UAV LiDAR survey flight over a corridor

UAV/Manned Aircraft LiDAR Surveys

High-density airborne LiDAR collection for engineering-grade deliverables across corridors, urban environments, and complex terrain.

Overview

Convex Geomatics Ltd. delivers survey-grade airborne LiDAR surveys that plug straight into design and construction. From our base in Calgary, Alberta, we map corridors, urban sites, and rugged terrain across Western Canada with both UAV (drone) platforms and manned aircraft.

Why manned aircraft? Helicopters excel where access is hard and detail matters - low, slow flights follow powerlines, pipelines, steep slopes, and tight rights-of-way with uniform point density. Fixed-wing airplanes are the mileage winners for long corridors and regional coverage, keeping schedules tight and unit costs predictable. We often blend helicopter, airplane, and UAV missions to match your airspace, terrain, accuracy, and budget.

Accuracy you can defend. Each survey follows a disciplined workflow-GNSS/IMU PPK/PPPOS, boresight calibration, strip adjustment, and robust ground control with independent checks-delivering consistent, centimetre-level performance for highways, transmission corridors, mine sites, and municipal projects.

Design-ready deliverables. Receive clean, documented outputs to your standards: classified point clouds, hydro-aware terrain models and contours, breaklines, and optional orthophotos. We also provide true-color point clouds and intensity views. Packages ship in DWG/DXF, SHP/GDB, GeoTIFF, and LAS/LAZ with clear datum/projection notes for Civil 3D, MicroStation, and ArcGIS.

Safety, compliance, and communication. Our certified UAV pilots and planners handle NAV CANADA coordination, permits, and NOTAMs. Crews work under documented risk controls, and you can expect clear schedules, proactive updates, and transparent QA/QC throughout.

Tell us what you need - target accuracy, level of detail, corridor length, airspace or site constraints, and timeline. We’ll design the most efficient LiDAR mapping plan - helicopter, fixed-wing, UAV, or a smart hybrid - and deliver clear, design-ready results.
