Project Type: Specific C/A

Start Date: Jun 01, 2004
End Date: Sep 30, 2006

Objective:
The objectives of this cooperative research project are to explore the application of remote sensing systems (visible, thermal, etc.) and develop novel analytical techniques for (1) determining crop growth stage, (2) detecting the onset of yield-limiting stress (e.g. water stress), and (3) determining potential insect infestation based on canopy development and crop physiological status.

Approach:
Hyperspectral and multispectral imagery in the visible, near-infrared and thermal bands will be collected using ground-based and aerial platforms from crop canopies displaying various characteristics as a result of changes in management. Novel analytical tools, such as Fourier transforms and principle component analysis, will be explored to analyze the data for maximal information retrieval. Synthetic spectra will be generated from individual components of the canopy reflectance and emission spectra for delineation of importance of each to the overall spectrum, and for comparison with aerial images. Remote imagery data will be corroborated with extensive biophysical, edaphic, physiological and entomological information of the crop canopy. Changes in leaf and canopy images will be correlated to specific physiological changes. Detection methodologies that reliably and accurately detect the onset of crop water stress can then be incorporated into decision support tools for irrigation management.
