This task order is for planning, acquisition, processing, and derivative products of lidar data to be collected for the Valdez area. This project is located in Valdez-Cordova county, Alaska for Starr. Specifications listed below are based on FEMA Procedure Memorandum No. 61 Standards for LiDAR and Other High Quality Digital Topography. LiDAR acquisition of Valdez, consisted of 25 square miles. The 25 square miles was captured to the "Highest" vertical accuracy requirement. This collection specification is the equivalent of a 2 foot contour accuracy, and was collected with a nominal pulse spacing of 8 points per meter. AeroMetric, Inc. employed an Optech ALTM Gemini LIDAR system, as well as a our Leica ALS70 in the acquisition of this LIDAR data. The airborne GPS and IMU data were processed immediately following each mission. In addition, a sample of the LIDAR data was post-processed at the completion of each mission and the data was reviewed to ensure planned data quality and coverage. The NOAA Office for Coastal Management (OCM) downloaded this lidar data from the AK DGGS site (https://elevation.alaska.gov/) and processed the data to be available on the Digital Coast Data Access Viewer (DAV). This data set is an LAZ (compressed LAS) format file containing LIDAR point cloud data.
