Remote sensing transmits energy that allows an image to be formed. Passive remote sensing collects energy that is reflected or emitted from a surface.
Passive
Cotransport is an active process.
Exocytosis is an active process.
Yes, the process of transport, whether passive or active, requires energy.
The concentration of the keyword is higher in the active form compared to the passive form.
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.
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.
Active remote sensing transmits energy to allow an image to be formed. Passive remote sensing collects energy reflected or emitted from a surface. Active systems direct a bean of energy at a surface and analyze the energy reflected back. An example of active sensing would be a radar. Passive systems are pretty much what the eyes see, and it's like a photograph. Passive sensing radiates visible light.
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).
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).

Passive remote sensing means that the energy being collected is being provided by the environment in which you are collecting. Examples of this type of remote sensing include things as simple as taking a picture with a handheld visible spectrum camera or taking a thermal image of a person's body temperature. Active remote sensing on the other hand involves transmitting energy, allowing that energy to reflect off of the surrounding environment, and then recollecting that energy using a sensor. Examples of this type of remote sensing include sonar devices used by ships and imaging systems that use the returns from laser energy to form an image.
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.

Remote Sensing Center was created in 2006-09.
Active remote-sensing systems use their own energy source to obtain information by transmitting a signal and analyzing the data that is reflected or backscattered. This can include radar systems that emit microwaves or lidar systems that emit laser light.
