Aeronautical & OLS Surveys
Integrated aeronautical surveys and obstacle limitation surface (OLS) studies for airports, high-rise developments, helipads, vertiports, and controlled airspace projects.
Airspace Safety Through Precision Survey and Analysis
Aeronautical surveys combine high-accuracy terrain and structure measurements with detailed airspace analysis to assess compliance within protected aviation zones. We conduct OLS modeling and full aeronautical studies for airport infrastructure, high-rise towers, cranes, helipads, and vertiports to verify height clearance and airspace safety.
Our services integrate precise survey data with aviation regulatory criteria to support safe vertical development within controlled airspace.
Our Methodology
Delivering excellence through a proven three-stage workflow
Survey & Elevation Data Capture
Measurement of terrain, proposed tower heights, airport structures, and surrounding obstacles using GNSS, total station, or LiDAR with verified vertical control.
OLS & Airspace Clearance Analysis
Generation of obstacle limitation surfaces and evaluation of height penetration, runway approach clearance, and vertical envelope compliance.
Aeronautical Study & Reporting
Preparation of height clearance studies, penetration reports, and authority-compliant technical documentation.
Applications
Industry sectors and use cases we serve
