This Lidar was collected for the National Park Service because they require a high-resolution digital elevation model to serve as a base layer for further inventory and monitoring of Sunset Crater Volcano's unique resources. The objective of this procurement was to acquire a high-resolution bare-earth digital elevation models (DEM) of SUCR and adjacent areas around the park. The accuracy of the final DEM is an interval ranging from 0.15 meter to 0.50 meter.
The lidar survey was accomplished with a Leica ALS50 Phase II mounted in a Cessna Caravan with an average yield pulse density of 8 pulses/m2 over the Sunset Crater Lidar terrain. Project Site: Sunset Crater National Monument which is located in Coconino County Arizona; Acres of Lidar collected 10,233; Date of Acquisition 09/16/2012; Lidar Format LAS v 1.2.
