Wavelength in remote sensing refers to the distance between two consecutive peaks or troughs of a wave. Different wavelengths of electromagnetic radiation, such as visible light, infrared, and microwaves, are used in remote sensing to gather information about Earth's surface and atmosphere. By analyzing the wavelengths of reflected or emitted radiation, scientists can infer valuable data about the environment being observed.

What is spectral differentiation in remote sensing?
Spectral differentiation in remote sensing refers to the ability to detect and differentiate objects or features based on their unique spectral signatures or characteristics. It involves analyzing the reflectance or emission of electromagnetic radiation across different wavelengths to identify and classify different materials or land cover types. By examining the distinctive spectral responses of various substances, remote sensing technology can provide valuable information for applications such as land cover mapping, resource monitoring, and environmental assessment.
Are remote sensing satellites restricted by the us gov?
Yes, remote sensing satellites operated by U.S. entities are regulated by the U.S. government through the National Oceanic and Atmospheric Administration (NOAA) and the National Reconnaissance Office (NRO). These regulations control the resolution and dissemination of images to protect national security and privacy concerns.
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.
Importance of remote sensing in civil engineering?

When was Pakistan Remote Sensing Satellite created?
Pakistan Remote Sensing Satellite was created in 2011.
When was Indian Institute of Remote Sensing created?
Indian Institute of Remote Sensing was created in 1966.
What is a observation of earth remote-sensing satellite?
Explain how the remote sensing satellites examined the earth from the space?
What are some non-satellite remote sensing technology?
What are some non-satellite remote sensing technology?
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.
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.
Why would a mapmaker use active remote sensing instead of passive remote sensing?
Active remote sensing uses its own electromagnetic radiation and use microwaves. It maps areas hard to map.
What are the main characteristics of microwave remote sensing and optical remote sensing?
Optical remote sensing is affected by cloud covers , rain etc but microwave remote sensing is not.However the optical sensors always need sun as a source of illumination while active microwave sensors don't need.
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.
