Dataset Identification:
- Terrapoint collected Light Detection and Ranging (LiDAR) data for the Lewis County project of 2005. The project site covered approximately 223 square miles, divided into two blocks: southern block 213 Square Miles, northern block 10 Square Miles. The field data collection took place from December 11th, 2004 to January 30th, 2005. LIDAR data was collected on 12/11/2004, 12/12/2004, 12/15/2004, 1/20/2005, 1/21/2005, 1/24/2005 and 1/30/2005. The control network and check point surveys were established from December 11th to December 23rd, 2004. 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.

- Use limitation statement:
- These data depict the elevations at the time of the survey and are only accurate for that time. Users should be aware that temporal changes may have occurred since this data set was collected and some parts of this data may no longer represent actual surface conditions. Users should not use this data for critical applications without a full awareness of its limitations. Any conclusions drawn from analysis of this information are not the responsibility of NOAA or any of its partners. These data are NOT to be used for navigational purposes.

- Use Limitation
- While every effort has been made to ensure that these data are accurate and reliable within the limits of the current state of the art, NOAA cannot assume liability for any damages caused by any errors or omissions in the data, nor as a result of the failure of the data to function on a particular system. NOAA makes no warranty, expressed or implied, nor does the fact of distribution constitute such a warranty.

Data quality information
Scope of quality information
- name Of Measure Horizontal Positional Accuracy Report
- evaluation Method Description Horizontal positional accuracy for LiDAR is dependent upon the quality of the GPS/INS solution, sensor calibration and ground conditions at the time of data capture. The standard system results for horizontal accuracy are less than 1 meter.
- name Of Measure Horizontal Positional Accuracy
- measure Description Reporting highest reported values with uncertainty of likelihood of less than 0.60 m horizontal accuracy values. 20 ? 60 centimeters on all but extremely hilly terrain.
- Quantitative Result
-
- result value 0.60
- value Units
-
- name Of Measure Vertical Positional Accuracy Report
- evaluation Method Description Laser point returns were optimized for internal consistency based on independent data from the LiDAR system, IMU, and aircraft. Noise points (e.g. pits and birds) were filtered from the data based on known elevation ranges. This data was then compared to 960 real time kinematic ground survey points collected to verify the vertical and horizontal accuracies of the data set.
- name Of Measure Vertical Positional Accuracy
- measure Description Averaged to 25 cm. 15-15 centimeters on Hard Surfaces (roads and buildings), 15-25 centimeters on Soft/Vegetated Surfaces (flat to rolling terrain), 25-40 centimeters on Soft/Vegetated Surfaces (hilly terrain)
- Quantitative Result
-
- result value 0.25
- value Units
-
- evaluation Method Description LiDAR data has been collected and processed for all areas within the project study area.
- measure Description LiDAR flight lines have been examined to ensure that there was at least 50% sidelap, there are no gaps between flightlines, and overlapping flightlines have consistent elevation values. Shaded relief images have been visually inspected for data errors such as pits, border artifacts, gaps, and shifting. The data was examined at a 1:3500 scale.
