  "description": "In August 2017, Quantum Spatial (QSI) was contracted by the United States Geological Survey (USGS) to collect Light Detection and Ranging (LiDAR) data for the Olympic Peninsula 3DEP QL1 LiDAR project site in the state of Washington. The Olympic Peninsula 3DEP LiDAR project area covers approximately 3.4 million acres ( 5,352 square miles) in northwestern Washington split into four areas. The target point density for each study area is  \u22658.0 points/m^2 (0.74 points/ft^2).\n\t\t\t\nGround Conditions: Acquisition below aircraft free of smoke, fog and cloud cover. Ground Control Points were acquired and calibrated by Quantum Spatial, Inc.\n\t\t\t\nTidal Conditions: The Olympic Peninsula project area is bounded by miles of coastline and includes many tidally influenced lakes and river deltas.  Since the project was acquired over many months, it is expected that there is data captured at varying tide levels which lends issues to the hydroflattening process.  To accommodate these tidal and temporal differences, it is not uncommon to \"stair-step\" the flattened water surface to most accurately reflect the different missions in the project while capturing as much ground as permitted.  Please reference section C.1.c.(ii).(d) of the task order and the Hydroflattening section of the USGS LiDAR Base Specification, V. 1.2 for more information. Task Name: WA Olympic Peninsula LiDAR 2017 B17, USGS Contract: G16PC00016, Task Order: G17PD00827",
