What is spectral analysis?

Spectral analysis is a form of image processing that extracts useful information from remote sensing imagery that would might otherwise be missed from the raw pixel values alone.

You may see it referred to as spectral imaging or spectral image processing.

This form of image processing is usually applied to detect features, identify patterns and derive greater insight into the data.

This guide will focus on the application of spectral analysis to visible and near-infrared imagery from sensors on satellite and drone platforms.
