If you want to process data using the Propeller PPK Workflow, follow our instructions for PPK compatible DJI Drones, WingtraOne, or the Trinity F90+ drone. This article provides instructions on processing data with our standard dataset workflow.
The standard survey datasets process geotagged JPEG images into a high-resolution terrain model and orthophoto. Including AeroPoints or your own ground control/checkpoints produces measurement grade accuracy outputs.
To process a standard dataset, you must have the following:
- Ten or more geotagged JPEG or JPG files with unique names.
- AeroPoints flight or other ground control point data uploaded as .csv (optional).
From the Portal homepage, click the three dots on the site thumbnail on the home page and select Create new dataset.
Or, click on DATA PROCESSING, and select CREATE A NEW DATASET.
Choose the site from the dropdown menu to which you want to add data. Alternatively, you can also CREATE A NEW SITE from here.
Select Survey for the data type and click NEXT.
Next, upload the photo files by dragging and dropping them into your browser.
Your photos are validated against three categories and must pass these requirements to be properly processed.
|Your file collection
|Minimum of 10 images
|The drone camera is recommended
|Same aspect ratio
|Camera course alignment
|Single connected area
|The name is less than 255 characters.
|Minimum of 8 Megapixels.
We will describe the error if a warning is raised to help you fix the issue. If you choose to bypass the error, you must agree to acknowledge the error and understand that the accuracy of your dataset may be affected. Click NEXT to proceed.
Once the selected files have been validated, a map will appear with the location of your photos.
When all photos are displaying as expected, click NEXT to proceed.
Add the Dataset details, including the dataset name and capture date.
- The capture date/time will determine where the dataset lies on the timeline view and is defaulted from the capture time of the first submitted image.
- To choose a time, click the time panel to the right.
The dataset name is how this dataset will be referred to in the Platform and is defaulted to the dataset date.
Click NEXT to proceed.
Ground Control Points / Checkpoints
There are four options for adding ground control and/or checkpoints when submitting a survey:
- Adding an AeroPoint flight,
- Uploading a CSV file with ground control points,
- Adding both an AeroPoint flight and CSV, or
- Not adding ground control.
Elevation model filtering
Elevation model filters remove undesired artifacts such as trees, buildings, equipment, and vehicles from the digital elevation model output.
You can select No filter or from the other available filter settings as part of the output configuration.
We recommend using either No Filter or Equipment filters and combining this tool with Terrain Cleanups to ensure you only remove items that would affect your measurements.
This page lists the output files produced as part of the dataset. Files can also be downloaded individually from the Platform.
Click NEXT to proceed.
The following sections summarize the details and the processing outputs we will create with your new dataset.
Each card can be clicked to return to the relevant section for revision.
Once you click SUBMIT, your request will be finalized, and your files will begin uploading.
General information about the dataset you are submitting, including:
- Site name
- Date and time flown
- Total gigapixels and photos
- Type of upload
Type and number of GCPs and checkpoints
- Files included in the platform
- Downloadable files
Quality assurance settings
This guides how many Quality Assurance (QA) checks are made on your survey. Generally, the stricter the chosen QA, the longer the turnaround time.
Total number of credits used to process your data
Once submitted, you can track the progress of the upload of your files.
Do not close the window or navigate away from this page; your upload will be canceled.
If your internet connection is interrupted, a message will be displayed below. Leave your browser window open and your computer running, and the upload will automatically resume when possible.
Once your files have completed uploading, you will see the page below. It is now safe to navigate away from the page. Alternatively, use the buttons to access the Viewer or create another dataset.
Once processing has been completed, an email will be sent to all Propeller users with view permission on your selected site.
