Service overview

3D site data

Photogrammetric processing can convert controlled aerial imagery into dense 3D point clouds, meshes and terrain data for suitable sites.

These datasets can support measurement, visualisation, surface extraction, site review and downstream CAD or engineering workflows depending on the project requirements.

Point cloudsDense 3D spatial datasets generated from overlapping aerial imagery.
3D mesh / modelTextured spatial representation of visible site surfaces and structures.
Terrain processingExtract or derive surface information for compatible survey and engineering workflows.

Questions

3D Site Models & Point Clouds FAQ

Is a photogrammetric point cloud LiDAR?

No. A photogrammetric point cloud is generated from overlapping camera imagery. LiDAR is a different acquisition technology.

What can a 3D site model be used for?

Typical uses include visualisation, measurement, terrain processing, surface extraction, site records and supporting CAD or engineering workflows.

What file formats can be supplied?

Depending on the workflow, point-cloud and spatial data can be supplied in formats such as LAS, LAZ, E57, LandXML, XYZ, DWG or other agreed compatible formats.
