John Cartwright, Louis Wasson, Eric Kolstad

Research Objectives• Compare new high-resolution satellite and aerial

MSI data sources for agricultural mapping.• Compare vegetation indices from aerial and

satellite MSI data with field data.• Compare satellite and aerial MSI data and data

products for monitoring crop physiological growth and condition.

• Compare satellite and aerial MSI data and data products for detecting anomalies in research fields.

• Compare satellite and aerial MSI data and data products for assessing crop variability over the growing season.

Practical Objectives• Test and validate the use of mobile computing

portable digital assistant (PDA) devices equipped with GPS and GIS field scouting software for crop management.

• Test and validate methods for integrating data and results between mobile computing GPS/GIS platforms and decision support systems including expert systems and spatially variable application mapping systems
