What type of transport is carbon dioxide passive or active?
Passive (diffusion).
I was driven here by my mum active or passive?
Passive
What are passive and active transport?
Passive transport and active transport are transport of materials across membranes. Passive requires no energy, while active does.
Is Mark was given a warning active or passive?
Passive
Is transport through aquaporin passive or active?
passive
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.
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 is the difference between active and passive remote sensing systems in geography?
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.
What is used to gather data in a passive remote sensing system?
gps
What is passive remote sensing?
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.
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.
Way of collecting information from a distance with satellite or other devices?
remote sensing
What is used to gather data in an active remote-sensing system?
Hi, I'm Josephine, and I'm barely learning this, since I'm in 6 grade. A radar is used to gather data in an active remote sensing system. Funny, I have this question in my study guide. :)
Importance of remote sensing in civil engineering?
remote sensing
A satellite imaging system that beams electromagnetic at the surface and then records the energy reflected is what?
It would be Active Remote Sensing.
When was Remote Sensing Center created?
Remote Sensing Center was created in 2006-09.
When was Indian Institute of Remote Sensing created?
Indian Institute of Remote Sensing was created in 1966.
