Gila River at Interstate 10 - GPS Survey of Control Data for LiDAR Model 2020

The dataset contains GPS survey data of ground control points deployed for aerial LiDAR data collection. The targets were deployed and surveyed on 8/12/2020 and the LiDAR flight was conducted on the morning of 8/13/2020. The control points were surveyed using Leica GS14 RTK GPS equipment, S/N rover-2806883, using the Real Time Network, Leica Smartnet, to determine absolute posi

Gravity data from the Truxton area, northwestern Arizona, tabular format

This dataset represents the network-adjusted results of relative- and absolute-gravity surveys. Relative-gravity surveys were carried out using a ZLS Coporation Burris relative-gravity meter. The effect of solid Earth tides and ocean loading were removed from the data. Instrument drift was removed by evaluating gravity change during repeated measurements at one or more base stations, or...
