The geologic map was created in GSMAP at Socorro, New Mexico by Orin Anderson and Glen Jones and published as the Geologic Map of New Mexico 1:500,000 in GSMAP format in 1994. This graphic file was converted to ARC/INFO format by Greb Green and GlenJones and released as the Geologic Map of New Mexico in ARC/INFO format in 1997.

The mining claim density data of federal lands in Oregon are combined with the digital Oregon Public Land Survey (PLS) to create a digital map of the density of mine claims in Open-File Report 99-541. The mining claim density data of federal lands in Oregon was one of 13 western states released in Open-File Report 99-325. The database for Oregon was converted to an Arc/Info file and connected with the PLS by an Arc/Info relate. As stated in OF 99-325, "These mining claim density databases were created from data obtained in March 1997, from the Mining Claim Recordation System (MCRS) of the Bureau of Land Management. These databases provide mining claim density information in a tabular form. They quantify the status...

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 website offers results from the project “Impacts of climate change on ecology and habitats of waterbirds”, which evaluates projected impacts of climate, urbanization, and water management scenarios on ecology and habitats of waterfowl and other waterbirds in the Central Valley of California.The Central Valley (CVCA) of California contains some of the most important habitats for waterfowl, shorebirds, and other waterbirds in North America. Most waterbird habitats in the CVCA which include wetlands, flooded rice fields, and other agricultural lands, rely on managed surface water supplies stored in reservoirs and delivered via a complex, interconnected system to a wide array of competing water users. Downscaled...
This online database (https://www.streamcontinuity.org/cdb2/naacc_search_crossing.cfm) serves as a common repository for road-stream crossing assessment data assembled by the North Atlantic Aquatic Connectivity Collaborative (NAACC). Both a network of partners and a source of shared resources, the NAACC offers a collaborative framework for taking on the critical task of assessing and upgrading the hundreds of thousands of outdated road-stream crossings across the region that represent barriers to wildlife movement and pose flooding risks to communities. The NAACC offers training in standard protocols for conducting assessments, online tools for prioritizing upgrades based on ecological benefits, and this database...

Data Basin is a science-based mapping and analysis platform that supports learning, research, and sustainable environmental stewardship. As environmental conservation problems become more serious and the demand to solve them grows more urgent, it is critical that science, practice, policy, and people are integrated in stronger ways. A team of scientists, software engineers, and educators at the Conservation Biology Institute (CBI) built Data Basin with the strong conviction that we can expand our individual and collective ability to develop sustainable solutions by empowering more people through access to spatial data, non-technical tools, and collaborative networks. The core of Data Basin is free and provides...

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.

This map layer shows areal and linear water features of the United States, Puerto Rico, and the U.S. Virgin Islands. The original file was produced by joining the individual State hydrography layers from the 1:2,000,000- scale Digital Line Graph (DLG) data produced by the USGS. This map layer was formerly distributed as Hydrography Features of the United States. This is a revised version of the January 2003 map layer.

The USGS National Elevation Dataset (NED) has been developed by merging the highest-resolution, best quality elevation data available across the United States into a seamless raster format. NED is the result of the maturation of the USGS effort to provide 1:24,000-scale Digital Elevation Model (DEM) data for the conterminous US and 1:63,360-scale DEM data for Alaska. The dataset provides seamless coverage of the United States, HI, AK, and the island territories. NED has a consistent projection (Geographic), resolution (1 arc second), and elevation units (meters). The horizontal datum is NAD83, except for AK, which is NAD27. The vertical datum is NAVD88, except for AK, which is NAVD29. NED is a living dataset that...
