Abstract:

Unmanned Aerial Systems (UAS) imagery was collected during a 1-week mission to the western Mississippi Sound to calibrate and validate remote sensing algorithms for estimating water quality parameters from UAS data. This dataset includes imagery, average radiance values, and calibration images. Similar data collected in 2022 are available in related dataset M2.x936.000:0014 (https://doi.org/10.7266/9XVJNRF5).

Purpose:

To develop remote sensing algorithms.

Data Parameters and Units:

Brightness Values

Methods:

A DJI Inspire-2 Uncrewed Aerial Vehicle with a Micasense RedEdge MX sensor onboard was flown at 400 feet altitude to collect these data. Image processing followed the process provided by MicaSense at GitHub - micasense/imageprocessing: MicaSense RedEdge and Altum image processing tutorials. The steps included: 1. Remove dark pixel offset (imager noise) 2. Correct for vignetting effects 3. Correct for row gradient 4. Normalize by exposure and gain settings 5. Convert to radiance values 6. Further, convert to reflectance by using panel values 7. Remove lens distortion effects 8. Orthorectify image by using various GPS/IMU sources (hyperspectral IMU and UAS IMU values)

Instruments:

MicaSense RedEdge MX, DJI Inspire-2 UAV; 5.5mm lens, f2.8, ISO 100, resolution 300 x 300, 16 bits
