2011 USGS NOAA USACE Lidar: Matanuska-Susitna Borough, AK

Description

The Matanuska Susitna Borough LiDAR/Imagery Project covers 3680 sq/mi of the Matanuska-Susitna Borough in Alaska. Project parnters and funding sources include: Coastal Impact Assistance Program, Alaska Industrial Development and Export Authority, Alaska Energy Authority, United States Geological Survey, Matanuska Susitna Borough, United States Army Corps of Engineers, United States Fish and Wildlife Service, The Nature Conservancy, National Oceanic and Atmospheric Administration, Mat-Su Salmon Partnership, and Alaska Pacific University. This dataset was originally in LAS 1.2 format with a non-standard class table. The format and the class table has been changed. Details are in the processing steps. The following are the collection parameters and equipment used to create these data sets. The Leica sensor was used for flights in the northern half of the Core Area. All other flights were flown with Optech sensors. Aircraft: Cessna 310(N7516Q), Piper Navajos (N6GR,T73TM and 812TB), Beechcraft KingAir (N898WW) Lidar Systems: Optech ALTM Gemini (03SEN145 and 07SEN201) and Leica ALS 70 Approximate Collection Altitude (Above Mean Terrain): Optech--1400 meters, Leica--2200 meters Ground Speed: Optech--150 kts, Leica--160 kts Pulse Rate Frequency: Optech--70 kHz, Leica--163.6 kHz Mirror Scan Frequency: Optech--40 Hz, Leica--41 Hz Scan Angle (+/-): Optech--17 degrees, Leica--16 Degrees Beam Divergence: Narrow (0.3 mrad) Accuracy statements are based on areas of moderate terrain, with points classified as ground. Diminished accuracies are to be expected in areas of extreme terrain and dense vegetation. The accuracy of each point is expected to meet the vertical accuracy standard, derived products may be less accurate in areas of extreme terrain and dense vegetation due to a lesser number of points defining the ground in these areas. Classified data sets such as this one may have varying posting due to some pulses not reaching the ground. Original contact information: Contact Name: Lidar Manager Contact Org: Aerometric, Inc.
