Modeled Thickness of the Overburden Geomodel Unit (obthk_f)

The obthk_f grid represents the modeled thickness of the Overburden geomodel unit at 
a 500 foot resolution. It is one grid of a geomodel that consists of eleven grids and a spatial extent polygon 
shapefile. As part of a U.S. Geological Survey Groundwater Resources Program study, a three-dimensional 
geomodel was constructed for approximately 53,000 mi2 of the Columbia Plateau in Washington, Oregon, 
and Idaho. This geomodel was constructed to define the general aquifer system geometry for use in a regional 
numerical groundwater flow model. Simplifications and assumptions consistent with this ultimate goal and the 
uncertainty in the available data were made. The geomodel units consist of Miocene age Columbia River Basalt 
Group strata and younger alluvial overburden covering approximately 44,000 mi2. Data were compiled from 
numerous databases and detailed studies completed during the past three decades. These data include 
stratigraphic interpretations made on more than 13,000 wells and a contiguous compilation of surficial geology 
and structural features spanning the study area. These data were simplified and used to construct piecewise-
smooth trend surfaces that represent upper and lower subsurface geomodel unit boundaries in this complex 
folded and faulted terrain.  The smoothness of the surfaces implicitly represents uncertainty in prediction of 
each surface resulting from data gaps, errors in borehole interpretations, errors in mapped contact locations, 
and uncertainty in the shape of the paleo-surface upon which flood basalts were emplaced. Using a rule-based 
algorithm, surfaces were then recombined to construct a fully three-dimensional model with a 500-foot grid 
resolution that is consistent with the data and for which error estimates may be made. The modeling process 
yielded improved estimates of unit volumes, refinement of location of large structural features, and identification 
of features that may be important for ongoing groundwater studies.

Gravity Irrigation Sources on Agricultural Land in the Conterminous United States, 1992: National Resource Inventory Conservation Practice IT01

This data set represents the estimated percentage of the 1-km grid cell that is covered by or subject 
to the agricultural conservation practice (CPIT01), Gravity Irrigation Source (GI) on agricultural land 
by county.  Gravity Irrigation Source is described as irrigation "delivered to the farm and/or field by 
canals or pipelines open to the atmosphere; and, water is distributed by the force of gravity down 
the field by: 1) A surface irrigation system (border, basin, furrow, corrugation, wild flooding, etc.) 
or, 2) Sub- surface irrigation pipelines or ditches." (U.S. Department of Agriculture, 1995)  This 
data set was created with geographic information systems (GIS) and database management tools. 
The acres on which GI's are applied were totaled at the county level in the tabular NRI database 
and then apportioned to a raster coverage of agricultural land within the county based on the 
Enhanced National Land Cover Dataset (NLCDe) 1-kilometer resolution land cover grids 
(Nakagaki, 2003). Federal land is not considered in this analysis because NRI does not 
record information on those lands.

Bedrock Data from Western Cape Cod, Massachusetts (WELLSITE shapefile, Geographic, NAD27)

Cores collected from recent drilling in western Cape Cod, Massachusetts provide insight into the topography and petrology of the underlying bedrock.  Cores from 64 drill sites spread over a approximately 140 km2 study area produced samples of granitoids (31), orthogneisses (20), basalts/diabases (4), amphibolites (3), felsic mylonites (2), and dolomitic rock (2).
Granitoid composition ranges from granite to tonalite and quartz diorite, but it is dominated by two-feldspar granites.  Hydrothermal alteration is common in nearly all cores as evidenced by the secondary growth of chlorite and epidote.  Granitoids resemble rocks of the Dedham and Fall River plutons (Wones and Goldsmith, 1991).  Gneisses generally contain the mineral assemblage K-feldspar+plagioclase+quartz+/-biotite+/-
chlorite+/-muscovite+/-sphene+/-epidote+oxides.  Amphibolites contain the assemblage hornblende+plagioclase+quartz+biotite+epidote+/-chlorite+/-sphen+/-K-feldspar+/-sericite+
oxides.  Peak metamorphic grade based on mineral assemblages is estimated at lower amphibolite facies.  X-ray powder diffraction of unmetamorphosed dolomitic cores shows presence of layered silicates (clays), plagioclase, and possible magnesite.
Contours of the bedrock surface show locally irregular topography suggesting erosion by glacial scour.  Lithologic distribution mapping suggests a possible continuation of the New Bedford gneissic terrane that outcrops 25 km to the west.  Dolomitic rocks may represent a lithified fault gauge material at the eastern edge of the gneissic zone.  Basalts/diabases are interpreted to be post-metamorphic dikes associated with Mesozoic rifting.

LANDFIRE Remap 2016 Existing Vegetation Cover (EVC) CONUS

LANDFIRE's (LF) Existing Vegetation Cover (EVC) represents the vertically projected percent cover of the live canopy for a 30-m cell. EVC is produced separately for tree, shrub, and herbaceous lifeforms. Training data depicting percentages of canopy cover are obtained from plot-level ground-based visual assessments and lidar observations. These are combined with Landsat imagery (from multiple seasons), topographic, climate, and other geospatial data sets to inform models built independently for each lifeform. Tree, shrub, and herbaceous lifeforms each have a potential range from 10% to 100%. The three independent lifeform datasets are merged into a single product. The EVC product is then reconciled through QA/QC measures to ensure lifeform is synchronized with both Existing Vegetation Height (EVH) and Type (EVT) products. Disturbance events not visible in the source imagery are accounted for by incorporating LF Remap Annual Disturbance products. LF uses EVC as an input for LF Remap Fuel Vegetation Cover (FVC).

24-bit True Color SW Quadrant of RINCON NE, Orthophoto Production for Puerto Rico and US Virgin Island (rincon4_2004.tif)

This dataset is a single orthoimage from a collection of GeoTIFF format natural color orthoimages covering the islands of Puerto Rico, Mona, Desecheo, Culebra, Vieques, and the US Virgin Islands.
An orthophoto is remotely sensed image data in which displacement of features in the image caused by terrain relief and sensor orientation have been mathematically removed. Orthophotography combines the image characteristics of a photograph with the geometric qualities of a map. Each orthophoto provides imagery for a nominal 3.75 minute (in latitude and longitude) cell area. The source imagery was obtained in October 2004 and used to produce orthophotos with a one meter ground resolution. Imagery was acquired at 0.86 meter ground sample distance (GSD) resolution. Flight height maintained during mission was 27,000 feet AGL. The imagery was captured at 12-bit radiometric resolution and converted to 8-bit radiometric resolution during post processing. The imagery was obtained and processed by all digital means beginning with data acquisition using a Leica ADS40 Digital Airborne Sensor. The orthophotos are available in GeoTIFF form. The projected coordinate system is UTM zone 19 N, NAD 83, GRS 80, Units Meters.

NANA1M.TIF -  Anacapa Island Reserve sidescan sonar backscatter image in nearshore Benthic Habitat mapping Project S. California map Series. (UTM 10N, NAD83)

The sidescan sonar image of the nearshore seafloor (0 to 100 m water depths) of the Big Sycamore reserve area was mosaicked from data collected in 1998.  A Klein 2000 sidescan system was used for geophysical surveying.  A Triton Elics Isis brand side-scan data recording system was used on the cruise.  The 1998 survey was navigated with a Leica Differential Global Positioning System (DGPS) which provided a ship position with accuracy of 1-5 m in DGPS mode. At times during the cruise differential signal was interrupted. In non-differential mode, the receiver provided a position with 30-50 m accuracy. A KVH Industries Inc. azimuth digital gyro-compass provided ship headings with 0.5 degree accuracy. Navigation data were recorded using Yo-Nav version 1.19 (Gann, 1992). The sidescan fish was towed approximately 30 m above the seafloor. The distance of the fish behind the ship was not known during this survey and must be estimated when the data are processed in order to produce the sidescan image mosaics.  The resolution of the processed data mosaics is 0.2 m.  The data are presented here at a resolution of 1 m.  This is one of a collection of digital files of a geographic information system of spatially referenced data related to the USGS Coastal and Marine Geology Program Nearshore Benthic Habitat Mapping Project.

Estimates of agricultural expenses in counties in the conterminous United States as reported in the 1987 Census of Agriculture

This coverage contains estimates of agricultural expenses in counties in
the conterminous United States as reported in the 1987 Census of
Agriculture (U.S. Department of Commerce, 1989a). Agricultural expenses
data are reported in thousands of dollars. Agricultural expenses estimates
were generated from surveys of all farms where $1,000 or more of
agricultural products were sold, or normally would have been sold, during
the census year.
		
Most of the attributes summarized represent 1987 data, but some
information from the 1982 Census of Agriculture also was included.
		
The polygons representing county boundaries in the conterminous United
States, as well as lakes, estuaries, and other nonland-area features were
derived from the Digital Line Graph (DLG) files representing the
1:2,000,000-scale map in the National Atlas of the United States (1970).

RES2DINV format continuous resistivity profiling data collected in the Indian River Bay, Delaware, on April 13, 2010, on U.S. Geological Survey Field Activity 2010-006-FA

A geophysical survey to delineate the fresh-saline groundwater interface and associated sub-bottom sedimentary structures beneath Indian River Bay, Delaware, was carried out in April 2010. This included surveying at higher spatial resolution in the vicinity of a study site at Holts Landing, where intensive onshore and offshore studies were subsequently completed. The total length of continuous resistivity profiling (CRP) survey lines was 145 kilometers (km), with 36 km of chirp seismic lines surveyed around the perimeter of the bay. Medium-resolution CRP surveying was performed using a 50-meter streamer in a bay-wide grid. Results of the surveying and data inversion showed the presence of many buried paleochannels beneath Indian River Bay that generally extended perpendicular from the shoreline in areas of modern tributaries, tidal creeks, and marshes. An especially wide and deep paleochannel system was imaged in the southeastern part of the bay near White Creek. Many paleochannels also had high-resistivity anomalies corresponding to low-salinity groundwater plumes associated with them, likely due to the presence of fine-grained estuarine mud and peats in the channel fills that act as submarine confining units. Where present, these units allow plumes of low-salinity groundwater that was recharged onshore to move beyond the shoreline, creating a complex fresh-saline groundwater interface in the subsurface. The properties of this interface are important considerations in construction of accurate coastal groundwater flow models. These models are required to help predict how nutrient-rich groundwater, recharged in agricultural watersheds such as this one, makes its way into coastal bays and impacts surface water quality and estuarine ecosystems. For more information on the survey conducted for this project, see https://cmgds.marine.usgs.gov/fan_info.php?fan=2010-006-FA.

Contours--Offshore of San Gregorio, California

This part of SIM 3306 presents data for the bathymetric contours for several seafloor maps of the Offshore of San Gregorio map area, California. The vector data file is included in "Contours_OffshoreSanGregorio.zip," which is accessible from https://pubs.usgs.gov/ds/781/OffshoreSanGregorio/data_catalog_OffshoreSanGregorio.html. These data accompany the pamphlet and map sheets of Cochrane, G.R., Dartnell, P., Greene, H.G., Watt, J.T., Golden, N.E., Endris, C.A., Phillips, E.L., Hartwell, S.R., Johnson, S.Y., Kvitek, R.G., Erdey, M.D., Bretz, C.K., Manson, M.W., Sliter, R.W., Ross, S.L., Dieter, B.E., and Chin, J.L.

10-m interval contours of the Offshore of San Gregorio map area, California, were generated from bathymetry data collected by Fugro Pelagos and by California State University, Monterey Bay, Seafloor Mapping Lab (CSUMB). Mapping was completed in 2006 and 2007, using a combination of 400-kHz Reson 7125 and 244-kHz Reson 8101 multibeam echosounders. These mapping missions combined to collect bathymetry from about the 10-m isobath to beyond the 3-nautical-mile limit of California's State Waters. Bathymetric contours at 10-m intervals were generated from the merged 2-m bathymetric surface. The most continuous contour segments were preserved while smaller segments and isolated island polygons were excluded from the final output. Contours were smoothed via a polynomial approximation with exponential kernel (PAEK) algorithm using a tolerance value of 60 m. The contours were then clipped to the boundary of the map area.
