Uploading High Accuracy Geotagged Photo Datasets


This article will guide you through the upload procedure for high-accuracy datasets that have been geotagged using an RTK or PPK solution other than Propeller PPK
Please note there are different steps for uploading a PPK survey dataset with a compatible DJI droneWingtraOne, Autel EVO, or Quantum Trinity F90+.

Prerequisites

  • You know the coordinate reference system of your site.
  • If you are using a local calibration, it has already been configured for the site.
  • You know the horizontal datum and vertical datum of your image geotags.

Uploading geotagged images

Upload your photos using the Survey option

Your photos are scanned for conformance in the following three categories. Photos must pass these requirements to be properly processed. 

Your file collection
Your drone
Individual images
10 image minimum Drone camera is recommended Compatible geotag
Same aspect ratio   Aspect ratio
Camera course alignment   Motion blur
Single connected area   ISO
Files contain high accuracy geotags   Name less than 255 characters
    Minimum 8 megapixels
For more information on these validations, please see our best practices for drone surveying

Once the photos have been validated, a map will appear with the location of your photos. Make sure that the map of the photos is in the area you surveyed. To let us know these are high-precision geotags, toggle on the Photos have high-accuracy geotags option. 

A word of caution—if you are unsure if your photos have been corrected already, do not turn on the toggle.
 
If you fly a P4R, M300, M350, or M3E using the real-time kinematic (RTK) mode turned on, the .bin and .MRK files should be removed from your upload.

To remove the .bin and .MRK files, click the trash can next to each file in the list of images in the uploader.

Provide your ground control used for the flights

As per the standard workflow, there are four options for submitting ground control:

  1. Adding an AeroPoint survey
  2. Uploading a CSV file with ground control points
  3. Adding both an AeroPoint survey and a CSV
  4. Not adding ground control
  5. Choose whichever ground control method is most appropriate for your site. 

Select the vertical datum used in your photo geotags

The industry standard for high-precision geotags uses WGS84 or the equivalent widely used datum for that region. For example, NAD83(2011) in the USA, GDA94/2020 in Australia is the horizontal datum, and ellipsoid height is the vertical datum. We assume that the horizontal datum will be in this datum, but we allow for the vertical datum to be specified.

Please select the vertical datum that your photos were corrected to by your RTK software. Failure to do so can lead to delays when processing your data and may require you to resubmit the dataset.

Complete the rest of the upload

Finish your upload by following the standard steps in a survey data set:

  • Configure the outputs, including selecting a filter.
  • Verify in the Dataset details that the images have high-accuracy geotags.

  • Submit your data for processing.
