WHY CHOOSE OUR LIDAR WORKFLOW
LiDAR can record ground returns between vegetation where imagery may not provide a clear terrain surface. Classification and validation depend on canopy, terrain, flight design, and ground control.
Fixed-wing VTOL and multirotor options can reduce field time on linear highway, rail, pipeline, and powerline surveys. The right platform depends on area, access, permits, and required outputs.
We plan the required flight permissions and can also scope GPS survey or mobile laser scanning when a non-drone option better fits the schedule or site conditions.
Select aerial LiDAR, photogrammetry, GNSS survey, or mobile SLAM scanning. We can combine methods to match site access, scale, and deliverables.
Prepare point clouds, terrain models, contours, and GIS layers for review in the agreed project workflow, including Terra MapX where applicable.
Our documented work shows how LiDAR scales from detailed terrain mapping to long corridors and wide coastal areas, with structured data ready for engineering and planning decisions.
FIELD CHALLENGES SOLVED
Photogrammetry may not resolve ground clearly beneath vegetation. LiDAR can add ground returns between branches, while classification and QA confirm whether the terrain model is suitable for design use.
Ground control and site access still matter on long corridors. Aerial LiDAR can provide a continuous baseline, with ground survey used where control, boundaries, or verification are required.
Remote capture can reduce exposure to difficult terrain, but flight planning, site controls, and local permissions remain essential. LiDAR data supports assessment; it does not replace geotechnical or safety decisions.
Combine GNSS control, project benchmarks, and check points to document the reference system and validate delivered data. The required datum and control plan are confirmed for each project.
Point density is planned around area, platform, altitude, terrain, classification, and deliverables. We confirm the specification before capture and report achieved density in QA documentation.
Where useful, we coordinate permits, aerial capture, GNSS control, mobile scanning, processing, and CAD/GIS outputs as one agreed scope.
TECHNIQUES & METHODS
Deploying DJI Matrice 400 with Zenmuse L3 and M350 RTK with Zenmuse L2. Features multi-return laser pulses up to 240 kHz, integrated RGB cameras, and real-time RTK positioning. Engineered for highways, powerline rights-of-way, and plant expansions requiring ±5 cm horizontal and vertical precision with point densities exceeding 100 to 240+ pts/m².
For wider-area VTOL Fixed Wing missions, we can scope the appropriate platform. Payload, control method, coverage, target density, and outputs are confirmed from the project requirements and operating approvals.
We offer FJD Trion S2 mobile SLAM scanning in handheld or backpack configurations for indoor facilities, plants, substations, corridors, and tunnels. It captures 3D geometry while the operator moves through the site; control and validation requirements are agreed per project.
Ground control can use dual-frequency GNSS, project benchmarks, and independent check points. We document the project reference system and QA results; cadastral or land-registry submissions require a separate scope and applicable authority requirements.
Process raw laser trajectories, IMU observations, and GNSS RINEX data in Terra Mapper or the agreed processing workflow. PPK/RTK and control checks are applied when required by the mission and accuracy specification.
Terra GeoAIX can assist feature extraction in supported road-corridor, solar-farm, and construction-earthworks workflows. Outputs are reviewed and delivered according to the agreed classification specification.
Use ArcGIS Pro, Civil 3D, and other agreed tools to check breaklines, contours, coordinate reference, and deliverable structure before handover.
Publish approved layers and point clouds through Terra MapX or another agreed delivery channel. MapX supports 2D, 3D, and point-cloud views; access, storage, and security requirements are agreed per project.
ENGINEERING DELIVERABLES
PRACTICAL LIDAR APPLICATIONS
Create georeferenced point clouds, elevation profiles, and terrain models for road, powerline, and pipeline route studies. Right-of-way and design support can be derived from agreed survey outputs; asset inspection is a separate scope.
Classify LiDAR returns to separate ground, vegetation, and structural features when required. Bare-earth models and vegetation context support site planning and environmental baselines, subject to canopy, terrain, density, and QA requirements.
Compare point clouds and terrain models for stockpile volumes, cut-and-fill checks, haul-road context, and repeat-survey change analysis. Survey outputs support planning; slope-stability decisions remain with the qualified geotechnical team.
Use terrain, point-cloud, and imagery outputs for solar site screening, terrain context, and environmental baseline mapping. Irradiance modelling, flood-risk analysis, or panel inventory are additional analytical scopes to confirm before the project.
