Organizational processes regarding collection and analysis, as well as the application of spatial data, have been changed significantly by the development of drone technology. The way organizations collect data (at a lower cost and with a greater degree of accuracy) has changed compared to traditional means of collecting data. The use of sophisticated sensors, cameras, LiDAR systems, and GPS technology allows drones to collect data from across large geographic regions with a high resolution that is congruent to ground-level data accuracy, regardless of whether the land is used for construction, agriculture, mining, or environmental monitoring.
As more industries begin to implement unmanned aircraft systems (UAS), understanding how to collect drone data, the types of applications for drone-collected data, and best practices will allow organizations to gain maximum benefit (operationally) from drone legislation while ensuring the quality of the data collected.
What Is Drone Data Collection?
Drone data collection is the process of capturing and collecting geospatial, visual, thermal, or environmental information from UAVs. Most often, drones fly definable routes while capturing data from specialized sensors, which can be processed to derive actionable insights.
Examples of collected drone data are:
Aerial imagery captured at a high resolution
Orthomosaic maps
Digital elevation models (DEMs)
Three-dimensional terrain models
Point cloud data sets
Thermal imaging
LiDAR
Vegetation health indices
Organizations utilize the data collected from drones to assist them in their decision-making, asset management, and field operations processes.
How Drone Data Collection Works
Mission Planning
The operator will determine:
Boundaries of the survey area
Altitude at which the drone will fly
Required overlap between images taken of the ground
Preferred flight path
Sensor settings
The location of ground control points (GCPs)
Thorough content planning supports the creation of comprehensive coverage and accurate data collection.
Data Acquisition
The drone follows its pre-programmed flight path while gathering imagery or sensor data, such as the following, depending on what is needed to complete the project:
RGB camera images
Multispectral sensor data
Thermal camera images
LiDAR scanner data
Hyperspectral sensor data
Data Processing
The data that is collected is processed using photogrammetry or LiDAR post-processing software to create the following, which can be used to conduct an analysis on the data and report relevant information back to clients:
Orthomosaics
3D models
Digital Surface Models (DSM)
Digital Terrain Models (DTM)
Point clouds
Analysis and Reporting
The processed data is analyzed to identify trends, determine changes, measure distances/areas, and provide relevant information that can assist in making operational decisions.
Drone Data Collection Methods that Can Be Used
Different types of data collection methods can be utilized based on the project and its goals. Below are five of the most widely used methods:
Photogrammetry
Photogrammetry creates an accurate map or 3D model by overlapping aerial photographs.
Advantages:
Cost-effective
High-resolution imagery
Great for large land areas
Creates detailed 3D reconstructions
Common Use Cases:
Land Surveys
Construction Monitoring
Urban Planning
Infrastructure Inspection
LiDAR Data Collection
LiDAR is the process of using laser pulses sent from the drone to the ground to measure distances.
Advantages:
Provided a high level of accuracy
Can penetrate vegetation
Able to map complex terrain
Creates large amounts of point cloud data
Common Use Cases:
Forestry Management
Topographic Surveys
Utility Corridor Mapping
Flood Risk Assessment
Thermal Imaging Surveys
Thermal sensors detect the heat emitted or reflected back from an object.
Advantages:
Non-Invasive Inspections
Identifies potential issues that can't be seen visually
Works in low light
Common Use Cases:
Solar Panel Inspections
Energy Audits in Buildings
Electrical System Inspections
Search and Rescue Applications
Multispectral Data Collection
Multispectral cameras can capture information from wavelengths beyond the visible spectrum.
Advantages:
Used to determine the health of vegetation
Assists in precision agriculture
Identifies crop stress early
Common Use Cases:
Crop Monitoring
Irrigation Management
Soil Analysis
Environmental Assessment
Benefits of Drone Data Collection
Increased Efficiency
Surveys conducted using a drone can survey hundreds of acres in a much shorter time than was traditionally done using ground-based equipment.
Increased Safety
Remote collection of data reduces personnel working in hazardous areas by eliminating the need to access them physically.
Cost Savings
Ending an automated flight and faster collection of data due to the use of drones will decrease the number of people needed for labour and the cost of operations.
Increased Accuracy
Today’s drones are designed with real-time kinematic (RTK) and post-processing kinematic (PPK) positioning systems, which can produce accuracies within centimetres.
Improved Decision-making
Real-time data and images allow organisations to make better strategic decisions because all the information is readily available.
Future Trends in Drone Data Collection
The Drone Industry is Changing Rapidly and Only Getting Faster With the Development And Deployment Of:
Artificial Intelligence (AI)
Machine Learning Analytics
Autonomous Flight Systems
Real-Time Cloud Computing
Digital Twin Technology
Edge Computing
These advances produce quicker data analytics, automated insight generation, and advanced forms of airborne intelligence.
The continued enhancement of drone hardware and software means organizations can realize even higher levels of accuracy, productivity, and scale within their respective data collection operations.
Drone Data Collection Has Been Critical In Support Of Modern Surveying, Mapping, Inspection, And Monitoring Activities. Organizations Utilizing Technologies Like Photogrammetry, Lidar, Thermal Mapping, And Multispectral Sensing Are Able To Collect Very Accurate Data And Increase Safety While Reducing Costs.
Regardless Of The Applications, Be They Construction, Agriculture, Mining, Environmental Management, Or Infrastructure Inspection, The Aggregate Value Derived From Aerial Based Data Collecting Capabilities Yields Actionable Insights To Help Make Better Decisions. Adhering To Industry Best Practices When Undertaking The Activity, Such As Mission Planning, Sensor Selection, Weather Analysis, And Regulatory Compliance, Are Key To Guaranteeing Successful Project Outcomes And Maximizing Value Received From Aerial Data.
The Rapid Developments Associated With Drone Technology Will Result In It Continuing To Play An Increasingly Important Role Within Geospatial Intelligence And Operations Optimization For Many Industries Around The World.
