Aerial survey is a method of collecting geomatics or other imagery data using airplanes, helicopters, UAVs, balloons, or other aerial methods. Typical data collected includes aerial photography , Lidar , remote sensing (using various visible and invisible bands of the electromagnetic spectrum , such as infrared , gamma , or ultraviolet ) and ...
OpenDroneMap is an open source photogrammetry toolkit to process aerial imagery (usually from a drone) into maps and 3D models. [3] [4] [5] The software is hosted and distributed freely on GitHub. [6] OpenDroneMap has been integrated within American Red Cross's in-field Portable OpenStreetMap system. [7]
Spectroradiometry is a technique in Earth and planetary remote sensing, which makes use of light behaviour, specifically how light energy is reflected, emitted, and scattered by substances, to explore their properties in the electromagnetic (light) spectrum and identify or differentiate between them.

For each photometric system a set of primary standard stars is provided. A commonly adopted standardized photometric system is the Johnson-Morgan or UBV photometric system (1953). At present, there are more than 200 photometric systems. [citation needed] Photometric systems are usually characterized according to the widths of their passbands:
Low altitude aerial photograph for use in photogrammetry. Location: Three Arch Bay, Laguna Beach, California. Photogrammetry is the science and technology of obtaining reliable information about physical objects and the environment through the process of recording, measuring and interpreting photographic images and patterns of electromagnetic radiant imagery and other phenomena.
A3 LightSpeed processing system produces the following output products: 1. Accurately solved vertical and oblique single images of the area of interest. The solution for each image is the result of the photogrammetric bundle block adjustment with self-calibration. 2. SLFs (Super Large Frames), used for stereo photogrammetric mapping. 3.
This is a list of Superfund sites in Massachusetts designated under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) environmental law. . The CERCLA federal law of 1980 authorized the United States Environmental Protection Agency (EPA) to create a list of polluted locations requiring a long-term response to clean up hazardous material contamination
The algorithm, known as variable-pixel linear reconstruction, or informally as "Drizzle", preserves photometry and resolution, can weight input images according to the statistical significance of each pixel, and removes the effects of geometric distortion on both image shape and photometry. In addition, it is possible to use drizzling to ...
