Télédétection

methods of information-gathering about the Earth's surface from a distance.

Non-intrusive survey methods used to find archaeological sites; these may include aerial reconnaissance and geophysical techniques such as magnetometry, radar, resistivity, and conductivity.

The use of various technologies to make observations and measurements at a target that is usually at a distance or on a scale beyond those observable to the naked eye.

way of getting information about an object without having the measuring device in direct contact with it. Examples include radar’s use of radio waves and sonar’s use of sound waves to detect objects.

Remote sensing refers to the use of satellite or other above-ground apparatus to detect or track information about a system or area. Examples of remote sensing within the water industry may be include the tracking of moisture levels in drought-stricken areas, or the monitoring of algae levels in various bodies of water.

A method of regulating the excitation voltage to the load cells. Some indicators compensate for voltage drops occurring between the indicator and load cells by increasing the indicator excitation outp [..]

[GIS dictionary definition] Remote sensing is the science of obtaining information about the Earth without physically being there. Examples remote sensing techniques are by satellite, unmanned aerial [..]

is the use of various technologies to make observations and measurements at a target that is usually at a distance or on a scale beyond those observable to the naked eye.

Remote sensing is a way of collecting and analysing data to get information about an object without the instrument used to collect the data being in direct contact with the object. Remote sensing can [..]

Acquisition of raster images of the Earth, often involving spectral frequencies other than the visible band, by devices typically carried on airborne or satellite platforms. Sometimes refers also to i [..]

Process of detecting and (or) monitoring chemical or physical properties of an area by measuring its reflected and emitted radiation.

The study of Earth surface conditions and materials from airplanes and satellites by means of photography, spectroscopy, or radar.

Viewing something from a distance. Satellites and other instruments are used to collect a variety of remote sensing data: visible light:

the acquisition of information about an object by a recording device that is not in physical contact with it. Today, the term is commonly used to describe the process of collecting, viewing, interpret [..]

The process of and the technologies for recording and measuring terrestrial features and activities at a distance from the surface (such as from aircraft or satellites).

A means by which the power supply uses external "sensing" leads to monitor a stabilized output voltage and/or current at some point external to the power supply [..]

A technique of regulating the output voltage of a power supply at the load by means of sensing leads which go from the load back to the regulator. This compensates for voltage drops in the load leads.

A method that broadly refers to capturing imagery from a distance, usually from satellites, but can also refer to aerial photography. (Recording, Documentation and Information Management for Historic Places - Guiding Principles; Getty Conservation Institute, 2008).

Remote sensing - the science, technology, and art of obtaining information about objects from a distance. Remotely sensed data takes many forms, including aerial photography, digital satellite imagery, and radar. From: Remote Sensing for GIS Managers - Stan Aronoff

The capture of information about the Earth from a distant vantage point. The term is often associated with satellite imagery but also applies to aerial photography, airborne digital sensors, ground-ba [..]

Any technique for analyzing landscape patterns and trends using low altitude aerial photography or satellite imagery; any environmental measurement that is done at a distance.

The collection and interpretation of information about an object without physical contact with the object; e.g., satellite imaging, aerial photography, and open path measurements.

The collection and interpretation of information about an object without physical contact with the object; e.g., satellite imaging, aerial photography, and open path measurements.

A set of non-invasive techniques used to locate archaeological sites either under ground or under water, without disturbing the archaeological deposits themselves.

The technology of acquiring data and information about an object or phenomena by a device that is not in physical contact with it. In other words, remote sensing refers to gathering information about [..]

Remote sensing is the process of acquiring information about an object or phenomenon without making actual physical contact with it, as opposed to onsite observation or onsite sensing. This often requ [..]

The acquisition of information on some property of a target object or material without being in physical contact with it. In the broadest terms, this is done by using instruments or scanners to sense [..]

Instruments that record characteristics of objects at a distance, sometimes forming an image by gathering, focusing, and recording reflected light from the Sun, or reflected radio waves emitted by the spacecraft.

the identification of data, usually about features of the earth or other bodies in space, from a satellite, aeroplane etc[20]

the acquisition of information about an object without physical contact. Usually associated with the acquisition of information about the Earth's surface by electronic and/or optical instruments [..]

(science) The capability to gain information about an object without coming in direct contact with it, for example via satellite imaging or thermal imaging. (parapsychology) Remote viewing.

Remote sensing means the non-contiguous field reconnaissance, as a rule, by aeroplanes or satellite systems. There is a whole range of remote sensing methods. Passive remote sensing constitutes the ca [..]
