# Spectral library collection method

Spectral libraries are collections of spectral reflectance signatures representing groundcover features that frequently occur in a study area. These data are collected to:

- Determine if features can be differentiated from each other based on reflectance signatures
- as input for mapping algorithms that match pixel values to target spectral reflectance signatures;

Spectrometers are used to collected the spectral signatures of the groundcover features that make up the spectral library. There are several methods for acquiring spectral signatures e.g. measure directly in the field or take a sample and measure it in laboratory environment.
