Science Datasets

The data collected and the techniques used by USGS scientists should conform to or reference national and international standards and protocols if they exist and when they are relevant and appropriate. For datasets of a given type, and if national or international metadata standards exist, the data are indexed with metadata that facilitates access and integration.

Mean annual water-budget components for Hawaii Island, Hawaii, for recent conditions, 1916-83 rainfall and 2008 land cover

The shapefile associated with this metadata file represents the spatial distribution of mean annual
water-budget components, in inches, for Hawaii Island, Hawaii. The water-budget components in
the shapefile were computed by a water-budget model for a scenario representative of recent
conditions (1916-83 rainfall and 2008 land cover), as described in USGS Scientific...

Maximum inundation limits resulting from hypothetical dam failure of the Lago El Guineo Dam, Orocovis, Puerto Rico, under sunny day condition - polygon shapefile

The U.S. Geological Survey, in cooperation with the Puerto Rico Electric Power Authority, completed a hydrologic and hydraulic analysis to assess the potential hazard to human life and property associated with the hypothetical failure of the Lago El Guineo Dam. The Lago El Guineo Dam is within the headwaters of the Río Grande de Manatí and impounds a drainage area of about 4....

Modeled conterminous United States Crop Cover datasets for 2005

Crop cover maps have become widely used in a range of research applications. Multiple crop cover maps have been developed to suite particular research interests. The National Agricultural Statistics Service (NASS) Cropland Data Layers (CDL) are a series of commonly used crop cover maps for the conterminous United States (CONUS) that span from 2008-2013. In this investigation we wanted to...

Photographs from the Blue Ridge Parkway in Virginia (Woolwine region)

This dataset contains photographs keyed to station points along the Blue Ridge Parkway in Virginia. Photographs are titled and arranged by 7.5-minute quadrangle, and station points are located in the "Detailed geologic mapping geodatabase for the Blue Ridge Parkway in Virginia." The first part of the photograph's filename corresponds to the FieldID attribute of the PhotoPoints entity in the...

USGS BOEM PaCSEA Raw Observation Data

To ensure comparable spatial and temporal coverage with similar historic datasets, we flew 32 east-west-oriented uniform transects (spaced at 15' latitude [27.8-km] intervals) when possible to the 2000-m isobath (includes shelf, slope, and rise waters). At the request of BOEM, we included six focal-area surveys nested within the overall broad transect survey area. Each focal-area survey...

EAARL Coastal Topography--Assateague Island National Seashore, Maryland and Virginia, 2002: First Surface

ASCII XYZ point cloud data were produced from remotely sensed, geographically referenced elevation measurements acquired cooperatively by the U.S. Geological Survey (USGS) and the National Park Service (NPS). Elevation measurements were collected over Assateague Island National Seashore using the first-generation National Aeronautics and Space Administration (NASA) Experimental Advanced...

Base of aquifer contours for the Northern High Plains aquifer

Several pre-existing datasets that characterize portions of the
Northern High Plains aquifer base were merged together in order
to define the entire base of the Northern High Plains aquifer. This
digital dataset consists of the aquifer base elevation contours
(100-foot contour interval) for the northern portion of the High Plains
aquifer in the central United...

WLCI - Important Agricultural Lands Assessment (Input Raster: NLCD Lands Classified as Hay/Pasture or Cultivated Crops)

This dataset represents numerical values denoting a binary identification of whether a particular condition is met. In this case, values represent whether a given land parcel (represented as a pixel) is classified as "Hay/Pasture" or "Cultivated Crops" (pixels will be assigned a value of 1), or not (all pixels not in one of these categories will be assigned a value of 0). This raster is one of...
