OLS Survey



OLS (Obstacle Limitation Surfaces) Survey is a specialized type of topographical survey conducted around airports and aerodromes to ensure safe air navigation. It involves the identification and mapping of natural and man-made obstacles that may interfere with aircraft during takeoff, landing, and approach. The survey defines critical zones and height restrictions based on ICAO guidelines, helping to maintain unobstructed flight paths and secure airspace. It is essential for planning new constructions, evaluating terrain elevations, and ensuring compliance with aviation safety regulations.

OLS Surveys are crucial for airport authorities, aviation regulators, and urban planners in maintaining flight safety and operational efficiency. These surveys support airspace design, infrastructure development, and obstacle clearance assessment. The collected data is used to monitor existing obstacles, plan mitigation strategies, and guide zoning decisions near airport vicinities. By identifying potential hazards in advance, OLS surveys contribute significantly to minimizing risks and enabling the smooth functioning of both civil and military aviation operations.
