Text files: These data are text files of GNSS survey points collected along a trace of the West Napa Fault Zone near Ehlers Lane north of St. Helena, California. Data were collected to aid in paleoseismic investigation of the suspected fault strand and to characterize local geomorphology. Data were collected on March 31, and August 1, 2017 using a Leica Viva GS15 survey-grade GNSS receiver. The data are delivered as positions in the NAD83 UTM zone 10N coordinate system with orthometric heights according to Geoid 12B. LAZ files: These data are point clouds from terrestrial lidar data collected along a trace of the West Napa Fault Zone near Ehlers Lane north of St. Helena, California. Data were collected to aid in...
