Remote sensing is the acquisition of information about an object or phenomenon, without making physical contact with the object. In modern usage, the term generally refers to the use of aerial sensor technologies to detect and classify objects on Earth (both on the surface, and in theatmosphere and oceans) by means of propagated signals (e.g. electromagnetic radiation emitted from aircraft or satellites)

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 instantaneous field of view?
The instantaneous field of view is the solid angle subtended by a single pixel of the imaging system. In remote sensing, one can use small angle approximations so that ifov = dx / f * dy / f. dx and dy are the physical dimensions of the pixel.

What is difference of metric photogrammetry and interpretative photogrammetry?
PHOTOGRAMMETRY METRIC PHOTOGRAMMETRY INTERPRETATION Measuring from ground position, elevation distances, areas and volumes. Existing in a qualitative manner like timber stands, water pollution, soils, geological formations, crops and military interpretation. Determine relative locations of points, scales, angle and sizes or shapes of objects. Recognizing and identifying objects on aerial imagery and judging their significance. Preparation of planimetric and topographic maps from photographs. To analysis photographic images Photographs taken from airborne vehicle(aerial) and terrestrial photos(earth-base) Gathered data from a wide variety of sensing instruments such as remote sensing
Way of collecting information from a distance with satellite or other devices?
remote sensing
Importance of remote sensing in civil engineering?
remote sensing
When was Remote Sensing Center created?
Remote Sensing Center was created in 2006-09.
Active and passive remote sensing?
Remote sensing transmits energy that allows an image to be formed. Passive remote sensing collects energy that is reflected or emitted from a surface.
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 is term for the process of gathering information through images taken at a distance?
Remote sensing
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.
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 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.
