A Comparison of Multispectral and Hyperspectral Re-mote-sensing data from coincident flights of Crewed and Un-crewed Aircraft

This dataset archive contains the full set of imagery, calibration data, and derived products used to evaluate the performance of two low-cost UAS multispectral sensors (MicaSense RedEdge and SlantRange 3p) relative to the NEON Imaging Spectrometer (NIS). The data include radiometrically calibrated reflectance measurements, field-based tarp calibration observations, and spectrally resampled NIS imagery used as a reference standard, along with corresponding NDVI products for each sensor platform. These datasets support analysis of systematic reflectance and vegetation index biases across multiple land cover types, providing a basis for cross-platform comparison and validation. The archive enables reproducibility of results and facilitates further investigation into sensor-specific limitations, calibration approaches, and the integration of UAS multispectral data with airborne hyperspectral observations for ecological and agricultural remote sensing applications.
