What is PLD (Payload Data) & How Does it Work?
Definition
PLD, or Payload Data, refers to the information collected by a drone’s onboard sensors or instruments during flight. This can include visual images, thermal readings, LiDAR point clouds, multispectral imagery, gas detection metrics, and more—depending on the payload installed. PLD represents the core output of drone missions and is critical in inspection, analysis, and reporting.
Usage
In industrial inspections, PLD is used to detect cracks, corrosion, heat loss, electrical faults, vegetation encroachment, or structural movement. Operators configure the drone’s payload—such as high-resolution cameras or thermal sensors—to collect mission-specific data during infrastructure surveys, energy assessments, environmental monitoring, and other field operations.
Relevance to the Industry
PLD is the foundation for making informed decisions in sectors like construction, oil and gas, utilities, telecommunications, and agriculture. The accuracy, resolution, and relevance of payload data directly influence the quality of inspections and the reliability of automated analysis using AI or machine learning. Effective PLD workflows also support compliance documentation, predictive maintenance, and asset lifecycle planning.
How Does PLD (Payload Data) Work?
Payload Data (PLD) is generated through a sequence of carefully orchestrated steps involving sensor activation, drone flight planning, data acquisition, and processing. The goal is to gather accurate, mission-specific data that can be transformed into actionable insights for inspection or analysis. Here’s how PLD works during typical industrial drone operations:
Payload Configuration and Calibration
Before the mission begins, the drone’s payload—such as a camera, thermal imager, LiDAR scanner, or gas sensor—is mounted, connected, and calibrated. Each sensor type has specific setup parameters to ensure accuracy (e.g., focus settings for cameras, temperature range for thermal sensors).
Flight Planning and Payload Settings
Operators define the flight path using mission planning software, configuring altitude, speed, overlap, and scanning patterns. Payload settings like capture frequency, sensor resolution, and trigger points are also programmed to match the objective—whether capturing fine structural details or wide-area thermal readings.
Data Acquisition During Flight
As the drone follows its programmed route, the payload actively collects data. Cameras take high-resolution images at set intervals, thermal sensors measure surface temperatures, and LiDAR scanners capture 3D spatial points. All captured data is time-stamped and geotagged using onboard GPS or RTK positioning systems.
Data Storage and Transmission
The raw payload data is stored locally on the drone’s onboard storage or streamed in real time to ground control (if bandwidth allows). This ensures redundancy and facilitates immediate review if needed.
Post-Processing and Analysis
After the flight, PLD is offloaded and processed using industry-specific software platforms. This includes:
Stitching photos into orthomosaics
Rendering 3D models from LiDAR
Highlighting anomalies in thermal data
Generating volumetric or dimensional measurements
Running AI-based detection for cracks, corrosion, or vegetation overgrowth
Data Interpretation and Reporting
The processed payload data is compiled into reports, inspection maps, or maintenance plans. These outputs are then shared with engineers, project managers, regulators, or clients to inform next steps—such as repair, compliance action, or long-term monitoring.
Through the combination of smart payloads, mission planning, and intelligent data analysis, PLD transforms drone flights into meaningful outputs that save time, increase safety, and enhance decision-making in industrial environments.
Example in Use
“The inspection drone collected payload data using both a zoom camera and a thermal sensor, revealing a potential hotspot on the transformer assembly.”
