Figure 5a. Acquisition of visible/near infrared (VNIR) spectrum a large sandy-bottom (see inset) wash bisecting the Cave Creek scar. Data were collected using the ASD 1143 field spectrometer, which gathers spectra at 4 wavenumber resolution from 350 - 950 nanometers (see Figure 5b below). Field spectra will be used to analyze surface material as well as perform vicarious calibration of the ASTER data.

Figure 5b. (below) Typical VNIR field spectra of the fire scar ground cover and soil types. Almost all the spectra show evidence of a percentage of photosynthesizing material (large reflectance increase at ~ 700 nm). Also shown are the three ASTER band passes (VNIR 1-3).
