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.
The term for the process of gathering information through images taken at a distance is "remote sensing." This technique involves the use of satellite or aerial imagery to collect data about the Earth's surface without direct contact. Remote sensing is widely used in various fields, including environmental monitoring, agriculture, and urban planning, to analyze and interpret spatial information.
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.
Indian Institute of Remote Sensing was created in 1966.
Pakistan Remote Sensing Satellite was created in 2011.

Explain how the remote sensing satellites examined the earth from the space?
What are some non-satellite remote sensing technology?
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.
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.
Active remote sensing uses its own electromagnetic radiation and use microwaves. It maps areas hard to map.
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.
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.
remote sensing satellites develop highly detailed and accurate maps on earths surface.
