Detection of crop properties by means of hyperspectral remote sensing from a micro UAV

Martin Rehak, Yosef Akhtman, Dragos Constantin

Aerial hyperspectral remote sensing technologies provide effective methods for the exploration and study of plant and crop properties. In this study a custom made hexacopter was equipped with a small scale hyperspectral imaging (HSI) camera capable of meas ...

Modeling Soil–Plant Dynamics: Assessing Simulation Accuracy by Comparison with Spatially Distributed Crop Yield Measurements

Sara Bonetti

Coupling hydrological models with plant physiology is crucial to capture the feedback mechanisms occurring within the soil–plant–atmosphere continuum. However, the ability of such models to describe the spatial variability of plant responses to different e ...

Fixed-wing Micro Aerial Vehicle for Accurate Corridor Mapping

Jan Skaloud, Martin Rehak

In this study we present a Micro Aerial Vehicle (MAV) equipped with precise position and attitude sensors that together with a pre-calibrated camera enables accurate corridor mapping. The design of the platform is based on widely available model components ...

Change in snow distribution patterns over an Antarctic ice floe following a snow storm event

Michael Lehning, Katherine Colby Leonard, Ernesto Trujillo Gomez

Sea ice, snow and atmosphere interactions are major drivers of the spatial distribution of snow over sea ice in polar regions. Here, we quantify changes caused by a snow storm in the spatial distribution of snow over an Antarctic ice floe at resolutions of ...

Mapping with MAV: Experimental Study on the Contribution of Absolute and Relative Aerial Position Control

Jan Skaloud, Martin Rehak

This study highlights the benefit of precise aerial position control in the context of mapping using frame-based imagery taken by small UAVs. We execute several flights with a custom Micro Aerial Vehicle (MAV) octocopter over a small calibration field equi ...

A Large Eddy Simulation to determine the effect of trees on wind and turbulence over a suburban surface

Marc Parlange, Marco Giovanni Giometto, Andreas Christen

A proper modeling of flow and turbulence within and over urban canopies is key to properly predict air pollution and dispersion in cities. Trees are an integral part of the urban landscape. In many suburban neighborhoods, tree cover is 10 to 30% and trees ...

Improved snowmelt simulations with a canopy model forced with photo-derived direct beam canopy transmissivity

Michael Lehning

The predictive capacity of a physically based snow model to simulate point-scale, subcanopy snowmelt dynamics is evaluated in a mixed conifer forest, southern Sierra Nevada, California. Three model scenarios each providing varying levels of canopy structur ...
