Abstract

The paper describes an all-terrain motorized platform for deploying sensors and compares data collected by means of that system with those collected by means of hand-held sensors. The results not only highlight the greater variability in spectra that can be expected when deploying field radiometers by hand but, more importantly, they quantify the difference. Researchers should be aware of the potential for diminishing the validity of findings based on reflectance spectra acquired by means of hand-held sensors.
