Remote sensing can detect vegetation in the red wavelengths because chlorophyll, the pigment responsible for photosynthesis in plants, absorbs light most efficiently in the red part of the spectrum. This absorption leads to a decrease in reflectance in the red band, making vegetation appear red in remote sensing imagery.

Why would amapmarker use active remote sensing instead of passive remote sensing?
A mapmaker might use active remote sensing over passive remote sensing because active remote sensing provides its own source of energy to illuminate the target, allowing for more control over the data collected. This can result in better resolution and accuracy in mapping features of interest.
What is the opposite from remote sensing?
The opposite of remote sensing is close-up sensing, where data is collected from objects or phenomena in close proximity to the sensor or observer. This type of sensing involves direct contact or nearness to the subject being observed, as opposed to remote sensing which involves collecting data from a distance.
What are the four types of remote sensing?
The four types of remote sensing are passive remote sensing (detects natural radiation), active remote sensing (emits energy and measures its reflection), aerial photography (uses cameras on aircraft or satellites), and satellite imaging (capturing images from space using satellites).
What are three types of remote sensing?
Three types of remote sensing are passive remote sensing (detects natural radiation emitted or reflected by objects), active remote sensing (sends out its own radiation to illuminate objects), and aerial photography (capturing images of the Earth's surface from aircraft or satellites).
How is active remote sensing different from passive remote sensing?
Passive remote sensing picks up wave lengths of the light spectrum occurring on their own such light in photography. Active remote sensing will send out a wavelength of the spectrum and measure how it bounces back like radar.

What is band ratio in remote sensing?
Band ratio in remote sensing is a technique that involves dividing the pixel values of one band of an image by the pixel values of another band. This can enhance certain features or properties in the image, such as vegetation health or mineral composition, by highlighting the differences in spectral responses between the two bands. It is a common method used for image interpretation and analysis in various remote sensing applications.

What are Remote Sensing observational platforms?
The platforms that harbor remote sensing sensors (eg. cameras) are called remote sensing platforms. In earlier days, during military reconnaissance, pigeons attached with cameras were made to fly over areas of interest. In this case the platform is the bird. Balloons, airplanes and satellites that carry remote sensing sensors are examples of remote sensing platforms.
