How do you look for water on other planets or moons?
We can look for it by using these tecniqes. •Seeing it in rocks (meteorites) •Seeing it gravitationally •Seeing it spectroscopically (remote sensing) •Seeing morphological features of it (remote sensing) •Seeing it (remote sensing)
Why is ku band microwave used in remote sensing of sea ice?
The Ku-band (12-22 GHz frequency, 2 cm wavelength) is much stronger than the the other bands (x, c, l). With its high capability it is used to study the properties of sea ice and thinner snow, where there is weaker response by the other bands. Using Ku-band , we get a stronger backscattered radiation from the surface and hence the surface type properties could be studied more in detail.
What kind of data do field studies gather that remote sensing cannot gather?
There are a few field studies that sensing cannot put together. Some of the studies are space and earth.
What are the uses of remote sensing?
The advantages of remote sensing include the ability to collect information over large spatial areas; to characterize natural features or physical objects on the ground; to observe surface areas and objects on a systematic basis and monitor their changes over time;
In addition to using data from remote sensing cartographers gets data to make maps from?
In addition to remote sensing data, cartographers also use ground surveys, GPS technology, aerial photography, and geographic information systems (GIS) to collect data for making maps. These methods help ensure accuracy and provide additional layers of information that can be used for mapping purposes.
What are band ratio in remote sensing?
Band ratio is a technique used in remote sensing that involves dividing the value of one spectral band by another to enhance certain features in the data. By creating ratios of bands, specific information about objects or materials in the scene can be highlighted, such as vegetation health, soil moisture content, or mineral composition. These ratios can help in identifying and mapping different land covers and understanding the underlying properties of a target area.
Importance of remote sensing in civil engineering?

Why is remote sensing red on vegetation?
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.
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.
When was Pakistan Remote Sensing Satellite created?
Pakistan Remote Sensing Satellite was created in 2011.
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.
