Advanced Aerial Imaging Technologies
Expert-defined terms from the Advanced Certificate in Aerial Surveillance Systems course at London School of Planning and Management. Free to read, free to share, paired with a globally recognised certification pathway.
Advanced Aerial Imaging Technologies #
The use of advanced aircraft, sensors, and software to capture high-resolution images and data from the air. This technology is used in various industries, including military, agriculture, construction, and mining.
Airborne Platforms #
The aircraft or unmanned aerial vehicles (UAVs) used to carry imaging sensors and equipment. Examples include helicopters, fixed-wing airplanes, and multirotor drones.
Active Sensors #
Sensors that emit energy, such as radar, and measure the reflection off of objects to determine distance, size, and shape.
Camera Systems #
The different types of cameras used in aerial imaging, including multispectral, hyperspectral, and thermal cameras. These cameras capture different wavelengths of light to provide detailed information about the earth's surface.
Data Processing #
The process of converting raw image data into usable information. This includes image enhancement, mosaicking, and orthorectification.
Elevation Models #
Digital representations of the earth's surface, created using aerial imaging data. These models can be used for 3D visualization, terrain analysis, and volumetric calculations.
Georeferencing #
The process of aligning aerial images with real-world coordinates, allowing for accurate measurement and analysis.
GIS (Geographic Information Systems) #
Software used to manage, analyze, and visualize geographic information. GIS is used in conjunction with aerial imaging to create maps, perform spatial analysis, and make informed decisions.
Hyperspectral Imaging #
A type of imaging that captures detailed information about the chemical and mineral composition of objects by measuring reflected light across a wide range of wavelengths.
LiDAR (Light Detection and Ranging) #
An active remote sensing technology that uses laser light to measure distances to the earth's surface, creating highly accurate 3D models.
Multispectral Imaging #
A type of imaging that captures information about objects in several specific wavelength bands, such as red, green, and blue.
Object Detection #
The process of identifying and locating specific objects within an image, such as buildings, cars, or trees.
Orthophotos #
Georeferenced aerial images that have been corrected for lens distortion and topographic relief, providing a true-to-life representation of the earth's surface.
Photogrammetry #
The science of making measurements from photographs, including the creation of 3D models and maps.
Pix4D #
A popular software package used for processing and analyzing aerial imaging data.
Radar #
An active sensor that uses radio waves to detect the range, altitude, and velocity of objects.
Remote Sensing #
The acquisition of information about the earth's surface and atmosphere through the use of sensors on aircraft or satellites.
SAR (Synthetic Aperture Radar) #
A type of radar that uses the motion of the aircraft or satellite to simulate a larger antenna, providing high-resolution images of the earth's surface.
Structure from Motion (SfM) #
A photogrammetry technique used to create 3D models from a series of overlapping images.
Thermal Imaging #
A type of imaging that captures heat signatures, allowing for the detection of objects or areas with different temperatures.
UAV (Unmanned Aerial Vehicle) #
An aircraft piloted remotely or autonomously, used for aerial imaging and other tasks.
Volumetric Calculations #
The process of measuring the volume of a stockpile, excavation, or other feature using aerial imaging data.
