    Monroe County, West Virginia
    Description

    These raster datasets are 3-meter lidar-derived images of Monroe County, West Virginia, and were created using geographic information systems (GIS) software. Lidar-derived elevation data acquired in late December of 2016 were used to create a 3-meter resolution working digital elevation model (DEM), from which a hillshade was applied and a topographic position index (TPI) raster was calculated. These two rasters were uploaded into GlobalMapper, where the TPI raster was made partially transparent and overlaid the hillshade DEM. The resulting image was exported to create a 3-meter resolution lidar-derived image. The data is projected in North America Datum (NAD) 1983 UTM Zone 17.

    Description

    This dataset consists of 575,670 point locations across the state of West Virginia. Those mapped to the “slpF” class (n = 116,413) were interpreted to be initiation locations of slope failures (e.g., landslides, debris flows, rock topples, etc.). Each slope failure location was collected as a point feature at the interpreted slope failure initiation location by an analyst then subsequently checked by another interpreter. Interpretation primarily relied on light detection and ranging (LiDAR)-derived hillshades and slopeshades and other ancillary geospatial data. All non-slope failure points are labeled as “not” (n=459,257) and were collected as random points at least 30 meters away from the mapped slope failure locations and occurring within the state extent. The “not” points serve as pseudo-absence samples. All topographic variables were derived from a 2 m spatial resolution digital terrain model (DTM) produced from LiDAR data. For topographic measures requiring a moving window, a circular window with a 7 cell radius was used. Physiographic regions are defined relative to Major Land Resource Areas (MLRAs): https://www.nrcs.usda.gov/resources/data-and-reports/major-land-resource-area-mlra. The wvSlpFailures.csv file provides only the attributes while the wvSlpFailures.shp file includes the spatial coordinates. We have included a Word document and PDF that further describes the data.

    Description

    Monroe County in southeastern West Virginia hosts world-class karst within carbonate units of Mississippian and Ordovician age. Lidar-derived elevation data acquired in late December of 2016 were used to create a 3-meter resolution working digital elevation model (DEM), from which surface depressions were identified using a semi-automated workflow in ArcGIS®. Depressions in the automated inventory were systematically checked by a geologist within a grid of 1.5 square kilometer tiles using aerial imagery, lidar-derived imagery, and 3D viewing of the lidar imagery. Distinguishing features such as modification by human activities or hydrological significance (stream sink, ephemerally ponded, etc.) were noted wherever relevant to a particular depression. Relative confidence in depression identification was provided and determined by whether the depression was visible in the lidar imagery, aerial imagery, or both. Statistics on the geometric morphometry of each depression were calculated in ...

    Description

    This imagery dataset consists of 3-meter resolution, lidar-derived imagery of the Elkins 30 x 60 minute quadrangle in Virginia and West Virginia. The source data used to construct this imagery consists of 1-meter lidar-derived digital elevation models (DEMs). The lidar source data were compiled from different acquisitions published between 2015 and 2021. The data were processed using geographic information systems (GIS) software. The data is projected in WGS 1984. This representation illustrates the terrain as a hillshade with contrast adjusted to highlight local relief according to a topographic position index (TPI) calculation.

    Description

    This study mapped land cover (water, bare ground, forest, grass, marsh, algal flat, building, bridge culvert, and agriculture) around Matagorda Bay, Texas. The study area was defined by a 2-km buffer around the West Matagorda Bay shoreline and extended from the western portion of the Colorado River Delta through the eastern portion of Matagorda Island, Texas. This study incorporated WorldView-2 (WV-2; acquired on 2012-11-17, 2013-05-05, and 2013-12-16) and lidar (acquired 2018-01-04 - 2018-02-23 and 2019-01-24 – 2019-01-29) to obtain a 2-m resolution habitat map for the entire study area. A novel stacked classification approach was developed to take advantage of high-resolution satellite imagery and airborne lidar point clouds. Ultimately, a rule-based classifier was stacked on a group of machine learning classifiers for multispectral images and a filter classifier for lidar point clouds. The data were created for the Texas Office of the Comptroller project titled “Matagorda Bay Ecosystem Assessment.†Maps of vegetation, sand, and water coverage for discrete dates from 1850 to 2020 are available in related dataset HI.x833.000:0020 (https://doi.org/10.7266/zs2f74bj).

Description

WVDEP LiDAR data was collected by the Natural Resource Analysis Center at WVU under contract with the West Virginia Department of Environmental Protection, Division of Mining and Reclamation.The data was collected between 04/09/2010 and 12/13/2011 during leaf-off, snow and flood free conditions in the spring and fall.The data format is 1.5x1.5 km LAS v1.2 files in UTM 17 NAD83 (CORS96), NAVD88 (GEOID09). Contractor software initially classified ground returns for comprehensive and bare earth tiles, but did not perform other classifications. The Technical Applications and GIS (TAGIS) unit at the WVDEP performed Quality control checking and error correction on a tile-by-tile basis before creating derived products and edited LAS files.Hardware and flight parameters:Scanner: Optech ALTM-3100Post Spacing (Average): 3.3 ft / 1.0 meterFlying Height (Above Ground Level): 5,000-ft / 1,524 metersAverage Ground Speed: 135 knots (155 MPH)Scanner Pulse Rate Frequency: 70,000 HzScanner Frequency / Field of View: 35 Hz / 36 degrees (18 half angle)Overlap (Average): 30%In-depth metadata is available here, halfway down the page:LiDAR MetadataDownloads also available here:TAGIS LiDAR WebAppTAGIS LiDAR RepositoryLooking for 3DEP LiDAR?
