Reconnaissance is the process of gathering information about a specific area or target, often used in military operations. It helps commanders understand the terrain, enemy positions, and potential threats before making strategic decisions. This information can be collected through various means, including aerial surveys, satellite imagery, and on-the-ground observations. In addition to military applications, reconnaissance is also used in fields like geography, environmental science, and urban planning. For example, researchers may conduct reconnaissance to assess natural resources or study the impact of human activities on ecosystems. This preliminary investigation is crucial for informed planning and decision-making.
