How to upload and process DJI L1 LiDAR data with DroneMaps

To begin, you must have completed your capture mission. The steps to complete your capture mission can be found at How to create a new mapping mission with DJI PILOT

Required files for processing

Before we dive into the step-by-step process of uploading and processing your DJI L1 LiDAR data, let's ensure you have everything you need. For DJI L1 LiDAR data processing, you'll need to have the following files ready:

• LiDAR Data (.LDR): These files are the heart of your LiDAR data, containing the raw point cloud information.
• LiDAR Calibration Data (.CLC): Essential for precise data processing, this calibration file ensures accuracy.
• LiDAR IMU Calibration Data (.CLI): Your LiDAR's IMU calibration data is crucial for achieving the best results.
• Inertial Navigation Data (.IMU): This data contributes to the accuracy of your LiDAR information.
• RTK Base Station Data (.RTB): RTK (Real-Time Kinematics) base station data adds another layer of precision.
• RTK Antenna Data (.RTK): Accurate RTK antenna data is vital for geospatial insights.
• Rod Arm Data (.RTL): These files provide essential information for your data processing.
• RTK Sub Antenna Data (.RTS): Ensure accuracy with the inclusion of RTK sub antenna data.

These files work together to create a comprehensive dataset ready for processing. Once you've gathered them, you're set to make the most of your DJI L1 LiDAR data with DroneMaps.

How to upload and process your DJI L1 LiDAR data

Processing your DJI L1 LiDAR data begins with uploading it to the DroneMaps platform. DroneMaps simplifies the processing by automating the majority of settings, significantly reducing the need for manual adjustments.

Note: RTK (Real-Time-Kinematics) data must be present in your dataset to process correctly and achieve accuracy. For detailed information on RTK, simply scroll down to the bottom of the page to explore our comprehensive tips and best practices section.

Step 1: Accessing the upload interface

• Log in to your account on DroneMaps.
• Once you've successfully logged in, you will be directed to the dashboard. Here, you will see the "Process" tab located at the top of the screen. Click on it to access the Upload interface.

Step 2: Uploading your data

To initiate the upload process, you have two options:

1. Drag and Drop: Simply drag your prepared DJI L1 LiDAR Mission folder from your computer and drop it onto the designated area within the processing interface.

2. File Selector: Alternatively, you can click on the file selector area to open your computer's file explorer. Browse and select the prepared Mission folder containing your DJI L1 LiDAR data.

Note: The time required for the upload may vary depending on the size and quantity of your data. If you are having issues with uploading refer to the specific files required for LiDAR processing.

Step 3: Initiate the upload process

Once you've imported your dataset, you'll be greeted with an overview of the geographical area covered by your mission. Here's how you can kickstart the upload for processing:

1. Customize Your Dataset Name: On the left-hand side, you'll spot an interactive field for giving your dataset a distinctive name. Provide a name that resonates with your project, making it easily recognizable.
2. Select Your Site: Just below the naming field, you'll find the "Select Site" option. Choose the specific site where you intend to process this dataset. This step ensures your data aligns perfectly with the intended location.
3. Launch the Upload: To set your dataset on its processing journey, simply click the "Upload" button located at the bottom left corner.

Tips and Best Practices

RTK Limitations & Known Issues

Keep a close watch on RTK Fix during your flights, aiming for it to remain above 85%. Maintaining a strong RTK link quality is vital for accurate calibration and reconstruction processes. Lower RTK Fix percentages, below 85%, may lead to processing challenges. For L1 Type Datasets, you can expect Point Clouds as the primary output. This format best suits specific project needs.

Check Your Internet Connection

Ensure you have a stable and high-speed internet connection during both the upload and processing phases. A reliable connection prevents interruptions and speeds up data transfer.

Monitor Processing Progress

To stay informed about the progress of your data processing, simply navigate to the browse screen on our platform. Here, you can easily track the status and review the results. Monitoring the processing progress is essential for promptly addressing any issues or errors.
