Dataset Identification:
- In October 2012, WSI (Watershed Sciences, Inc.) was contracted by the Puget Sound LiDARConsortium (PSLC) to collect Light Detection and Ranging (LiDAR) data for the EntiatRiver site in central Washington. The area is adjacent to several other LiDAR projectscollected in the greater Wenatchee area since 2008. Data were collected to aid inassessing the topographic and geophysical properties of the study area to supportfault line and geologic instability within the area. The Entiat site covers 67,067 acres,collected June 23, 26, 28, 29 and 30, 2013.

- 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be aware that temporal changes may have occurred since this data set was collected and some parts of this data may no longer represent actual surface conditions.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.

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 ofthe 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.Not reported, assumed as 1.0 m. Laser horizontal errors are a function of flight altitudeabove ground (i.e., +/- 1/3000th AGL flight altitude). Relative errors for the position mustbe less than 1.5 cm horizontal and 2.0 cm vertical in order to be accepted.
- name Of Measure Horizontal Positional Accuracy
- measure Description See Lidar report.

-
- result value 1.0

-
- name Of Measure Vertical Positional Accuracy Report
- evaluation Method Description Upon the LiDAR data arrival to the office, WSI processing staff initiates a suite ofautomated and manual techniques to process the data into the requested deliverables.Processing tasks include GPS control computations, smoothed best estimate trajectory(SBET) calculations, kinematic corrections, calculation of laser point position,calibration for optimal relative and absolute accuracy, and classification ofground and non-ground points.
- name Of Measure Vertical Positional Accuracy
- measure Description Vertical absolute accuracy was primarily assessedfrom RTK ground check point (GCP) data collected on open, bare earth surfaces with levelslope (<20 degrees). Fundamental Vertical Accuracy (FVA) reporting is designed to meet guidelinespresented in the FGDC National Standard for Spatial Data Accuracy3. FVA compares known RTKground survey check points to the triangulated ground surface generated by the LiDAR points.FVA is a measure of the accuracy of LiDAR point data in open areas where the LiDAR system hasa ?very high probability? of measuring the ground surface and is evaluated at the 95%confidence interval (1.96 sigma) calculated 0.152 ft (4.6 cm).
- Quantitative Result
-
- result value 0.046
- value Units
-
- evaluation Method Description LiDAR data has been collected and processed for all areas within the project study area.
- measure Description The accuracy of the LiDAR data collection can be described in terms of absolute accuracy (the consistency ofthe data with external data sources) and relative accuracy (the consistency of the dataset with itself). SeeAppendix A in the lidar report for further information on sources of error and operational measures used toimprove relative accuracy.
