ABSTRACT
This chapter explores a low altitude, low endurance Unmanned Aerial Vehicles (UAV). A UAV—also known as a drone, unmanned aircraft system (UAS), and by several other names—is an aircraft without a human pilot aboard. Typically, UAVs are presented by fixed wing, rotary, kites, balloons, gliders, and other aerial platforms. UAVs can be classified by a broad number of characteristics, including weight, engine, and payload. The most important toolset that enables mapping, surveillance and remote sensing is a sensor suite. Photogrammetrically there are two possible types of UAV aerial imaging: vertical images and oblique images. The ground sample distance (GSD), is one of the most important parts of any imagery specification. It is given for every single pixel of the image, that is, how much ground is covered. A higher GSD means better resolution and also means clearer identification of objects on the ground. One of the great benefits that photogrammetry and computer vision are deploying is the stereoscopic/multiview processing capability.
