Aerial surveying is the process of collecting data and information about a large area of land or terrain from an aerial perspective, typically using aircraft or drones equipped with specialized sensors and cameras. Aerial surveying can be used for various purposes, such as land and property surveying, urban planning, environmental monitoring, and infrastructure planning and development.

During an aerial survey, the aircraft or drone flies over the area to be surveyed and captures high-resolution images, LiDAR (Light Detection and Ranging) data, or other types of data using specialized equipment. The data collected is then processed and analyzed to generate maps, 3D models, or other types of geospatial data.

Aerial surveying is often used for large-scale projects that require accurate and comprehensive data over a wide area. It is also a more efficient and cost-effective alternative to traditional ground-based surveying methods, especially in remote or difficult-to-access locations. Aerial surveying has many applications in various industries, including construction, urban planning, agriculture, and mining.
