Topographic surveys

The challenge

Topographic survey teams must capture highly accurate terrain data across large sites while navigating complex airspace, evolving site hazards and tight project timelines.

Consistency is critical — even small deviations in planning or execution can result in inaccurate models, rework or delays.

Manual RAMS creation, inconsistent pilot workflows, and fragmented flight logs make it difficult to deliver repeatable, defensible survey outputs across multiple locations or surveyors.

The solution

heliguy.io provides a structured operational framework tailored to the precision demands of topographic surveys.

heliguy.io enables survey teams to:

• Generate hazard-aware RAMS that account for slopes, access constraints, terrain obstacles, and site-specific limits.
• Use standardised mission templates to replicate flight grids and maintain consistent capture geometry across sites.
• Automatically retrieve DJI flight logs to secure metadata critical for elevation accuracy and validation.
• Operate offline in rural or upland locations, supporting surveys where connectivity is limited.
• Monitor live environmental conditions to avoid weather that could distort terrain capture.

Results

With heliguy.io, topographic survey teams can:

• Deliver consistent flight geometry and data capture for surface modelling and contouring.
• Reduce rework caused by capture variation across days, crews or locations.
• Maintain traceable metadata to support validation, audits, and dispute resolution.
• Operate confidently in remote environments with limited access or connectivity.
• Reduce administrative overhead and accelerate project turnaround.
