Modern mapping: a digital twin of your site

Drone-based surveying solutions: capture, processing and deliverables in a single cycle.
Orthomosaics, digital terrain models and topographic surveys for design and cadastral work.

Absolute accuracy
down to 1 centimetre

RTK STATUS: FIXED
PRECISION: 1 CM
GSD: 1.2 CM/PX

02 / Positioning

A shift in approach: from spot measurements
to full coverage

Traditional methods

Surveyor taking measurements by hand with a survey pole

!Slow data collection that depends on the human factor.

!Gaps and blind spots across difficult terrain.

!Limited access to hazardous and hard-to-reach areas.

Drones + RTK

Aerial survey area mapped out over the terrain

✓Speed: up to 100 hectares surveyed in a single day.

✓Coverage: continuous scanning — millions of points, not hundreds.

✓Safety: hazardous assets surveyed without contact.

03 / Technology standard

Real-time kinematics (RTK)

01RTK module: instant satellite correction of coordinates — horizontal and vertical error no more than 10 mm.

02Minimal ground control: less dependence on ground control points, field work 3× faster.

03Validation: deliverables prepared to meet cadastral registration requirements and the relevant design standards.

04 / Deliverable 01

Orthomosaic production

GSD down to 1 cm / pixel

01Absolute geometry: photographic quality with the mathematical accuracy of a map.

02Inventory: cadastral registration, detection of encroachments and overlapping boundaries.

03Monitoring: as-built records that keep contractor work under control.

05 / Deliverable 02

Digital terrain and surface models (DTM / DSM)

Point cloud from laser scanning of the terrain

Point cloud: raw survey data — millions of measurements.

TIN mesh: a terrain surface ready for calculations and design.

3D model: a textured twin of the site for work and presentations.

01Data density: thousands of points per square metre — no blind spots.

02Slope design: analysis of drainage, sunlight and vertical planning.

03Volume calculation: cut and fill of earth masses with an error of < 1%.

06 / Deliverable 03

Topographic surveying in a new format

01Every scale: plans at 1:500, 1:1000 and 1:2000.

02Vectorisation: point clouds converted into standard drawings with no loss of quality.

03Combined approach: aerial survey plus ground checks of underground utilities.

07 / Outcome

Seamless integration
into your business processes

01Cadastral engineer: land surveying and boundary registration.

02Builder: control of earthworks and volumes.

03Architect: BIM and the master plan.

04Investor: budget and progress monitoring.
