What color represents vegetation in remote sensing images?

In remote sensing images, vegetation is primarily represented by the color green. This is due to the chlorophyll in plants, which reflects green wavelengths of light strongly while absorbing red and blue wavelengths. This characteristic is crucial for identifying and analyzing vegetation health and cover through satellite imagery or aerial surveys.

When analyzing remote sensing data, green hues typically indicate healthy vegetation, while variations in tone may indicate different types of plants or varying health conditions. The infrared spectrum, particularly near-infrared, is often employed in vegetation analysis as well, since healthy plants reflect more infrared light than stressed or absent vegetation.

Understanding why vegetation is represented by green in remote sensing can lead to better analysis in fields like agriculture, forestry, and ecology, allowing for enhanced monitoring and management of natural resources.
