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 also part of this collection and covers approximately 6,519 acres but is not included in this data set because it was collected using QL1 criteria. A link to the metadata record for the QL1 survey area is provided in the Related Items field at the end of this metadata record. Dataset Description: RAW flight line swaths were processed to create classified LAS 1.4 files projected in UTM Zones 10 and 11 and delineated in 1,000m x 1,000m tiles. (Please note the following tiles do not exist as no points fall within their boundaries due their small size and/or the fact they fall completely over water: 10TGR1465, 10TER6244) Each LAS file contains lidar point information, which has been calibrated, controlled, and classified. Additional derived products include intensity images, hydro-flattened DEMs, 3D breaklines of rivers and lakes, and bridges within the study area. Ground Conditions: Ground condition was free of snow. Acquisition below aircraft free of smoke, fog and cloud cover. Ground Control Points were acquired and calibrated by Quantum Spatial, Inc.
