What is Drone Surveying?
Drone surveying is a modern method of collecting geospatial data using unmanned aerial vehicles (UAVs), commonly known as drones. It's an efficient and cost-effective alternative to traditional surveying methods. By utilising off-the-shelf technology, organisations and projects can benefit from this cost-effective solution. Here's an overview of drone surveying:
Process:
A drone equipped with cameras and sensors flies over an area of interest
It captures high-resolution images and data from various angles
These images are then processed using specialised software to create detailed maps, 3D models, and other geospatial products
Key components:
UAV (drone)
High-resolution cameras (often including RGB and multispectral)
GPS/GNSS/IMU for precise positioning
Other sensors (e.g., LiDAR for laser scanning)
Data processing software
Applications in mining and construction:
Site planning and monitoring
Environmental impact assessments
Safety inspections
Progress tracking
Advantages:
Faster data collection compared to traditional methods
Access to hard-to-reach or dangerous areas
High accuracy and detail in data
Cost-effective for surveying large areas
Ability to frequently update data
Challenges:
Regulatory compliance (drone laws vary by country)
Weather dependencies
Need for skilled operators and data analysts
Drone surveying has transformed the field of geospatial data collection, offering a blend of speed, accuracy, and cost-effectiveness that is particularly valuable in industries like mining, construction, and environmental monitoring.
Modern drone surveys can regularly achieve centimetre-level accuracy when coupled with RTK/PPK workflows and GCPs/CPs (Ground Control Points/Check Points).
Drone surveying also allows for data integration and interoperability with other software’s and data formats. For example, GIS with data storage, analysis, and management, BIM for construction applications and planning, and AI/ML for automated feature extraction and change detection.
With years of flying and an experienced geospatial team, we can assist your projects and teams with drone surveying, GIS/remote sensing, stockpile calculations, quantity assessments, education, and more.
