A Survey dataset processes geotagged JPEG images into a high-resolution terrain model and orthophoto. Including AeroPoints or your own ground control/checkpoints produces measurement grade accuracy outputs.
- 10 or more geotagged JPEG or JPG files with unique names.
- AeroPoints flight or other ground control point data uploaded as .csv (optional).
Selecting photos for upload
After selecting your site and Survey as the dataset type, upload the photos files by dragging and dropping or using the Dropbox integration to select a connected Dropbox folder.
Before uploading begins, your photos are scanned for conformance with:
- File type
- Compatible geotags
- Unique name (max length 255 characters)
Once the selected files have been validated, a map will be appear with the location of your photos.
When all photos are displaying as expected, click Next to proceed.
Set the dataset name and dataset 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.
- In order to choose a time, click the time panel at the bottom of the date selector. When done, click elsewhere on screen to close the date selector dialog.
The dataset name is how this dataset will be referred to in the Viewer and is defaulted to the dataset date.
Click Next to proceed.
Elevation model filtering
Elevation model filters are used to remove undesired artifacts such as trees, buildings, and vehicles from the digital elevation model output.
As part of output configuration you can select from three available filter settings, depending on the requirements for your model:
- Does not apply any automated filtering.
- Useful for producing an "as is" terrain model without removing objects like structures or vegetation that can interfere with measuring specific volumes.
2. Standard filter
- Applies a filter that removes perpendicular structures like buildings, vehicles, plant, and equipment from the terrain model.
- Useful for datasets focused on measuring stockpile volumes as it removes small foreign objects like plant and equipment without potential smoothing of the stockpile that may occur if using a harsher filter.
3. Harsh filter
- Applies a harsher filter with the purpose of producing a "bare earth" elevation model.
- Best for flatter sites where the bare earth level is critical.
- This setting can occasionally affect stockpiles or pit walls.
- Useful for sites with significant interference from foreign objects such as vegetation and vehicles.
This pane shows a list of the output files that will be produced as part of the the dataset. Files can be downloaded individually, where required, from the Viewer.
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.
Please read this article to learn more about the configuration for each of these options.
The next page is a summary of the details and the processing outputs which we will create on your new dataset.
Each card can be clicked in order to return to the relevant section for revision.
Once you click Submit, your request will be finalized and your files will begin uploading.
Once submitted, you can track the progress of the upload of your files. Do not close the window or navigate away from this page, or your upload will be cancelled.
If your internet connection is interrupted, a message will be displayed as 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.
An email will be sent to all Propeller users with view permission on your selected site once processing has completed.
