Topographic survey

Topographic survey with 3D laser scanning

We capture the exact geometry of terrain, urban developments, slopes and infrastructure with millimetre precision. Delivery of DTM, contour lines, volumes and topographic plans.

Why traditional surveying falls short

A total station captures singular points: it leaves out most of the terrain geometry.

Measuring slopes, roofs or hard-to-reach areas is slow and risky with traditional methods.

Volume calculations based on cross-sections are approximate, not densely sampled.

Integrating topographic data with architectural or BIM plans requires manual reconciliation work.

Laser surveying: the entire terrain, not just a few points

3D laser scanning captures millions of points per station. Every square metre of terrain is documented with millimetre precision.

3D laser scanning of terrain and built elements in a single day (Trimble X7).

GNSS georeferencing to integrate with official cartography and land registry.

Digital terrain models (DTM) and contour lines at the density the project requires.

Cut/fill volume calculations with centimetre precision.

Direct integration with BIM workflows and urban development, civil engineering and building projects.
