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)
How did remote sensing change the way geographic data were obtained?
Remote sensing allowed for the collection of geographic data without physically being on the ground. This technology enables the capture of information about the Earth's surface from a distance, using satellites, drones, or aircraft. Remote sensing has made it possible to gather data over large areas quickly and efficiently, revolutionizing the way geographic data are obtained.
How do geographers find their information?
Geographers find information through a variety of methods, including fieldwork, remote sensing, geographic information systems (GIS), satellite imagery, surveys, maps, and secondary data sources such as census data and academic research. They may also use qualitative and quantitative research techniques to gather and analyze data for their studies.
What is band ratio in remote sensing?
Band ratio in remote sensing is a technique that involves dividing the pixel values of one band of an image by the pixel values of another band. This can enhance certain features or properties in the image, such as vegetation health or mineral composition, by highlighting the differences in spectral responses between the two bands. It is a common method used for image interpretation and analysis in various remote sensing applications.
Intsrument that gather and record information from a distance?
A remote sensing instrument is used to collect and record information from a distance. These instruments are often mounted on satellites or aircraft and can capture data about the Earth's surface without direct physical contact. Examples include cameras, radars, and spectrometers.
What is used to gather data in a passive remote sensing system?
gps

Importance of remote sensing in civil engineering?
remote sensing
Way of collecting information from a distance with satellite or other devices?

When was Remote Sensing Center created?
Remote Sensing Center was created in 2006-09.
What is wavelength in remote sensing?
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 used to gather data in an active remote-sensing system?
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.
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?
