Elevation Dataset (NED) is 2 arc-second (approximately 60 m) resolution. The 2 arc-second NED are derived from diverse source data that are processed to a common coordinate system and unit of vertical measure. These data are distributed in geographic coordinates in units of decimal degrees, and in conformance with the North American Datum of 1983 (NAD 83). All elevation values are in meters and, over the continental United States, are referenced to the North American Vertical Datum of 1988 (NAVD88). The 2 arc-second NED layer provides seamless coverage of Alaska. The 2 arc-second NED layer is available as pre-staged products tiled in 1 degree blocks in Erdas .img, ESRI arc-grid, and grid...

The Topographic and Bathymetric Shaded Relief of North America map layer shows depth and elevation ranges using colors, with relief enhanced by shading. The image was derived from two pre-existing map layers; the Bathymetric Shaded Relief of North America, derived from ETOPO2 data, and the Color North America Shaded Relief, derived from GTOPO30 data.

The Louisiana State Legislature created Coastal Wetlands Planning, Protection, and Restoration Act (CWPPRA) in order to conserve, restore, create and enhance Louisiana's coastal wetlands. The wetland restoration plans developed pursuant to these acts specifically require an evaluation of the effectiveness of each coastal wetlands restoration project in achieving long-term solutions to arresting coastal wetlands loss. This data set includes mosaicked aerial photographs for the Pelican Island and Pass La Mer to Chaland Pass Resoration (BA-38) project for 2005, 2007, 2011, and 2013. This data is used as a basemap habitat classification. It also serves as a visual tool for project managers to help them identify any...

The North America Shaded Relief data were derived from the GTOPO30 elevation data. GTOPO30 is a global digital elevation model (DEM) with a horizontal grid spacing of 30 arc seconds (approximately 1 kilometer). GTOPO30 was derived from several raster and vector sources of topographic information. It was developed between 1993 and 1996 through a collaborative effort led by staff at the U.S. Geological Survey's EROS Data Center (EDC). The following organizations participated by contributing funding or source data: the National Aeronautics and Space Administration (NASA), the United Nations Environment Programme/Global Resource Information Database (UNEP/GRID), the U.S. Agency for International Development (USAID),...

Investigations of coastal change and coastal resources often require continuous elevation profiles from the seafloor to coastal terrestrial landscapes. Differences in elevation data collection in the terrestrial and marine environments result in separate elevation products that may not share a vertical datum. This data release contains the assimilation of multiple elevation products into a continuous digital elevation model at a resolution of 3-arcseconds (approximately 90 meters) from the terrestrial landscape to the seafloor for the contiguous U.S., focused on the coastal interface. All datasets were converted to a consistent horizontal datum, the North American Datum of 1983, but the native vertical datum for...

This dataset represents slope in degrees for the Northeast region, including Canada. Slope is a measure of change in elevation. This dataset is derived from the following source: 30 meter Digital Elevation Model (DEM) for the Northeast (projected to NAD 83 Albers) that was created by mosaicking two datasets: 1. U.S. Geological Survey's (USGS) 30 meter National Elevation Dataset (NED), ~1 arc-second data that is updated over large areas by integrating the 10 meter or better source data (where available), re-sampled to 1 arc-second. 2.

A continuous 2km raster Digital Elevation Model (DEM) for the Great Northern Landscape Conservation Cooperative (GNLCC) study area. This DEM was complied for analysis of topographic effects on climate within the GNLCC study area, as a part of the GNLCC Fire Refugia Project. The DEM was complied from USGS National Elevation Dataset (NED) (http://ned.usgs.gov/), the British Columbia Gridded Digital Elevation Model Product (http://geobc.gov.bc.ca/base-mapping/imagery/products/gridded.html), and the NASA ASTER GDEM (http://asterweb.jpl.nasa.gov/gdem.asp), mosaicked, and sinks were filled in ArcGIS.

contains digital elevation models in TIFF format for salt marshes surveyed within the Humboldt Bay during the summer of 2012 and the spring of 2013. Climate change scenarios typically address top-down global to continental scale changes; thus, few are easily interpretable to local land managers or contain vertical resolution that is useful at the local level for developing climate change adaptation strategies. Our studies support a bottom-up local approach to evaluating SLR effects at the parcel scale providing information and data sets useful in assessing responses. We collect comprehensive, detailed site-specific data that are used to model marsh ecological response from SLR and storms. By implementing this approach...

This dataset represents a shaded relief, or hillshade, for the Northern U.S. and Canada. This shaded relief raster was created from a 30 meter Digital Elevation Model (DEM) using the ArcMap geoprocessing tool "hillshade". The DEM consists of two mosaiced datasets: 1. U.S. Geological Survey's (USGS) 30 meter National Elevation Dataset (NED) , ~1 arc-second data that is updated over large areas by integrating the 10 meter or better source data(where available), re-sampled to 1 arc-second. 2. The Canadian Digital Elevation Data, Level 1 (CDED1) The Center of Topographic Information (CTI) jointly produces the CDED with federal, provincial, and territorial government agencies as well as the private sector.

Explanation: New elevation technologies and datasets now give DEM users better accuracies and spatial resolutions, increased areas of seamless coverage, and more choices than in the past. This poster shows, left to right, the surface expression of Colorado as is contained in the National Elevation Dataset (NED) DEM data, airborne IFSAR (Interferometric Synthetic Aperture RADAR) elevation of the Front Range area, a visual comparison between IFSAR and LIDAR (LASER/Light Detection and Ranging) surfaces for the Morrison 7.5-minute quadrangle, and a more quantitative surface comparison for a portion of the Morrison quadrangle. Processes have been developed to merge IFSAR or LIDAR elevation with IFSAR or optical orthoimagery,...

U.S. Geological Survey, Department of the Interior - The annual lidar and DEM acquisition plan is part of the 3DEP initiative to systematically collect enhanced elevation data (Quality Level 2) in the form of high-quality light detection and ranging (lidar) data over the conterminous United States, Hawaii, and the territories on an 8-year schedule. The FY17 acquisition plan currently anticipates collecting 225,000 sq. mi. or more depending on partnerships and other contributions to the plan. Interested parties who wish to become a funding partner with the USGS in FY17 or in future years should contact a USGS Geospatial Liaison - http://liaisons.usgs.gov/geospatial/documents/TNM_Partnership_User_ContactList.pdf....

The USGS Shaded Relief Large service from The National Map (TNM) was created from the National Elevation Dataset (NED), a seamless dataset of best available raster elevation data for the conterminous United States, Alaska, Hawaii, and Territorial Islands of the US. Derived from the NED using a hill shade technique, this base map represents a continental view showing shaded relief from USGS NED layers at resolutions of 1/3-, 1-, and 2-arc-second (in Alaska only). This hillshade is actually five separate shaded relief datasets created from the original terrain data. Each shaded relief has different azimuths and altitude values as follows: 0 45, 135 60, 270 45, 315 45, 45 45. These five datasets are then combined into...
