Which feature defines the operation of a multispectral sensor?

A multispectral sensor is designed to capture data across multiple wavelengths of the electromagnetic spectrum, often including visible, infrared, and sometimes ultraviolet light. The key characteristic of such sensors is their ability to simultaneously capture various wavelength bands. This allows for a comprehensive analysis of the surface features being observed, as each band can provide different information about the material properties, health of vegetation, or other environmental characteristics.

The ability to collect data across multiple bands at the same time is crucial for applications in remote sensing, such as land use mapping, agricultural monitoring, and environmental assessments. By gathering data across different wavelengths concurrently, multispectral sensors can produce richer datasets that enable better interpretation and more accurate analyses compared to sensors that only capture data in a single band or limited range of wavelengths.
