PROJECT OBJECTIVE:
Capture time series, aerial imagery of dye tracer experiments at Fernan Lake.

LOCATION:
Fernan Lake, Idaho

Approx. Bounds:  
47.67783, -116.71158
47.67571, -116.71158
47.67571, -116.7079
47.67783, -116.7079

DATES:
August 2, 2018  (approximate timespan: 6:00 AM - 9:35 AM, Pacific)
August 30, 2018 (approximate timespan: 1:00 PM - 6:35 PM, Pacific)

METHODS:
Aerial (RGB) imagery of dye tracer dispersion was captured using a Phantom 4 Pro drone.  Flight programming was done with Pix4D.

Camera Angle:  90%
Altitude: 140 ft
Overlap (Aug 2):  75% - 75% 
Overlap (Aug 30): 77% - 77% 
Flight duration:  7.5 - 10.5 min (each flight)

Aug 2, 2018:  
19 sequential flights were conducted (120 to 209 images captured per flight) over the same approximate area. Flights were repeated approximately every 10-15 minutes in order to capture time-series distribution of dye tracer.

Aug 30, 2018:  
20 sequential flights were conducted (122 to 159 images per flight) over the same approximate area. Flights were repeated approximately every 10-15 minutes in order to capture time-series distribution of dye tracer.

Images from each flight were stitched together using WebODM software, resulting in 19 composite images from Aug 2, 2018, and 20 composite images from Aug 30, 2018.  The resulting composite images can be viewed in sequence for a given day to observe the dispersion of dye tracer over time.
