FEMA, utilizing Axis Geospatial, LLC (Axis), collected 2,640 square miles of LiDAR data in the West Virginia counties of Mineral, Hampshire, Grant, Hardy and Pendleton. 1ft contours created from lidar-derived bare earth DEM dataset using ArcGIS software. Contours are labeled as intermediate or index with index contours set to every 5th interval. Horizontal accuracy is not performed on the contours. The data was developed based on a horizontal projection/datum of NAD83 UTM Zone 17, meters and vertical datum of NAVD88 (GEOID12B).

Quantum Spatial, Inc collected December 21, 2016 lidar data for several counties in southeast West Virginia, covering approximately 3,485 square miles. The nominal pulse spacing (NPS) for this project is 0.7 meters. These lidar data are processed classified LAS 1.4 files, formatted to 4,320 individual 1,500-meter x 1,500-meter tiles, used to create intensity images, 3D breaklines, 1-meter hydro-flattened DEMs, and contours with an interval of 1-foot. The data was developed based on a horizontal projection/datum of NAD83 UTM Zone 17, meters and vertical datum of NAVD88 (GEOID12B), meters and a vertical accuracy of 6.7 cm.
