The requested survey area is located approximately 8 km west and north of Flagstaff, AZ within the Coconino National Forest. The polygon encloses approximately 89.7 km2.Publications associated with this dataset can be found at NCALM's Data Tracking Center Dataset Acknowledgement: Lidar data acquisition and processing completed by the National Center for Airborne Laser Mapping (NCALM).
