An aerial survey refers to a systematic collection of geographic data or information about the Earth's surface, conducted from an elevated position usually using aircraft or drones. It involves capturing images, measurements, and other relevant data over large areas, typically for mapping, monitoring, research, or planning purposes.
Using specialized aerial platforms equipped with cameras, sensors, or LiDAR (Light Detection and Ranging) systems, an aerial survey enables the acquisition of detailed and accurate information about land, water bodies, infrastructure, vegetation, and other features. It provides a bird's-eye view perspective that enables comprehensive coverage of substantial territories within a relatively short period of time.
Aerial surveys have various applications across fields such as cartography, urban planning, environmental monitoring, agriculture, archaeology, and disaster management. They aid in the creation of detailed topographic maps, identification and monitoring of land use patterns, vegetation assessment, identification of potential hazards, and assessment of infrastructure projects.
The collected aerial survey data is usually processed and analyzed using specialized software to generate precise maps, 3D models, or other derived products. Such outputs can support decision-making processes, provide valuable insights for resource management, assist in assessing changes over time, and offer a basis for further scientific research.
In summary, an aerial survey refers to the systematic acquisition of geographical information from an elevated position, typically involving the use of aircraft or drones, enabling wide coverage and accurate data collection for various purposes.
