Project: Holy Fire Headwater Sediment Dynamics, Santa Ana Mts, CA (U-075)
Field Start Date: Oct. 25, 2018
Field End Date: Oct. 30, 2018
Field Engineer: James Guilinger
Site Notes: Steep hillslopes (>32 degrees) and dusty conditions. A few site visits during TLS scans were far too windy to deploy the UAV and other logistical constraints led to some differences in timing of datasets, but overall SfM and UAV datasets bracketed same major storm cycles. Permanent rebar monuments (sixteen for TLS and SfM, with additional seven for SfM, though only six was determined to be an outlier and excluded) sunk into bedrock or regolith were established and dimpled ends were occupied using a robotic total station (GeoMax Zoom80) into a local cartesian grid. 10cm diameter permanent retroreflectors (Figure 1) machined by UCR Machine Shop to the exact specifications after D. Finnegan of USACE Cold Regions Lab (details here: https://kb.unavco.org/kb/article.php?id=794) were affixed to 16 of these using steel weld epoxy such that the primitive point was fixed at the dimpled center (Fig 2) . The remainder had tennis balls affixed to them. This ground control was transformed into a geodetic frame (NAD83(2011) UTM Zone 11N) following re-occupation of totaled base-station and back-sight via static GNSS (Zephyr Geodetic antennae and Net RS receivers).

Other Equipment: DJI Mavic Pro 1 with stock camera. iPad and remote controller used for flight control and live camera feed
