May 2002 Lidar Point Data of Southern California Coastline: Dana Point to Point La Jolla

Description

This data set contains lidar point data from a strip of Southern California coastline (including water, beach, cliffs, and top of cliffs) from Dana Point to Point La Jolla. The data set was created by combining data collected using an Optech Inc. Airborne Laser Terrain Mapper (ALTM) 1225 in combination with geodetic quality Global Positioning System (GPS) airborne and ground-based receivers. The Bureau of Economic Geology, the University of Texas at Austin owns and operates an ALTM 1225 system (serial number 99d118). The system is installed in a single engine Cessna 206 (tail number N4589U) owned and operated by the Texas State Aircraft Pooling Board. The lidar data set described by this document was collected at low tide on 22 May 2002 (14202) between 18:20 and 21:39 UTC (actual data collection). Conditions on that day were light clouds along the shoreline as well as offshore. 99d118 instrument settings for this flight were; laser pulse rate: 25kHz, scanner rate: 26Hz (28Hz for calibration target), scan angle: +/-20deg, beam divergence: narrow, altitude: 680-780m AGL for first half of flight and 900-950 for second half of flight, and ground speed: 83-125kts. Two GPS base stations (Scripps pier and San Onofre Power Plant) were operating during the survey. The survey included 3 shoreline passes between Dana Point and Point La Jolla as well as one offshore pass along the 20m isobath. Data represented is all points including terrain, vegetation, and structures. This data also contains returns from the water surface. No processing has been done to remove returns from terrain, vegetation, structures or water surfaces.
