02 FROM RAW DATA TO RESULTS

Four stages between the flight and the decision.

A single survey produces a dataset that can support several engineering products.

  1. 01 / CAPTURE

    The LiDAR sensor scans the site from the air

    The drone follows a flight plan calculated for the area and its relief. The sensor emits laser pulses and records each return, including through vegetation gaps.

  2. 02 / PROCESS

    Data is georeferenced and classified

    The GNSS/IMU trajectory is adjusted, the cloud is georeferenced to the project coordinate system, and points are classified into ground, vegetation, buildings and structures.

  3. 03 / MODEL

    The cloud becomes usable models

    From the classified points we derive terrain and surface models, contours, cross sections and 3D meshes according to project scope.

  4. 04 / DELIVER

    You receive information you can act on

    We deliver open, documented files ready for CAD, BIM and GIS workflows, together with the technical report for the survey.

03 SERVICES

Data built for engineering, planning and analysis.

Select a service to see its scope, deliverables and typical applications.

What is included

  • Ground point filtering and classification

Fewer returns reach the ground under dense vegetation. There the model is interpolated from fewer points, and the report says so.

Request: Digital Terrain Models

Aerial measurement of stockpiles, material banks and excavation fronts. Volumes are computed against a base surface agreed with you and documented for audit. Because the whole surface is measured rather than sampled by sections, the result does not depend on their spacing.

04 INDUSTRIES

One dataset, different decisions.

Every sector uses the point cloud differently. Choose yours.

Construction

From natural ground to built state, measured at every stage.

Initial survey for detailed design, earthworks control and progress documentation with data comparable across dates.

Typical survey

LiDAR flight over the full site polygon with on-site geodetic control, repeated per stage.

Deliverables

  • DTM and contours
  • Cut and fill volumes
  • Period comparison
  • Classified cloud

05 WHY LiDAR

Measure what imagery alone cannot show.

The value is not only in the flight: it is in the spatial dataset that remains available afterwards.

Conventional site information

  • Limited visibility of the site
  • Point-by-point manual measurements
  • Difficult access on complex terrain
  • Slower coverage per surface area
  • Less spatial detail recorded
  • Re-measuring requires returning to the field

Drone LiDAR

  • Dense 3D information across the area
  • Digital measurements on the model
  • Captures relief and hard-to-reach zones
  • Broad coverage in a single operation
  • Detailed, classifiable spatial record
  • The dataset is reused without flying again

LiDAR provides a richer spatial dataset from which multiple measurements and products can be derived. The right method for each project depends on scope, required tolerance and site conditions.

Returns beneath vegetation

Unlike photogrammetry, which reconstructs only what the camera can see, LiDAR pulses can pass through canopy openings and record ground returns. That makes terrain modeling possible in vegetated areas.

08 HOW WE WORK

We handle the technical complexity.

You define what needs to be measured; we take care of the rest of the process through delivery.

  1. Tell us what you need

    We review the location, area, survey objective and the deliverables your team expects.

    Scope and proposal

  2. Plan the flight

    We define altitude, overlap, target density and on-site geodetic control, accounting for relief, access and any applicable authorizations.

    Flight plan and control

  3. Capture the data

    Field operation with the DJI Zenmuse L3 sensor and GNSS/IMU trajectory logging. We verify coverage and quality before leaving the site.

    Field operation

  4. Process the LiDAR

    Trajectory computation, flight-line adjustment, filtering, point classification and quality control against check points.

    Office and quality control

  5. Deliver the results

    Files delivered in the agreed formats, with a technical report and a review session so your team can start using them immediately.

    Documented delivery

09 QUALITY & COMPLIANCE

Documented work from start to finish.

Every survey follows repeatable procedures and is delivered with its technical report.

  • Professional data acquisition

    Every flight is planned with documented parameters: altitude, overlap, target density and on-site geodetic control. Nothing is left to on-the-spot judgement.

  • Structured deliverables

    Consistent naming, open formats and a declared coordinate system in every file. Your team can open the data without depending on us.

  • Survey documentation

    Technical report with flight parameters, control points, processing method and quality-control results. The data is traceable.

  • Repeatable workflows

    Follow-up flights use the same control and the same parameters, so two deliveries from different dates are genuinely comparable.

  • Client-ready outputs

    Files arrive referenced to your project coordinate system and tested in the software where they will be used, not only in ours.

  • Project confidentiality

    Site information belongs to you. We do not publish locations, drawings or identifiable project data without written authorization.

10 FREQUENTLY ASKED QUESTIONS

Before you request a quote.

Not seeing your case? Describe it in the form and we will review it with you.

A laser sensor mounted on an unmanned aircraft emits pulses toward the ground and measures each return. Combined with the aircraft position and orientation, every return becomes a point with X, Y, Z coordinates. The result is a georeferenced point cloud describing the three-dimensional shape of the site.

To obtain terrain and surface models, contours, cross sections, volume calculations, documentation of existing conditions and progress comparisons between dates. Because it is a complete spatial dataset, several of these questions can be answered later without flying the site again.

We work with open, industry-standard formats: LAS and LAZ for point clouds, GeoTIFF for raster models, DWG, DXF and SHP for vectors, and PDF for reports. The exact package is defined in the proposal according to project scope.

It depends on platform flight time, authorized altitude, relief and the required point density. Large areas are covered with several flight sessions tied to the same geodetic control. With the location and approximate polygon we can estimate how many sessions are needed.

The work is split between field and office. Field time depends on area, access and weather; processing depends on data volume and the level of classification required. Every proposal includes an estimated timeline for both stages.

Yes. The calculation is performed on the surveyed surface against a base defined with you: natural ground, a reference plane or a previous survey. The report documents the method, the base used and the assumptions so the result is auditable.

LiDAR pulses can pass through canopy openings and record ground returns, which photogrammetry cannot do because it only reconstructs what the camera sees. How many ground returns are obtained depends on canopy density and flight parameters; on heavily vegetated sites the flight plan is adjusted to increase the chance of penetration.

Yes. The georeferenced, classified cloud is part of the deliverables, together with the metadata file documenting the coordinate system and survey parameters.

Yes. We deliver in formats that CAD, BIM and GIS software read natively, referenced to the coordinate system your team specifies. If the project already has a defined system, we adopt it from the start to avoid later transformations.

The site location, approximate area, the objective of the survey and the deliverables you need. If you have the polygon, a previous drawing or the project coordinate system, the proposal moves much faster. With that we can estimate the flight plan and processing scope.
