What is the term for the line that provides starting points for each crew member during a search operation?

The term "base line" in the context of a search operation refers to the established line that serves as a reference point or starting point for crew members. This line helps ensure that all team members are aligned in their search efforts and can systematically cover an area without overlapping or missing critical zones. By providing this structured approach, the base line enhances efficiency and coordination among the rescue teams, leading to a more effective operation overall.

Each crew member can use the base line to orient themselves and determine their search patterns, which is essential in optimizing the effectiveness of the search, especially in large or complex areas. Overall, the concept of a base line underscores the importance of organization and communication in search operations.
