The Virginia Department of Transportation (VDOT) Geologic Sections dataset consists of site-specific, large-scale geologic cross-sections (composite sheets). These sections were acquired from VDOT in order to save them from disposal. There are 5,500 geological profiles created for highway construction projects containing extensive core, auger and split-spoon logs at scales of 1:50 and 1:100 providing a unique record of subsurface geological and geotechnical data along roadways throughout Virginia. The thousands of feet of vertical subsurface data represents millions of dollars of investment in data acquisition by VDOT. The sections are useful as indicators of subsurface geology in large parts of Virginia. ...

The Daggs Tank 7.5-minute Quadrangle is located approximately 40 miles (60 km) northwest of downtown Phoenix on the east side of Hassayampa Plain. Much of the map area consists of the western piedmont of the White Tank Mountains, but the western third of the map area is dominated by deposits of the south-flowing Hassayampa River, a major regional drainage in central Arizona. The surficial geology depicted in this map is modified from Field and Pearthree (1991b), and includes new field mapping and aerial photograph interpretation using high-resolution digital images provided by Maricopa County. Tertiary volcanic rocks were mapped for this study, but much of the rest of the bedrock was mapped by Barret (1976) and...

These files were used to construct corridors estimating the extent of new coastal corridors exposed by reduced lake levels. They are included here to show the available horizontal extent of lidar-derived topo-bathymetric data and thus explicitly identify gaps and limitations of predicted corridor extents under various reduced lake level scenarios. In addition, these files provide users with a background layer that depicts the topographic variability of the submerged near-shore lake bed and terrestrial landscape.These files are 5m grid representations of the hydrographic and topographic data collected by the CHARTS system along the coasts of the U.S. sides of Lake Michigan, Lake Huron, Lake St. Clair, Lake Erie,...

This collection of maps shows relative habitat quality for a suite of species that use riparian overstory habitats. Component layers include: tree patch size, presence and complexity of riparian understory, and abundance of tamarisk. Associated layers such as river channels at high flow and bottomland reaches are included for reference.

From the USGS EarthExplorer about information: The USGS EarthExplorer (EE) tool provides users the ability to query, search, and order satellite images, aerial photographs, and cartographic products from several sources. In addition to data from the Landsat missions and a variety of other data providers, EE now provides access to MODIS land data products from the NASA Terra and Aqua missions, and ASTER level-1B data products over the U.S. and Territories from the NASA ASTER mission. Registered users of EE have access to more features than guest users.

Current national data resources for GAP include three primary data sets – land cover, protected areas, and species. Land Cover: The GAP/LANDFIRE National Terrestrial Ecosystems data, based on the NatureServe Ecological Systems Classification, are the foundation of the most detailed, consistent map of vegetation available for the United States. These data facilitate the planning and management for biological diversity on a regional and national scale. Learn more about GAP land cover data here: https://www.usgs.gov/core-science-systems/science-analytics-and-synthesis/gap/science/land-cover Protected Areas: The Protected Areas Database of the United States (PAD-US) is a national geodatabase, created by USGS GAP,...

ZIP File in Geographic NAD 1927 Projection. Map of the alluvial valley of the Mississippi River from the head of St. Francis Basin to the Gulf of Mexico, showing lands subject to overflow, location of levees and trans-alluvial profiles Downloaded from: https://www.digitalcommonwealth.org/search/commonwealth:7h14b0450 Edited (to correct position of panels) and georeferenced by Yvonne Allen (USFWS) to geographic NAD1927 using ArcGIS , 3rd order polynomial and 80 ground control points using lat lon grid.
This data layer summarizes ecological systems and land cover classes described in state-level and national-level maps as Broadly Defined Habitats for groups of species of conservation concern. Each grid cell in the raster is assigned a Condition Index value based on desired condition metrics using ancillary datasets and a decision tree approach for each assessed habitat. Grid cells are also assigned bar code descriptors indicating which metrics contributed to the Condition Index score for that cell. This layer also contains information about potential habitats based on the LANDFIRE Biophysical Settings data layer. This layer was developed to support the next iteration of the Conservation Blueprint developed by the...

This dataset presents measures of landscape fragmentation calculated by FRAGSTATS at 4KM and HUC5 reporting unit levels. Fragmentation integrates the influence of urban, agriculture, invasive vegetation, roads, pipelines, utility lines, oil/gas wells, and water on patches of natural vegetation.
