Radiometric calibration and optical analysis of in-flight satellite-based imagers is generally achieved using on-board systems and by vicarious observation of celestial objects and earth-based geographical locations. These methods have been the standard for most instruments currently deployed; however, on-board systems are costly and existing vicarious means have known drawbacks which impact uncertainty in final measurements.

This research project seeks to address the challenging problem of sharpening remotely sensed hyperspectral imagery with higher resolution multispectral or panchromatic imagery, with a focus on maintaining the radiometric accuracy of the resulting sharpened imagery. Traditional spectral sharpening methods focus on producing results with visually accurate color reproduction, without regard for overall radiometric accuracy. This is done primarily to support exploitation through visual interpretation. However, hyperspectral imagery (HSI) is not exploited through purely visual means.

Prescribed fire is used as a management tool for a number of reasons- fuel reduction for mitigating the impact of wild fires, habitat improvement for game and other species, and as a successional management tool for forests like the coastal plains barrens, among others. Current predictive models used to simulate fire behavior during low-intensity prescribed fires (and low-intensity wildfires) are empirically-based, simplistic, and fail to adequately capture variability in fuel characteristics and interactions with important meteorological variables. We are undertaking, along with collaborators from the USDA Forest Service - Northern Research Station, -Pacific Northwest Research Station, University of Edinburgh and the Worcester Polytechnic Institute, to use a suite of measurements at the fuel particle, fuel bed, field plot and stand scales (or levels) to quantify how variability in fuel characteristics and key meteorological factors interact to drive fire behavior during low intensity prescribed burns.

The objective of this research is to assess the feasibility of using, in order of priority, remotely captured thermal infrared, LiDAR, hyperspectral, and RGB imagery to detect and classify duck nests in the Pothole Prairie region, North Dakota. Natural resources such as ducks and wildlife are vital to North Dakota, bringing in more than 21 million visitors and 3 billion dollars in revenue annually. 50-80% of all North American ducks are born in the Prairie Pothole Region which ranges from Canada down through Montana, the Dakotas, Minnesota, and finally, Iowa. The Prairie Pothole Region is shrinking, losing approximately 50,000 acres every year.

Lidar remote sensing has shown high accuracy/precision for quantification of forest biophysical parameters needed for ecological management. Although the significant effect of Bidirectional Scattering Distribution Functions (BSDF) on remote sensing of vegetation is well known, current forest metrics derived from lidar data seldom take leaf BSDF into account. Despite the importance of BSDF effects, leaf directional scattering measurements are almost nonexistent, particularly for transmission. Previous studies have been limited in spectrum, lacked models to capture all angles beyond measurements, and did not adequately incorporate transmission scattering. Furthermore, many current remote sensing simulations, which are vital to our understanding of lidar data, assume leaves with Lambertian reflectance, opaque leaves, or apply purely specular or Lambertian transmission. The accuracy of these assumptions and the effect on simulation results are currently unknown. This study captured deciduous broadleaf BSDFs from the visible through shortwave infrared spectral regions, accurately modeled the BSDF for extension to any illumination angle, viewing zenith or azimuthal angle.

The two objectives of the research – yield modelling and harvest scheduling- have undergone extensive research over the past year. An RIT-based greenhouse study during winter and spring of 2019 resulted in insightful results regarding both yield and harvest of snap-bean, as a proxy crop. PhD student Amir Hassanzadeh collected high-temporal frequency spectroradiometer data (400-2500 nm) for 48 snap bean plants over the course of a full growing season; this took place using a controlled-environment set-up, thus enabling collection of spectra under a best-case scenario (figure to the right). Our results for the harvest maturity objective show that one could classify based on spectra, as well as spectral and physical attributes between ready-to-harvest and not-ready-to-harvest plants with 76% and 80% accuracy, respectively. For the yield modelling objective, our results from partial least square regression depicts that the best time for yield prediction is 20 days prior to harvest. We aim to investigate harvest modelling and yield scheduling of the snap bean crop of six different cultivars located at a research farm, in Geneva, N.Y.
