Birdseye surveys are a process of acquiring information about a specific area from an aerial perspective. This technique is also known as aerial surveys, aerial mapping, or aerial photography. The synonyms for birdseye surveys include drone surveys, remote sensing, topographic surveys, and aerial imagery. Drone surveys involve using unmanned aerial vehicles to capture images and data from a birdseye view, while remote sensing involves using satellites and other remote sensors to gather information about a particular area. Topographic surveys, on the other hand, focuses on the three-dimensional features of the land. Lastly, aerial imagery involves capturing photos or videos from a high elevation to gather information about a specific area. All these techniques are used in various industries, including construction, mining, and agriculture.
