What is the Processing Report?


A Processing Report is produced for every survey in Propeller. It includes information on the image quality, ground control accuracy, and ground control or check shot location on your site. The Processing Report also analyzes your site's survey photos and provides details about how well they align with the ground control points uploaded with the survey. 

Where is the Processing Report?

The Processing Report for your selected dataset can be found in the REPORTS category in the OUTPUTS tab.

A link to the Processing Report is also included in the notification email sent to you after a dataset has finished processing.

What is included in the Processing Report?

Survey information

This includes general information about your survey, including capture date, the uploader's name, the coordinate reference system, filter applied, processing corrections method, AeroPoint survey and its correction method (if applicable), the total number of source photos, Quality Assurance (QA) Information, including the QA level chosen when the dataset was uploaded, the allowable GCP error, and the allowable consistency with past surveys. You can also print out a PDF version of the Processing Report by clicking on the PRINT button at the top-right of the report.

Quality Overview

A message will be displayed here if there are any issues with your data.


In the Overview section, you will see the orthophoto of your survey with the ground control points (GCPs) and checkpoints marked over a base map. If you click on the icon for a GCP or checkpoint, a pop-up will appear on the map with information on that point, including the XYZ location. The same information appears below the map, except for the location. 

If your survey data contains a sufficient number of high-quality GCPs, an automated process will remove unnecessary ground control points from your dataset, helping to speed up processing times. If applicable, you'll also see which GCPs have been removed (both automatically and manually disabled).

Please note the auto-disabling of GCPs only applies to high-accuracy surveys.

Image quality 

Check the Photos box below the map to see the individual photos.

The Image Quality section shows a bar chart of image quality, with the image quality plotted against the number of images.

The tables below the graph provide more detail on the image alignment and error. 

Expected Ground Control Accuracy

This table shows the difference between the positions of the modeled and uploaded coordinates for the ground control points. The table includes the X, Y, and Z errors and total error for each ground control point. The total error is the distance in 3D space between the model location and the uploaded location for the ground control points.

The total error should be less than 0.1 ft or 3 cm.

Ground Control Summary

This summary provides the location of each ground control point and checkpoint used to create the model of your site. It also provides the difference in elevation between the final model and the submitted control point for the same Easting and Northing coordinates.

You can view any unused points by checking the box below the table.

How can I use the Processing Report?

The information in the Processing Report can be used in various ways, including better understanding your model’s accuracy, learning how to improve future surveys, and validating areas between GCPs using checkpoints. For a more detailed explanation, contact your customer success representative.
