UAS-Based Geohazard Assessments

Safer, Faster Aerial Data for Better Geohazard Decisions

UAS-Based Geohazard Assessments

GeoStabilization International delivers UAS-Based Geohazard Assessments to support safer planning, clearer risk evaluation, and stronger mitigation design across Canada. Unmanned Aerial Systems (UAS), commonly referred to as drones, allow our engineers and geologists to collect high-quality spatial data in steep, unstable, remote, or access-limited terrain, without putting crews at unnecessary risk.

From mountain transportation corridors in British Columbia to erosion-prone slopes and infrastructure networks across Alberta, Ontario, and Atlantic Canada, GSI uses UAS data before, during, and after construction to improve site understanding and support confident decision-making.

Why UAS Matters for Safety and Performance

Using UAS technology improves both safety and efficiency, especially where terrain or exposure makes ground-based surveys difficult.

Key benefits include:

• Safer data collection, reducing time spent on unstable or high-angle slopes 
• Faster turnaround, helping teams move from investigation to design sooner 
• Better design inputs, reducing uncertainty with accurate surfaces and measurements 
• Clear visuals for stakeholders, supporting alignment and decision-making 
• Better network planning, using wide-area data to prioritize maintenance and mitigation 

UAS data also integrates well with GSI’s mitigation services, including soil nailing, mesh/netting, rockfall systems, shotcrete, micropiles, drainage, retaining systems, and critical slope monitoring, supporting reliable performance throughout the project lifecycle.
