Information to be Derived: Assessment of the field capability of the OceanInsight spectrometer in terms of accuracy compared to the industry standard and ease of use in the field.

Summary of Activity and Data Gathered: Data was collected over three days in October 2021 (10/6, 10/7, and 10/8), which included aerial UAS true color and multispectral imagery, ground-spectroradiometer reflectance data, and RTK GPS data. Ground-based spectral reflectance data and the UAS imagery were collected on the 6th and 7th to support the primary mission: a comparative study of the OceanInsight mini HDX and ASD field spectroradiometers. A PVC quadrat was carried out into the field and served as the ROI for vegetation samples that were measured with the spectroradiometers. Three collections were taken of each vegetation sample with each instrument. The RTK GPS was used to survey the center and four corners of the quadrat. The vegetation was described, photographed, and height measured and recorded in a field notebook. The RTK GPS was also used to survey aeropoints and vinyl control points for UAS imagery processing. On the 8th, time permitting, an additional survey was conducted with the RTK GPS in order to collect data for a thematic classification analysis in pairing with the UAS imagery from the previous days. In addition to the aeropoints and ground control points, 100+ surface classes of interest were surveyed, photographed, and height measured and recorded in a field notebook.
