Ground truth, the Glossary

Ground truth is information that is known to be real or true, provided by direct observation and measurement (i.e. empirical evidence) as opposed to information provided by inference.^[1]

Aerial photography

Aerial photography (or airborne imagery) is the taking of photographs from an aircraft or other airborne platforms.

See Ground truth and Aerial photography

Atmospheric correction

Atmospheric correction is the process of removing the scattering and absorption effects of the atmosphere on the reflectance values of images taken by satellite or airborne sensors.

See Ground truth and Atmospheric correction

A baseline in science (including medicine) is the initial conditions found by observation and measurement at the beginning of a survey or clinical trial or which is used for comparison with later data collected during or after the survey or trial to identify and measure changes, often with the intention of assessing the effects of a treatment or procedure.

See Ground truth and Baseline (science)

Calibration

In measurement technology and metrology, calibration is the comparison of measurement values delivered by a device under test with those of a calibration standard of known accuracy.

See Ground truth and Calibration

Cartography

Cartography (from χάρτης chartēs, 'papyrus, sheet of paper, map'; and γράφειν graphein, 'write') is the study and practice of making and using maps.

See Ground truth and Cartography

Computer stereo vision

Computer stereo vision is the extraction of 3D information from digital images, such as those obtained by a CCD camera. Ground truth and Computer stereo vision are Applications of computer vision.

See Ground truth and Computer stereo vision

Empirical evidence

Empirical evidence for a proposition is evidence, i.e. what supports or counters this proposition, that is constituted by or accessible to sense experience or experimental procedure.

See Ground truth and Empirical evidence

Foundationalism

Foundationalism concerns philosophical theories of knowledge resting upon non-inferential justified belief, or some secure foundation of certainty such as a conclusion inferred from a basis of sound premises.

See Ground truth and Foundationalism

Geographic information system

A geographic information system (GIS) consists of integrated computer hardware and software that store, manage, analyze, edit, output, and visualize geographic data.

See Ground truth and Geographic information system

Gold standard (test)

In medicine and medical statistics, the gold standard, criterion standard, or reference standard is the diagnostic test or benchmark that is the best available under reasonable conditions.

See Ground truth and Gold standard (test)

Hypothesis

A hypothesis (hypotheses) is a proposed explanation for a phenomenon.

See Ground truth and Hypothesis

Inference

Inferences are steps in reasoning, moving from premises to logical consequences; etymologically, the word infer means to "carry forward".

See Ground truth and Inference

Iraq War

The Iraq War, sometimes called the Second Persian Gulf War, or Second Gulf War was a protracted armed conflict in Iraq from 2003 to 2011. It began with the invasion of Iraq by the United States-led coalition that overthrew the Ba'athist government of Saddam Hussein. The conflict continued for much of the next decade as an insurgency emerged to oppose the coalition forces and the post-invasion Iraqi government.

Meteorology

Meteorology is a branch of the atmospheric sciences (which include atmospheric chemistry and physics) with a major focus on weather forecasting.

See Ground truth and Meteorology

Military slang

Military slang is an array of colloquial terminology used commonly by military personnel, including slang which is unique to or originates with the armed forces.

See Ground truth and Military slang

Mount Rushmore

The Mount Rushmore National Memorial is a national memorial centered on a colossal sculpture carved into the granite face of Mount Rushmore (Lakota: Tȟuŋkášila Šákpe, or Six Grandfathers) in the Black Hills near Keystone, South Dakota, United States.

Naive Bayes spam filtering

Naive Bayes classifiers are a popular statistical technique of e-mail filtering.

Pixel

In digital imaging, a pixel (abbreviated px), pel, or picture element is the smallest addressable element in a raster image, or the smallest addressable element in a dot matrix display device.

See Ground truth and Pixel

Remote sensing

Remote sensing is the acquisition of information about an object or phenomenon without making physical contact with the object, in contrast to in situ or on-site observation. Ground truth and Remote sensing are Applications of computer vision.

See Ground truth and Remote sensing

Research

Research is "creative and systematic work undertaken to increase the stock of knowledge".

See Ground truth and Research

Satellite

A satellite or artificial satellite is an object, typically a spacecraft, placed into orbit around a celestial body.

See Ground truth and Satellite

Satellite imagery

Satellite images (also Earth observation imagery, spaceborne photography, or simply satellite photo) are images of Earth collected by imaging satellites operated by governments and businesses around the world.

See Ground truth and Satellite imagery

Stars and Stripes (newspaper)

Stars and Stripes is a daily American military newspaper reporting on matters concerning the members of the United States Armed Forces and their communities, with an emphasis on those serving outside the United States.

Statistical model

A statistical model is a mathematical model that embodies a set of statistical assumptions concerning the generation of sample data (and similar data from a larger population).

See Ground truth and Statistical model

Subjectivity and objectivity (philosophy)

The distinction between subjectivity and objectivity is a basic idea of philosophy, particularly epistemology and metaphysics.
