Processing and Assessment of Spectrometric, Stereoscopic Imagery Collected Using a Lightweight UAV Spectral Camera for Precision Agriculture

2013

Imaging using lightweight, unmanned airborne vehicles (UAVs) is one of the most rapidly developing fields in remote sensing technology. The new, tunable, Fabry-Perot interferometer-based (FPI) spectral camera, which weighs less than 700 g, makes it possible to collect spectrometric image blocks with stereoscopic overlaps using light-weight UAV platforms. This new technology is highly relevant, because it opens up new possibilities for measuring and monitoring the environment, which is becoming increasingly important for many environmental challenges. Our objectives were to investigate the processing and use of this new type of image data in precision agriculture. We developed the entire pro…

Spectral imaging from UAVs under varying illumination conditions

2013

Abstract. Rapidly developing unmanned aerial vehicles (UAV) have provided the remote sensing community with a new rapidly deployable tool for small area monitoring. The progress of small payload UAVs has introduced greater demand for light weight aerial payloads. For applications requiring aerial images, a simple consumer camera provides acceptable data. For applications requiring more detailed spectral information about the surface, a new Fabry-Perot interferometer based spectral imaging technology has been developed. This new technology produces tens of successive images of the scene at different wavelength bands in very short time. These images can be assembled in spectral data cubes wit…

Misura e Modellazione degli Scambi Idrici nel Sistema Continuo SPA e approfondimenti sulle Funzioni di Stress Idrico: Applicazione alla coltura dell’…

2010

Gli effetti negativi dovuti ai periodi di aridità che caratterizzano i Paesi del bacino del Mediterraneo (Rebetez et al. 2006) determinano nel suolo una ridotta disponibilità di acqua per le piante e quindi l’insorgenza inevitabile di una forma importante di stress abiotico (Nielsen et al., 1996). In particolare, nel bacino del Mediterraneo l'aridità ambientale viene ancor più accentuata da fattori climatici poiché, in corrispondenza del periodo estivo, alle scarse o assenti precipitazioni sono associate elevate temperature che si traducono in un aumento della domanda evapotraspirativa dell’atmosfera. Tali effetti sono più marcati nelle regioni semiaride del bacino del Mediterraneo e più in…

SMOS REFLEX 2003: L-band emissivity characterization of vineyards

2005

The goal of the Soil Moisture and Ocean Salinity mission over land is to infer surface soil moisture from multiangular L-band radiometric measurements. As the canopy affects the microwave emission of land, it is necessary to characterize different vegetation layers. This paper presents the Reference Pixel L-Band Experiment (REFLEX), carried out in June-July 2003 at the Vale/spl grave/ncia Anchor Station, Spain, to study the effects of grapevines on the soil emission and on the soil moisture retrieval. A wide range of soil moisture (SM), from saturated to completely dry soil, was measured with the Universitat Polite/spl grave/cnica de Catalunya's L-band Automatic Radiometer (LAURA). Concurre…

The potential of γ-ray spectroscopy for soil proximal survey in clayey soils Le potentiel de la spectroscopie a rayons-γ lors de l’echantillonnage pe…

2013

La spettroscopia di raggi-γ misura la distribuzione e l’intensità della radiazione gamma emessa naturalmente dai suoli o dalle rocce. I radionuclidi più importanti nel suolo come fonte di raggi gamma sono: 40K, 232Th, 238U ed 137Cs, quest’ultimo di origine artificiale, principalmente legato all’esplosione di Chernobyl o ad inquinamenti radioattivi. La distribuzione e la quantità di questi radionuclidi è strettamente dipendente dalla mineralogia del parent material e dalla capacità di scambio cationico del suolo. Scopo di questo lavoro è quello di mostrare le potenzialità di un rilevamento prossimale con spettroscopia di raggi-γ in campi sperimentali con suoli argillosi della Sicilia occiden…
