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 ...
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.

The sensitivity usually depends on the optical system, detectors and filters used. 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]
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.
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.

According to the United States Census Bureau, the town has a total area of 24.6 square miles (64 km 2), of which 24.4 square miles (63 km 2) is land and 0.3 square miles (0.78 km 2), or 1.06%, is water. The highest point in Sudbury is on the north slope of Nobscot Hill, and the highest summit is Tippling Rock. [27] In 1650, the town included ...
