What does a multiband raster consist of?

1. A raster with one band of information.

2. A raster with 2 or more bands of information from different sensors.

3. A raster showing only color information.

4. A single band representing composite data.

The correct answer is: A raster with 2 or more bands of information from different sensors.

A multiband raster consists of multiple bands of information, typically gathered from different sensors or capturing various wavelengths of light. Each band represents a different characteristic or aspect of the data, such as different parts of the electromagnetic spectrum. For instance, in satellite imagery, visible light, infrared, and thermal bands may be used to capture a comprehensive view of the Earth's surface. This capability allows for advanced analysis and interpretation of the data, such as distinguishing between different types of land cover, assessing vegetation health, or monitoring environmental changes. The presence of multiple bands enhances the potential for detailed analysis, enabling users to take advantage of multispectral data, which is essential in fields like remote sensing, agriculture, and environmental science. In contrast, the other options focus on either single-band functionality or aspects that do not represent the core concept of a multiband raster, thus highlighting why the correct answer involves multiple bands of information.
