How Innovative Methods Reduce Environmental Impact and Improve Efficiency
Modern infrastructure in Africa demands precision, speed, and environmental responsibility. Through sustainable surveying practices, Trail Surveys is reshaping how data is collected and delivered—reducing on-site disturbance, improving accuracy, and supporting greener project outcomes.
What Are Sustainable Surveying Practices?
Sustainable surveying practices refer to techniques and technologies that minimise environmental impact while maintaining high accuracy and efficiency. This approach combines remote sensing, drone mapping, LiDAR, and GIS to collect detailed spatial data with reduced ground access, lower emissions, and minimal site disruption.
By applying these methods, surveyors can generate precise terrain and environmental data without invasive or resource-intensive fieldwork.
Low-Impact Techniques Driving Change
1) Drone and Aerial Surveys
Trail Surveys uses drone technology to capture high-resolution imagery and digital terrain models. This reduces the need for extensive on-site activity, cutting both fuel use and emissions.
2) LiDAR and 3D Laser Scanning
Airborne and terrestrial LiDAR scans allow surveyors to map vast areas quickly without disturbing vegetation or soil. These datasets provide detailed elevation and topographic information critical for planning roads, mines, and infrastructure responsibly.
3) GNSS Control and Smart Networks
Advanced GNSS control techniques shorten field time by optimising survey reference points. This limits travel, enhances accuracy, and increases safety by reducing staff exposure in challenging terrain.
4) GIS Integration and Data Reuse
Sustainability is also achieved through smarter data management. GIS mapping consolidates terrain, cadastral, and environmental layers into one digital environment, reducing duplication and improving decision-making across a project’s lifecycle.
Benefits of Sustainable Surveying Practices
- Reduced Environmental Impact: Minimises clearing, emissions, and ground disturbance.
- Improved Safety: Less time in remote or hazardous areas.
- Greater Efficiency: Faster data acquisition with lower operational costs.
- Enhanced Accuracy: Advanced sensors ensure precision even in complex terrain.
- Data Longevity: Digital datasets can be reused for future planning and environmental monitoring.
