Digital Terrain Modeling
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)
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.
There are a few field studies that sensing cannot put together. Some of the studies are space and earth.
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 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.

Remote Sensing Center was created in 2006-09.
Pakistan Remote Sensing Satellite was created in 2011.
Indian Institute of Remote Sensing was created in 1966.
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.
