Introduction

A reflectance panel has known spectral properties and can be used to convert imagery to reflectance values. The process of converting imagery into reflectance values allows for time series comparisons of imagery because it normalizes the data for different lighting conditions.

The reflectance panel is an optional component for the 6X sensor. The reflectance panel is a white balance card used to calibrate 6X images by measuring the reflectance of the card across the spectrum of light captured by the sensor (for example, red, green, blue, near infrared, and/or red edge bands).
