7) Interpolation – Uses a Gaussian weighting to average spectra near a sampled
location. Spectra near to the location are weighted higher than spectra far away.
Outputs a file named [email protected] to the working directory. This file contains
the spectra and auxiliary data for each sampled GPS location.
Once the interpolation begins it will ask if the settings are correct. The settings this
refers to are a, b, and the depth increments. By default a and b will be 3 meters, if a
larger search area is desired then these can be updated. If the settings are fine press
YES, if the settings need to be updated select NO. After selecting NO and updating the
settings then press continue to begin the interpolation. After the interpolation is done the
complete light will be green, then press close window or F12 to return to the main
interface.
