- Aerophotographic — Relating to aerophotography, concerning aerial photography; executed through airborne photography from airplanes, helicopters, or drones. It refers to optical equipment, techniques, flight crafts, or mapping materials used in the process of capturing high-altitude images for military, geodetic, or journalistic purposes.
- Aerophotography — The technique of photographing the Earth's surface from high above, using special photographic cameras mounted on board airplanes, helicopters, satellites, or drones; the photographic image obtained through this process. It is widely used in topography, archaeology, meteorology, military espionage, and urban planning.
- Aerial photogram — An aerial photograph of a terrain portion, captured with a special photogrammetric (metric) camera mounted on an airborne platform (airplane, drone, helicopter), having rigorously known geometric and optical characteristics. This metric document serves as a fundamental basis for precise measurements, cartographic restorations, and determining the geographical coordinates of ground elements.
- Aerial photogrammetry — A branch of photogrammetry dealing with determining the shape, dimensions, and position of objects on the Earth's surface, as well as with compiling topographical maps and plans based on measurements executed on aerial photograms. This technical discipline combines elements of optics, aviation, and computational mathematics.

- Airborne gamma-ray spectrometry — An airborne geophysical prospecting method or gamma radiation measurement spectrum conducted using a spectrometer mounted on board an aircraft (airplane, helicopter, or drone). This modern technique allows the remote detection of radioactive anomalies in the shallow layers of the Earth's crust, being utilized in geological mapping and exploration for uranium or thorium deposits.
- Aerogeology — A branch of applied geology that utilizes aerial photographs, satellite data, and multispectral images captured from above (from airplanes or drones) to study the geological structure of the Earth's crust, landforms, tectonic faults, and to locate mineral deposits or underground resources without initial ground intervention.
- Aeromagnetometry — An airborne geophysical method of prospecting and mapping consisting of the continuous measurement and recording of the Earth's magnetic field intensity (or its local variations) using a sensitive magnetometer mounted on board an aircraft (airplane, helicopter, or drone). This modern technique allows the detection of magnetic anomalies caused by subterranean geological structures or ferrous mineral deposits.
- Altitelemetry — A method or technique for remotely measuring the altitude of a moving object (aircraft, rocket, satellite) and automatically transmitting the recorded data, via radio waves or laser, to a ground monitoring station.
- Altitelemeter — A complex device or electronic instrument used to remotely measure the altitude of an object (aircraft, drone, rocket) and automatically transmit the obtained values via radio data streams to a control center.
