Engineering-Grade Mapping, Measurements & RTK Spatial Data

Survey-grade drone maps, RTK-validated spatial data, and volumetric stockpile measurements that form digital twins, reducing rework, confirming costs, preventing disputes, and limiting commercial risk with defensible spatial validation.

The Challenge: Inaccurate or Inconsistent Data

Inaccurate or inconsistent spatial data introduces measurable commercial risk across contracts, certification and lifecycle governance.

Common consequences include:

• Quantity and volumetric ambiguity

• Delayed approvals and certification cycles

• Contract disputes and variation claims

• Rework due to inconsistent baselines

• Fragmented asset records

• Limited lifecycle comparability

The Cost of Fragmented Spatial Data

Industry studies show:

14% of global construction rework is linked to poor data management

80% of large projects exceed budget

Data silos drive avoidable delay, duplication and claims exposure

FAQ's

How accurate is your spatial data?

+

We deliver survey-grade accuracy using RTK/PPK GNSS workflows validated with ground control points. Typical absolute accuracy is 2-3cm horizontal and 3-5cm vertical, meeting Australian survey standards for engineering and commercial applications.

What coordinate systems do you deliver in?

+

All data is delivered in GDA2020/MGA2020 as standard. We can also deliver in project-specific coordinate systems, local grids, or legacy datums (GDA94) on request. Coordinate system documentation is included with every deliverable.

How often should we capture spatial data?

+

This depends on your project dynamics. Active earthworks sites typically benefit from weekly or fortnightly captures. Construction flythrough weekly for project progress and variation reporting. Stockpile audits may be monthly or quarterly. We structure programs around your reporting cycles and commercial milestones.

How does this compare to traditional ground survey?

+

Our methods capture 10-50x more data points per site visit with comparable or better accuracy for surface measurements and provide accurate DSMs and DTMs. Traditional survey remains superior for sub-centimetre point accuracy on specific features such as boundaries, but for area-based measurements (volumes, surfaces, progress), drone-based spatial capture is faster, more comprehensive, and more cost-effective. We recommend using licenced surveyors when cadastral data is required, as it must be certified specifically by a surveyor.

How much does a survey-grade drone survey cost in Australia?

+

Survey-grade drone surveys in Australia typically represent a 40-60% cost reduction compared to traditional ground survey methods for equivalent accuracy. Our RTK-enabled capture with Emlid RS3 ground control achieves plus or minus 2cm positional accuracy, which satisfies engineering design and as-built verification requirements. For ongoing programs with multiple sites, we offer structured pricing that reduces per-site costs further. Every engagement begins with a free scoping call to define your accuracy requirements and deliverables before quoting.
