12 September 2005 Measurement of spectral signatures of invasive plant species with a low cost spectrometer
Author Affiliations +
A low cost, portable spectrometer was evaluated for use in collecting signature spectra from vegetation at three riparian sites in Colorado 6/8/05 - 6/11/05. An Ocean Optics HR4000CG-UV-NIR spectrometer configured with a fiber optics coupled Teflon diffuser was used to obtain reflectance spectra from a number of invasive and natural riparian plant species at wavelengths spanning 400 to 900 nm. A number of tests were conducted to quantify sources of measurement error. These tests included a determination of dark and stray light bias, wavelength registration, and integration time corrections over constant and varying temperature. Reflectance spectra from artificial and natural targets were collected in concert with NASA-Goddard and NASA-Stennis field teams utilizing an Analytical Spectral Devices (ASD) FieldSpec Pro FR spectrometer (350 to 2500 nm). A brief comparison of reflectance spectra obtained with the HR4000CG-UV-NIR and the FieldSpec Pro FR is presented. Future work is discussed.
