Collection Overview:
Lidar dataset collected for the five islands comprising Channel Islands National Park. This includes all of the islands of San Miguel, Santa Rosa, Anacapa, Santa Barbara, and Santa Cruz. The project totals about 288 square miles (747 square kilometers). Elevation data were delivered in 2,000m x 2,000m tiles with 280 tiles produced. Deliverables include LAS 1.2 files (classified and raw), digital elevation model, digital surface model, control data, and metadata. Full waveform data were also collected over the entire project area.
Data were collected using a Riegl LMS-Q560 laser scanner flown from a helicopter. Helicopters were also used to establish ground control on all five islands. Personnel from National Park Service and The Natural Conservancy (which owns most of Santa Cruz Island) accompanied the survey team to ensure minimal impact to habitat. To assist with positional accuracy, continuously operating reference stations (CORS) on each island were modified by UNAVCO from a 15 second to a one second sampling rate during the collection period. Nominal single swath point density was three points per square meter (seven points with 50% overlap).
