Product: Washington FEMA HQ Classified Lidar point cloud.

Geographic Extent: This dataset and derived products encompass the Washington FEMA HQ Lidar dataset, an area covering approximately 3,450,211 acres of QL2 data in Washington State spanning both UTM Zones 10 and 11 in the following 5 counties: Whitman, Skamania, Cowlitz, Clark, and Klickitat. A QL1 survey area in Pend Orielle County was...

Hydro-Flattened Bare Earth DTM. The dataset was created using the lidar bare earth points and 3D hydro breaklines to a resolution of 1 m (April 2018). Voids exist in the data due to data redaction conducted under the guidance of the United States Secret Service. All lidar data returns and collected data were removed from the dataset based on the redaction footprint shapefile generated in 2017.This is a MD iMAP hosted service.

Dewberry collected LiDAR for ~3,942 square miles in various Virginia, West Virginia, and Maryland Counties. The acquisition was performed by Geodigital. This metadata covers the LiDAR produced for the Washington County project area. The nominal pulse spacing for this project is 1.6 ft (0.5 meters). This project was collected with a sensor which collects intensity values for each discrete pulse extracted from the waveform. GPS Week Time, Intensity, Flightline and echo number attributes were provided for each LiDAR point. Dewberry used proprietary procedures to classify the LAS according to contract specifications: 1-Unclassified, 2-Ground, 7-Noise, 9-Water, 10-Ignored Ground due to breakline proximity, and 11-Withheld. Dewberry produced 3D breaklines and combined these with the final LiDAR data to produce seamless hydro flattened DEMs for the 638 tiles (1500 m x 1500 m) that cover this deliverable.This is a MD iMAP hosted service.

Geographic Extent: SANDY_Restoration_VA_MD_DC_QL2 Area of Interest covers approximately 2,002 square miles. Lot #5 contains the full project area Dataset Description: The SANDY_Restoration_VA_MD_DC_QL2 project called for the Planning, Acquisition, processing and derivative products of LiDAR data to be collected at a nominal pulse spacing (NPS) of 0.7 meters. Project specifications are based on the U.S. Geological Survey National Geospatial Program Base LiDAR Specification, Version 1. The data was developed based on a horizontal projection/datum of UTM Zone 18 North, NAD83, meters and vertical datum of NAVD1988 (GEOID12A), meters. LiDAR data was delivered in RAW flight line swath format, processed to create Classified LAS 1.2 Files formatted to 2283 individual 1500m x 1500m tiles, and corresponding Intensity Images and Bare Earth DEMs tiled to the same 1500m x 1500m schema, and Breaklines in ESRI Shapefile format. The data was then converted to a horizontal projection/datum of NAD83 Maryland State Plane Coordinate System, Meters. LiDAR was delivered in Classified LAS 1.2 Files formatted to 328 individual 800 meter x 800 meter tiles, and corresponding Intensity Images and Bare Earth DEMs tiled to the same 800 meter x 800 meter schema, and Breaklines in ESRI Shapefile format. Ground Conditions: LiDAR was collected in Winter 2014, while no snow was on the ground and rivers were at or below normal levels. In order to post process the LiDAR data to meet task order specifications, Quantum Spatial established a total of 59 QA control points and 95 Land Cover control points that were used to calibrate the LiDAR to known ground locations established throughout the SANDY_Restoration_VA_MD_DC_QL2 project area.This is a MD iMAP hosted service.

The survey areas cover eastern portions of the Upper Okanogan River in Canada, the Lower Okanogan River in Washington State, and Lake Roosevelt in Washington State. The study areas total ~560 square kilometers. These lidar were acquired for all the areas identified for the purpose of stream channel assessment and potential stream restoration design.

The U.S. DOI Office of Surface Mining Reclamation and Enforcement funded this aerial LiDAR and aerial imagery survey. The dataset covers the John Henry Mine (surface coal mine) in Washington.

The intended use of the data is to support the corresponding mine teams on current and future projects. Example use cases include: precise area and volumetric measurements, assisting with upcoming TOJs (Termination of Jurisdictions) and bond releases, change detection analysis, monitoring the progression and reclamation of mining, and visualizing 3D models.

Terrapoint collected Light Detection and Ranging (LiDAR) data contributing to the Puget Sound Lowlands project of 2005. Lynnwood, Snohomish County, Washington. This data set covers approximately 14 square miles. The Airborne LiDAR survey was conducted using Terrapoint's 40 kHz ALTMS (Airborne Laser Terrain Mapping System), flying at an optimum height of 3500 ft AGL at 140 knots. The system consists of a 36-degree full angle laser, a Trimble 4700 GPS receiver and a Honeywell H764 IMU unit. This metadata is a collaboration of metadata reports from each of the individual 15 projects. The Puget Sound Lowlands project covers more areas over 2000-2004, these areas were excluded for this project.

The U.S. DOI Office of Surface Mining Reclamation and Enforcement funded this aerial LiDAR and aerial imagery survey. The dataset covers the Centralia Mine (surface coal mine) in Washington.

The intended use of the data is to support the corresponding mine teams on current and future projects. Example use cases include: precise area and volumetric measurements, assisting with upcoming TOJs (Termination of Jurisdictions) and bond releases, change detection analysis, monitoring the progression and reclamation of mining, and visualizing 3D models.

LIDAR_PROJECT_POLY: Data consists of polygons representing the spatial footprints of LIDAR projects over BLM lands in Oregon and Washington.

The Kittitas AOI consists of two areas. These areas were to be collected to the 'highest' accuracy requirement. Ground Control is collected throughout the AOI for use in the processing of LiDAR data to ensure data accurately represents the ground surface. QA/QC checkpoints, (FVA and CVA - see Ground Control process step for further information) are located throughout the area, and are used for independent quality checks of the processed LiDAR data. LiDAR acquisition products include Pre- and Post- flight reports which contain information on the flightlines, equipment parameters, and other pertinant acquisition details. The LiDAR Point Cloud product consists of tiles of LAS points which are partially classified such that the bare earth points can be calibrated to the ground surface and tested via the independent QC to ensure the ground surface is accurately represented. The LiDAR processing product consists of LAS points which are fully classified with the bare earth points tested via the independent QC to ensure the ground surface is accurately represented.

These lidar data were collected on October 12 to November 9, 2006 by Watershed Sciences Incorporated for the Puget Sound Lidar Consortium, with funding from the US Bureau of Reclamation. The survey areas cover eastern portions of the the Methow River and Wenatchee River in Washington State. The study areas total ~360 square kilometers. These lidar were acquired for all the areas identified for the purpose of stream channel assessment and potential stream restoration design.
