I can not create an orthophoto


I shot a mapping image using DJI MAVIC 2 ZOOM and created an orthophoto using webODM, but the following error occurred. Please tell me how to resolve.

An orthophoto could not be generated. To generate one, make sure GPS information is embedded in the EXIF tags of your images, or use a Ground Control Points (GCP) file.



Hey @rokusuke, would you be able to share the images you are using?

Also, what happens if when creating a new task you choose “Resize: Yes (In Browser)” from WebODM?



Thank you for your reply.

I prepared a photo on the link below.

For webODM, “Resize: Yes (In Browser)” is selected.
The size is “2048”.
The same error occurs for the result.



Can confirm this is a bug. I’ve opened an issue to track it at https://github.com/OpenDroneMap/ODM/issues/946



The following e-mail came from DJI.

We become indebted to.
It is DJI JAPAN Technical Support.

I sincerely apologize for taking time to answer.

We confirmed to head office department We are currently experiencing abnormality in altitude calculation recorded in EXIF ​​information due to product firmware bug.

※ This problem occurs only in calculation of the value entered in the EXIF ​​information, altitude on the application or altitude recognized by the barometer of the aircraft is normal.

According to the specifications of our products including Mavic 2, errors are always generated at the altitude in the Exif information, but it is planned to be alleviated by future Mavic 2 firmware update.
At present, the release date etc. are undecided.

I apologize for any inconvenience,
We appreciate your understanding.
