Click the “Upload Data” button at the top right hand side of the Viewer.
Select ’Start’ to begin the upload process.
Select at least 10 source photos from your computer. All photos must have compatible geotags.
The next screen will alert if these requirements have been met.
Our image processing software requires at least 10 photographs with approximately 70-80% overlap to reconstruct a 3D model. The uploader checks that you have at least ten photographs with geotags, so you won’t get a warning about insufficient overlap until later in processing.
All photos must have compatible geotags. This information is stored in the EXIF header data of the photographs. If you collected data with a drone that does not add geotag information to the photographs, you may need to use software like exiftool to add the geotag information back into the photographs, before you can upload data.
Choose the Site where you want to upload your dataset.
We recommend leaving the dataset name the same as the default, which is the date of the survey, taken from the file information attached to your photos.
Next you will be prompted to select an ’Ouput Profile’. An output profile is either a Survey or an Inspection. Surveys use the geotag information in your photos to produce a 3D model of your site which can then be queried for volume estimates, point surveys and line surveys.
Inspections also produce a 3D model of your site which can be visualised but does not include the same query options as a Survey. Inspections are usually faster to process.
In the future, requests to reprocess an Inspection as a Survey may incur an additional charge. So if you think you will need to query your model for point elevation, line surveys or volume surveys in the future, please select “Survey”.
The next step is to upload information about your ground control points.
If you are using AeroPoints, change “Select type” to “Propeller AeroPoints”
If you are not using any ground control, change “Select type” to “No GCPs or AeroPoints”
If you are using your own ground control points, you will be prompted to enter a CSV file with the coordinates and names of the GCPs. You will also need to enter details of the Coordinate Reference System and projection of the GCPs. It is important to get this correct because our manual data processing step requires correct coordinate reference system and projection information. If you are uncertain about the coordinate reference system and projection please check with your surveyor before uploading.
If you are using AeroPoints, please ensure that you have uploaded data from your AeroPoints and that it has been processed. You can process your AeroPoints in the AeroPoints Dashboard at <yoursite>.prpeller.com/p/aeropoints.
If you want to proceed without Ground Control Points, select ”No GCPs or AeroPoints” from the drop down menu.
You need to select the checkbox to acknowledge that your survey accuracy will be reduced without GCPs.
Make sure you leave your browser open while the Survey is uploading.
The confirmation screen indicates how long you should expect to wait for your survey to be finished processing.
There are a number of automatic processing steps that take time for our computers to process, as well as manual processing steps that may be required to correct errors that can arise when joining data from multiple flights, and potential errors resulting from the drone flight method.
If you used AeroPoints, we may include an estimate of the time required to collect correction data from our correction network.
The Service Level Agreement reported at the bottom of the confirmation screen is the timeframe within which we commit to processing your data and is calculated as follows:
- Survey baseline SLA: 24 h
- If ground control points were used: + 12h (manual input required)
- If AeroPoints were used, and at time of submission they were unprocessed, we need to wait for correction data: +48 h
- If data is submitted just prior to a weekend of public holiday, this time is included in the SLA estimate.
