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?

This tile layer, UEER_Slopes_1m, provides the slope steepness within the boundaries of the Upper Elk River Project, proposed by the U.S. Forest Service in the Monongahela National Forest of West Virginia.Purpose:The data was included to provide additional environmental context for the user’s understanding of the project’s likely environmental impacts.Source & Date:The data was downloaded from the WV Elevation and LIDAR Download Tool, hosted by the West Virginia GIS Technical Center. The data was collected in 2018, and downloaded on 7/20/2021 from (DEM_Mosaic_FEMA_2019-19_Tucker-Randolph_WV_1m_UTM17) and (DEM_Mosaic_FEMA_2016_WV_East_1m_UTM17)Processing:The slope was calculated from the 1-meter LIDAR-derived digital elevation models from two LIDAR projects – FEMA 2016 WV East, and FEMA 2018-19 Tucker-Randolph WV. The slope model was reclassified, as shown below. ABRA published the reclassified mosaic to ArcGIS Online as a tile layer.Symbology:Project Area Slopes (%):0-10%: dark green10-20%: light green20-30%: yellow30-40%: orange40-50%: red>50%: brownMore information can be found on ABRA’s project description page, hosted by the National Forest Integrity Project.

This tile layer describes slope steepness within the boundaries of the Cranberry Spring Creek project, proposed by the U.S. Forest Service in the Monongahela National Forest of West Virginia. Native 1-m resolution data was not available for the entire project area. There is a 3-m resolution version that fills in the gaps. https://abra.maps.arcgis.com/home/item.html?id=89ffd102edc34249858dbb7453c9f7d5Purpose:This data was included to provide additional environmental context for the user’s understanding of the project’s likely environmental impacts.Source & Date:Slope is based on 1m elevation data obtained from the WV Elevation and LIDAR Download Tool on 7/11/2021. https://data.wvgis.wvu.edu/elevation/ - references project: DEM_Mosaic_FEMA_2016_WV_East_1m_UTM17.Processing:The slope was calculated from the 1-meter LIDAR-derived digital elevation model.

This layer, Parsons to Davis Slopes, displays slopes in the vicinity of the proposed Parsons to Davis section of Corridor H. The data associated with this layer was obtained from the WV Elevations and LIDAR Download Tool.Source and date:Elevation and LIDAR data from 2016 was downloaded from the WV Elevations and LIDAR Download Tool as a geodatabase. Accessed in August of 2020.Purpose:The WV Elevations and LIDAR Download Tool was developed to provide downloadable data about land elevation in West Virginia. This can be used to further analyze landforms and various environmental characteristics.Processing:The slope was calculated from the 1-meter LIDAR-derived digital elevation model. The slope model was reclassified, as shown below. ABRA published the reclassified mosaic to ArcGIS Online as a tile layer.Symbolization:The following symbolizations are how they appear in the Parsons to Davis online map provided by ABRA.0 - 3% Slope: blue pixels3 - 5% Slope: light blue pixels5 - 7% Slope: turquoise pixels7 - 10% Slope: green pixels10 - 15% Slope: light green pixels15 - 20% Slope: yellow pixels20 - 25% Slope: light orange pixels25 - 30% Slope: orange pixels30 - 40% Slope: dark orange pixels>40% Slope: red pixels
