Aerial & 3D Data
Point Clouds & 3D Models
The measured surface, as data rather than a picture. Issued in the open formats your software already reads, so you can measure it, section it, colour it and take it into your own workflow without being locked to ours.
Typical accuracy · Depends on method: survey-grade control delivers millimetre-class data, aerial reconstruction delivers centimetre-class.
When you need it
- →You need to measure from the as-is condition of a structure.
- →A remodel needs the existing fabric captured accurately first.
- →Repeated surveys need to be compared cloud to cloud.
- →You want a deliverable that will still be useful in five years.
What you get
- Point cloud in E57, LAZ or LAS
- ASCII XYZ or CSV where the pipeline needs it
- Mesh model in OBJ, STL or PLY
- BIM-ready export in IFC where applicable
- Separate layers per epoch or per survey method
How it runs
- 01
Agree the format and the deliverable spec before capture.
- 02
Capture by the method that suits the site and the accuracy you need.
- 03
Registration, classification and quality check against control.
- 04
Issue with a written statement of what the data is and is not.
- Horizontal control
- ±10mm typical
- Vertical control
- ±8mm typical
- Datum
- OSGB36 · EPSG:27700
- Area covered
- Norfolk base · 6 regions
Questions we get asked
Why not just send a PDF?
A PDF is a picture of a measurement. A point cloud is the measurement. If you ever need to answer a new question about the site, the cloud answers it and the PDF does not.
Which software can open these?
The formats are industry standard and open in almost all mainstream survey, civil, structural and BIM packages. If your software is unusual, tell us and we will deliver to its spec.
