Overview
Convex Geomatics Ltd. provides 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 Alberta, BC, and Saskatchewan using UAV (drone) and manned aircraft.
Choose the right platform. Helicopters excel where access is hard and detail matters — low, controlled flights follow powerlines, pipelines, steep slopes, and tight rights-of-way with uniform point density. Fixed-wing airplanes are ideal for long corridors and regional coverage, keeping schedules tight and unit costs predictable. We can also deploy UAV LiDAR for smaller sites and high-detail areas, or combine platforms for the best outcome. For surveys at street-level on roads or interiors, see our mobile LiDAR mapping service. For deeper context on choosing between LiDAR and photogrammetry, see our LiDAR vs Photogrammetry in Alberta comparison.
Defensible accuracy. Each project follows a disciplined workflow — GNSS/IMU PPK/PPP, boresight calibration, strip adjustment, and ground control with independent checks — delivering consistent centimetre-level performance for highways, transmission corridors, mine sites, and municipal projects. What separates a good LiDAR provider from a bad one? See our breakdown: Not All LiDAR Services Are Equal.
Design-ready deliverables. Receive clean, documented outputs to your standards: classified point clouds, hydro-aware terrain models and contours, breaklines, and optional orthophotos. Deliverables are available in DWG/DXF, SHP/GDB, GeoTIFF, and LAS/LAZ with clear datum/projection notes for Civil 3D, MicroStation, and ArcGIS.
Safety and compliance. Our certified UAV pilots and planners handle NAV CANADA coordination, permits, and NOTAMs where required. Expect clear schedules, proactive updates, and transparent QA/QC from mobilization to final delivery.
Tell us what you need — target accuracy, level of detail, corridor length, airspace/site constraints, and timeline. We'll design the most efficient LiDAR mapping plan for Calgary and Alberta and deliver clear, design-ready results.
LiDAR vs Other Survey Methods
Choosing the right capture method for an Alberta project depends on terrain, accuracy needs, and timeline. Here is how airborne LiDAR compares to the alternatives we offer.
| Capability | Airborne LiDAR | Photogrammetry | Mobile LiDAR | Total Station / GNSS |
|---|---|---|---|---|
| Bare-earth under vegetation | Excellent | Limited | N/A | Manual only |
| Coverage rate (km/day) | Very high | High | High (corridors) | Low |
| Vertical accuracy | ±1–6 cm | ±3–10 cm | ±2–3 cm | ±5–15 mm |
| Texture / orthophoto | Optional | Native | Optional | No |
| Cloudy / low-light conditions | Works | Limited | Works | Works |
| Best fit for | Corridors, dense canopy, terrain | Open sites, visual context | Roads, urban, interiors | Spot accuracy, layout |
