Painpoints

Absence of frequently updated stockpile measurements can lead to project delays and inaccurate resources supply.
Inefficient walk-based methods results on higher labor cost and time.
Stockpile manual measurements accuracy can be compromised by human errors.

Advantages

Generate updated Stockpile Measurement with Point Cloud Data at any time.
Cut field work time with efficient drone-based data collection.
Ensure data quality and consistency with repeatable mission flights.

Workflow

Data Collection:
- – Design a 2D map mission for consistent orthomosaic data acquisition.
Data Processing:
- – Utilize DJI Terra for processing, generating a high-accuracy dense Point Cloud from the collected data.
Data Analysis:
- – Measure stockpile volumes efficiently with DJI Terra. Alternatively, import the Point Cloud data directly into third-party software for comprehensive cut and fill analysis.

Automated Routine Stockpile Measurement Solution

The DJI Dock 3 allows you to automate recurrent stockpile measurement task effortlessly. Schedule remote data collection flights and upload collected data to DJI FlightHub 2 or your preferred Earthwork Software for timely project progress checks.
