LiDAR survey data your engineers can design on

We capture sites, corridors and regions with drone, aircraft, vehicle and tripod LiDAR, then deliver classified point clouds, terrain models and CAD drawings checked against survey control. Based in Langebaan, working across South Africa.

Four capture platforms, matched to the size of the job

We pick the platform from the area, the accuracy you need and the site conditions. Larger projects often combine two, such as drone coverage with mobile scanning on the roads.

Static site scanning

Buildings, plants and structures

Tripod laser scanning for interiors, plant rooms and assets where every surface needs to be measured.

Add LiDAR to your survey practice

We partner with survey firms and drone operators who want to offer LiDAR without investing in new software, training and a long learning curve. You keep the client, your team and your equipment. We bring the LiDAR expertise and return finished datasets ready to hand over.

  1. You win the jobQuote LiDAR work with confidence. We help you scope the deliverables and accuracy.
  2. Capture it your wayFly your own drone and send us the raw data, or we handle the capture for you.
  3. We process and checkClassification, surface modelling, CAD extraction and an accuracy check against control.
  4. You deliverFinished datasets in your client's coordinate system and formats.

StrataSwift: process LiDAR in-house

Prefer to do the processing yourself? StrataSwift is a Windows desktop application from GeoSwift. It takes aerial LiDAR and photogrammetry from raw flight strips to classified point clouds, contours, orthomosaics and TMH11 CAD drawings, all in one app. Your point clouds stay on your own PC.

  • Open the whole job as one point cloud, with no manual tiling
  • Flight line matching and control fitting, with a report of every change
  • CAD drafting directly on the laser points, with TMH11 cells and DXF or DGN export
  • Split heavy jobs across spare office PCs

Launching 15 January 2027.

One capture, every product your team needs

A single survey becomes several datasets. Here is the same road intersection as a point cloud, a terrain model, contours and a finished CAD drawing.

Point cloud of a road intersection
Triangulated terrain model of the same intersection
Contour lines of the same intersection
CAD drawing of the same intersection

Classified point cloud: every LiDAR return, coloured and classified into ground, buildings, vegetation and more.

  • Point cloudsClassified LAS/LAZ to ASPRS classes, colourised from imagery.
  • Terrain modelsDTM and DSM surfaces, contours and slope products.
  • OrthomosaicsGeo-rectified imagery, down to 1 cm on drone projects.
  • CAD and GISDWG/DXF drawings, TMH11 road surveys, asset and feature layers.
  • Survey reportMethod, calibration and accuracy checks against ground control.

Delivered in your project's coordinate system, including local datums and national grids. Formats: LAS/LAZ, GeoTIFF, DWG/DXF, SHP and GIS-ready layers.

How a project runs

The same four stages on every job, from a single building to a regional programme.

  1. Scope

    We agree objectives, accuracy targets, formats and timeline, then handle access approvals, safety files and flight permissions.

  2. Capture

    The right platform goes to site, tied to GNSS survey control and checked on the ground before we leave.

  3. Process

    Trajectory refinement, strip adjustment, classification and manual QC of every terrain surface.

  4. Deliver

    Packaged datasets, drawings and a survey report, with support while your team puts them to work.

Frequently asked questions

What areas do you cover in South Africa?

We deliver geospatial and survey services across South Africa, with project planning tailored to site access, terrain, and operating requirements.

What deliverables can we expect from a survey?

Typical deliverables include classified point clouds, DTM/DSM terrain models, orthomosaics, contours, and GIS/CAD-ready datasets aligned to your specification.

Which survey method is best for my project?

We select the most suitable platform based on area size, required accuracy, and site conditions. Options include drone, manned aircraft, mobile corridor mapping, and static site scanning.

How do you ensure data quality?

Our workflow includes calibration checks, trajectory refinement, strip adjustment, classification, and QA verification against project control to ensure reliable outputs.

How accurate is LiDAR and what controls it?

Accuracy depends on platform, flight height, speed, GNSS/IMU quality, ground control, and surface conditions. We confirm achievable accuracy during scoping and validate against control during QA.

What point density do I need?

Point density is driven by the smallest features you need to model and the required surface confidence. We recommend densities based on your design tolerances and intended outputs.

Can LiDAR see through vegetation?

LiDAR can penetrate gaps in vegetation, allowing ground points to be classified, but dense canopy reduces ground visibility. We plan flight parameters to improve ground returns where possible.

How do LiDAR and photogrammetry differ?

LiDAR measures distance directly and performs well in low-texture areas and vegetation. Photogrammetry relies on image matching and works best on textured surfaces. We often combine both for best results.

What coordinate systems and datums do you support?

We deliver in the coordinate reference system required by your project, including local survey datums and national grids. We confirm the CRS during scoping to avoid any rework.

What file formats do you deliver?

Common formats include LAS/LAZ point clouds, GeoTIFF orthomosaics, DTM/DSM grids, CAD drawings, and GIS-ready layers. We align outputs to your specification.

How long does processing take?

Turnaround depends on area size, density, and required deliverables. We provide a schedule during scoping and can phase deliveries for large projects.
