1   USGS Lidar Point Cloud NY CMPG 2013 LAS 2015
 
Description
Lidar (Light detection and ranging) discrete-return point cloud data are available in the American Society for Photogrammetry and Remote Sensing (ASPRS) LAS format. The LAS format is a standardized binary format for storing 3-dimensional point cloud data and point attributes along with header information and variable length records specific to the data. Millions of data points are stored as a 3-dimensional data cloud as a series of x (longitude), y (latitude) and z (elevation) points. A few older projects in this collection are in ASCII format. Please refer to http://www.asprs.org/Committee-General/LASer-LAS-File-Format-Exchange-Activities.html for additional information.

7   City of Surrey, British Columbia, Canada
 
Description
To support various Capital Engineering Projects, the City of Surrey conducted a comprehensive Airborne Remote Sensing data acquisition project between March and May of 2013. This data is made publically available as part of Surrey's Open Data Initiative, and is available in bulk. The following remote sensing data is available:
-High resolution Light Distance And Ranging (Lidar) Data (25+ pts/m2)
-72 Band HyperSpectral Imagery (1 metre pixel resolution)
-3 Band Orthorectified Imagery (10 cm pixel resolution)

While these data were acquired for specific capital engineering projects, there is value inherent within them that others can realize. The City will monitor innovative applications of the City's Open Data to establish the extent and frequency of future remote sensing data acquisition. Direct any questions regarding the application of this data to Bill McKay (BDMcKay at surrey dot ca or 604 591-4868).

8   2012 Louisa County VA Lidar
 
Description
The primary purpose of this project was to develop a consistent and accurate surface elevation dataset derived from high-accuracy Light Detection and Ranging (Lidar) technology for the USGS Louisa, Virginia Project Area. The Lidar data were processed to a bare-earth digital terrain model (DTM). Detailed breaklines and bare-earth Digital Elevation Models (DEMs) were produced for the project area. Deliverables were produced in both UTM and State Plane coordinates. The data was formatted according to tiles with each UTM tile covering an area of 1,000 meters by 1,000 meters and each State Plane tile covering an area of 2,500 feet by 2,500 feet. A total of 797 UTM tiles and 1,338 State Plane tiles were produced for the project encompassing an area of approximately 277 sq.miles.

9   2010 / 2011 Shenandoah Valley Lidar - sv2area
 
Description
Dewberry served as the prime contractor for the project. In addition to project management, Dewberry processed the LAS tiles to the initial ground classification. BAE Systems then performed the manual LAS classification, breakline collection, and production of the bare-earth DEMs. Dewberry was responsible for the final quality review of all project deliverables, including vertical accuracy testing. Dewberry prepared the final project reports and metadata. Dewberry's IES offices completed ground surveying for the project and delivered surveyed checkpoints. Their task was to acquire surveyed checkpoints for the project to use in independent testing of the vertical accuracy of the Lidar-derived surface model. Note that a separate Survey Report was created for this portion of the project. The Atlantic Group completed Lidar data acquisition and data calibration for 1,071 square miles covering the project area.

10   2010 / 2011 Shenandoah Valley Lidar - sv1area
 
Description
The entire survey area for northern Shenandoah valley encompasses 714 square miles. The Shenandoah Lidar project, ordered by the USGS, provides precise elevations acquired by the Optech 3100 serial number 07SEN203 airborne Lidar sensor. The Lidar point cloud was acquired at a nominal point spacing of 1.0 meter. High accuracy multiple return Lidar data, both raw and separated into several classes, are provided, along with hydro flattening breaklines and bare earth DEM tiles. The classified point cloud and bare earth DEM data has been tiled into 1500 meter by 1500 meter tiles, stored in LAS format version 1.2 (point format 1), and Lidar returns coded into 6 separate ASPRS classes. The Lidar data and derivative products produced are in compliance with the U.S. Geological Survey National Geospatial Program Guidelines and Base Specifications, Version 13-ILMF 2010. The Lidar data were acquired by Northrop Grumman, 3001 Operating Unit (OU), which were flown over nine missions between March 01, 2011 and March 09, 2011. The Northrop Grumman 3001 OU implemented a variety of quality assurance and quality control procedures throughout the processing phases in order to provide a product that meets or exceeds the requirements specified in the USGS contract G10PD02496. 50-100 percent Coverage: Berkeley (WV), Warren, Frederick, Rockingham, Augusta.
Disclaimer: This Lidar data set has met vertical accuracy requirements and has been validated to be an accurate representation of the ground at the time of survey.

11   2010 Eastern Shore Lidar - Northampton and Accomack Counties, VA
 
Description
The Virginia Geographic Information Network contracted with Sanborn to provide Lidar mapping services for the Accomack, VA area in spring 2010. Utilizing multi-return systems, Light Detection and Ranging (Lidar) data in the form of 3-dimensional positions of a dense set of mass points was collected for approximately 1090 square miles. All systems consist of geodetic GPS positioning, orientation derived from high-end inertial sensors and high-accurate lasers. The sensor is attached to the aircraft's underside and emits rapid pulses of light that are used to determine distances between the plane and terrain below.

13   Lidar for Loudoun County, VA
 
Description
The purpose of this Lidar data was to produce high accuracy 3D elevation products, including tiled Lidar in LAS 1.2 format, 3D breaklines, and a 1 m cell size hydro flattened Digital Elevation Models (DEM). This Lidar was produced for the Loudoun 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 694 tiles (1500 m x 1500 m) that cover the this deliverable.

18   B4 Project (San Andreas & San Jacinto Fault) Lidar Imagery
 
Description
Project B4 is an NSF project led by OSU and USGS scientists, and supported by NCALM and UNAVCO, that completed an Airborne Laser Swath Mapping (ALSM) survey of ~ 1,000 km of the southern San Andreas Fault and San Jacinto Fault systems in mid-2005. The purpose is to obtain pre-earthquake imagery necessary to determine near-field ground deformation after a future large event (hence the name B4), and to support tectonic and paleoseismic research. This particular data set has been gridded at ~1 meter resolution.
