Summary

The purpose of this field data collection was to test and compare the OceanInsight HDX Mini Spectrometer as an accessible alternative against the more expensive ASD Fieldspec for collecting ground-based hyperspectral reflectance profiles for landcover analysis. The data collection took place in Dog Head Marsh and South Cape Beach within the Waquoit Bay National Estuarine Research Reserve (WBNERR). The hyperspectral profiles were collected side-by-side with both field-spectrometers using comparable sensor collection settings for various ground cover samples. The terrain and vegetation type of these sample were described as well as surveyed using Real Time Kinematic Global Positioning System (RTK-GPS). This data was collected within [...]

Purpose

Hyperspectral reflectance spectra (spectral profiles) for various ground cover types were collected by two separate spectroradiometer instruments to compare in order to evaluate the lower-cost instrument as an affordable alternative. These profiles can also be used to validate multispectral imagery as well as in landcover classification workflows.
