Study area boundary for the  Death Valley regional ground-water flow system, Nevada and California

This digital data set represents the Death Valley regional ground-water flow system (DVRFS) study area which 
encompasses approximately 100,000-square kilometers in Nevada and California and is bounded by latitudes 
35-degrees north and 38-degrees 15-minutes north and by longitudes 115-degrees west and 118-degrees west. 
The study area boundary encompasses the DVRFS model domain which is the area simulated by a transient 
ground-water flow model. The DVRFS transient ground-water flow model is the most recent in a number of 
regional-scale models developed by the U.S. Geological Survey (USGS) for the U.S. Department of Energy 
(DOE) to support investigations at the Nevada Test Site (NTS) and at Yucca Mountain, Nevada (see "Larger

LANDFIRE Remap 2016 Biophysical Settings (BPS) CONUS

LANDFIRE's (LF) Biophysical Settings (BPS) product (https://www.landfire.gov/bps.php) represents the vegetation system that may have been dominant on the landscape prior to Euro-American settlement. BPS is based on both the current biophysical environment and an approximation of the historical disturbance regime. Map units are based on NatureServe's Ecological Systems classification and represent the natural plant communities that may have been present during the reference period. Each BPS map unit is matched with a model of vegetation succession and both serve as key inputs to the LANDSUM landscape succession model (Keane et al. 2006). The actual time period for this data set is determined by historical context provided by the fire regime, vegetation system dynamics modeling, and the recent field and geospatial inputs used to create it. Weather data from the Daily Surface Weather and Climatological Summaries database [(DAYMET) https://daymet.ornl.gov/) were compiled from 1980 to 1997. LF uses BPS to depict reference conditions of vegetation systems across landscapes and should not be regarded as a representation of existing vegetation. LF Remap BPS is unchanged from LF Nationals BPS except for updates made to water, barren and snow classes (additions or removal), so that not vegetated cover types within the spatial BPS product matches LF existing vegetation and fuel products.

2005 Post-Hurricane Katrina EAARL Lidar-Derived Dune Crest, Toe and Shoreline

The Storm-Induced Coastal Change Hazards component of the National Assessment of Coastal Change Hazards project focuses on understanding the magnitude and variability of extreme storm impacts on sandy beaches. Lidar-derived beach morphologic features such as dune crest, toe and shoreline help define the vulnerability of the beach to storm impacts. This dataset defines the elevation and position of the seaward-most dune crest and toe and the mean high water shoreline derived from the 2005 Post-Hurricane Katrina (Mississippi to Florida) Experimental Advanced Airborne Research Lidar (EAARL) survey. Beach width is included and is defined as the distance between the dune toe and shoreline along a cross-shore profile. The beach slope is calculated using this beach width and the elevation of the shoreline and dune toe.

Footprints of Lidar Datasets Published at the U.S. Geological Survey St. Petersburg Coastal and Marine Science Center Since 2001

U.S. Geological Survey (USGS) staff created geographic information system (GIS) footprints to show the extent of light detection and ranging (lidar) datasets published by the USGS St. Petersburg Coastal and Marine Science Center (SPCMSC), since 2001. These lidar datasets were published as LAS, XYZ, or Digital Elevation Model (DEM) outputs of coastal, submerged and/or terrestrial topography in USGS Data Series (DS), Open-File Reports (OFR), and data releases (DR). Please see the publications listed in the source information section of this metadata record for details on data acquisition and processing of the datasets included in this data release. Using tools included in Global Mapper (GM) GIS software, polygons were generated to represent the coverage area of data provided in multiple USGS lidar publications. These footprints were later merged into one shapefile containing information about the field activity number (fan), field activity source link (fan_url; added in version 2.0), publication type (pub), publication source link (pub_url), lidar return type (returntype), and year the data were collected (yr_collect) to serve as an easily accessible data inventory. This data release will be updated and versioned, as needed, as more lidar publications are released from the USGS SPCMSC.

Digital Shoreline Analysis System version 4.1 Transects with Short-Term Rate Calculations for the New England North region from Popham Beach, Maine to the northern side of Cape Ann, Massachusetts (NewEnglandN_ST.shp)

Sandy ocean beaches are a popular recreational destination, often surrounded by communities containing valuable real estate.  Development is on the rise despite the fact that coastal infrastructure is subjected to flooding and erosion.  As a result, there is an increased demand for accurate information regarding past and present shoreline changes.  To meet these national needs, the Coastal and Marine Geology Program of the U.S. Geological Survey (USGS) is compiling existing reliable historical shoreline data along open-ocean sandy shores of the conterminous United States and parts of Alaska and Hawaii under the National Assessment of Shoreline Change project.
There is no widely accepted standard for analyzing shoreline change.  Existing shoreline data measurements and rate calculation methods vary from study to study and prevent combining results into state-wide or regional assessments.  The impetus behind the National Assessment project was to develop a standardized method of measuring changes in shoreline position that is consistent from coast to coast.  The goal was to facilitate the process of periodically and systematically updating the results in an internally consistent manner.

Conservation Tillage Systems on Agricultural Land in the Conterminous United States, 1992: National Resource Inventory Conservation Practice 329

This data set represents the estimated percentage of the 1-km grid cell that is covered by or subject to the 
agricultural conservation practice (CP329 ), Conservation Tillage Systems (CTS) on agricultural land by county.  
Conservation Tillage Systems is described as "managing the amount, orientation and distribution of crop and 
other plant residues on the soil surface year-round, while growing crops in narrow slots, or tilled or residue 
free strips in soil previously untilled by full-width inversion implements." (U.S. Department of Agriculture, 1995) 
This data set was created with geographic information systems (GIS) and database management tools. The 
acres on which CTS'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.

Probability of Elevated Volatile Organic Compound (VOC) Concentrations in Groundwater in the Eagle River Watershed Valley-Fill Aquifer, Eagle County, North-Central Colorado, 2006-2007

This raster data set delineates the predicted probability of elevated volatile organic compound (VOC) 
concentrations in groundwater in the Eagle River watershed valley-fill aquifer, Eagle County, North-Central 
Colorado, 2006-2007. This data set was developed by a cooperative project between the U.S. Geological 
Survey, Eagle County, the Eagle River Water and Sanitation District, the Town of Eagle, the Town of 
Gypsum, and the Upper Eagle Regional Water Authority. This project was designed to evaluate potential 
land-development effects on groundwater and surface-water resources so that informed land-use and 
water management decisions can be made. This groundwater probability map and its associated probability 
maps was developed as follows: (1) A point data set of wells with groundwater quality and groundwater 
age data was overlaid with thematic layers of anthropogenic (related to human activities) and hydrogeologic 
data by using a geographic information system to assign each well values for depth to groundwater, 
distance to major streams and canals, distance to gypsum beds, precipitation, soils, and well depth. 
These data then were downloaded to a statistical software package for analysis by logistic regression. 
(2) Statistical models predicting the probability of elevated nitrate concentrations, the probability of 
unmixed young water (using chlorofluorocarbon-11 concentrations and tritium activities), and the 
probability of elevated volatile organic compound concentrations were developed using logistic regression 
techniques. (3) The statistical models were entered into a GIS and the probability map was constructed.
