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.

Required Inputs 

  • 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.


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

For more information on these validations, please see our pilot help materials

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 to the right.

The dataset name is how this dataset will be referred to in the Viewer and is defaulted to the dataset date.

Ground Control Points / Checkpoints

There are four options for adding ground control and/or checkpoints when submitting a survey:

  1. Adding an AeroPoint flight,
  2. Uploading a CSV file with ground control points, 
  3. Adding both an AeroPoint flight and CSV, or
  4. Not adding ground control.

Elevation model filtering

Elevation model filters are used to remove undesired artifacts such as trees, buildings, equipment and vehicles from the digital elevation model output. 

As part of output configuration you can select either
a) unfiltered, or
b) from four available filter settings, as below. 


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.


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.
