NON TECHNICAL SUMMARY: OBJECTIVES: Investigate development and use of a cannabis growth simulation model as a tool to aid with cannabiis detection. Define hyperspectral reflectance signatures of cannabis for dection of illicit cannabis cultivation.
APPROACH: We will attempt to adapt and existing growth model for another crop to simulate cannabis production. Measurements will be taken under controlled environmental settings to develop coefficients for the fundamental relationships. We will determine spectral features of cannabis suitable for use with airborne remote sensing system. [FONT=arial,helvetica]

4. What were the most significant accomplishments this past year? This project is a reimbursable agreement with the Office of National Drug Control Policy with oversight by the National Guard Counter Drug Office to provide assistance in the completion of the objectives associated with the parent project CRIS 1265-12660-005-00D titled Spectral and Spatial Measurements and Modeling to Improve Nutrient Management and Environmental Quality. The project seeks to develop remote sensing technologies and a plant growth simulation model for detecting illegal marijuana cultivation. The Hydrology and Remote Sensing Lab conducted investigations of marijuana leaf spectral reflectance and showed that its unique blue-green reflectance reported by law enforcement aerial spotters is the result of green reflectance from internal chlorophyll-bearing leaf cells plus a blue specular reflectance from microscopic structures on the surface of the leaf. Further investigation of the specular feature showed that while it is not unique to marijuana, it is also not present in all plants and can therefore be used as another vector to add to hyperspectral nadir data for spectral discrimination of marijuana. Image texture analysis was explored as another approach to using remote sensing data to detect illegal marijuana cultivation. Analysis of close-up, hand- held digital images of marijuana and naturally-occurring plants showed that marijuana plant architecture has distinctive image texture attributes that can be quantified using several pattern recognition approaches. Development continued on a marijuana growth model being developed to help law enforcement officers track marijuana phenology and better time interdiction. Further measurements and modeling of marijuana plant architecture using L-systems were done. A short video illustrating plant growth output by the model was produced. These activities will lead to technologies that will assist law enforcement agencies in all 50 states with the detection and eradication of illegal marijuana cultivation.
