These are terrestrial laser scanner datasets collected in forested areas west of Flagstaff, Arizona in 2015 and 2016. For each of the two scanners, six treatment areas were scanned, with four of them overlapping one another (Figure 1). These data are composed of individual scans referenced to one another using reflective targets, and geolocated using differentially corrected GPS and RTK locations of scan locations (Figure 3). There were overall large differences in point density among the two scanners (Figure 2).

These data were compiled for a study examining the use of terrestrial laser scanners in ponderosa pine forests of Northern Arizona. The data was collected by two instruments: a Riegl VZ-1000 and a unit built for this project, called the Autonomous Terrestrial Laser Scanner (FIgure 1). This data served two purposes, to evaluate the relative rates of point density decay of terrestrial laser scanner data in ponderosa pine forests of northern Arizona (Figure 5), and to evaluate the relative accuracies of estimated forest structure attributes, including tree diameter, height, height to canopy, and overall tree density (Figure 6 and Figure 7).
