Drones or UAVs are designed to replace some terrestrial surveying equipment. As with manual data collection methods, organizations in a variety of industries can use drones for project progress monitoring; to prepare for or to conduct site inspections; to assess sites and identify problems; to procure footage or information for marketing and reporting purposes; to conduct research; and for other forms of analysis and processing. Indeed, drone data collection means far more than just launching a drone equipped with a camera and hovering it above the site to snap a few photos. They utilize distinct technologies to produce incredibly information- rich datasets.
