OpenAthena™ for iOS v2.0 release: Geo-locate any point in your drone images

[Theta]

Hi!

We are Theta Informatics LLC, creators of the free and open source OpenAthena software platform for iOS and Android.

We're excited to announce the launch of OpenAthena™ for iOS v2.0.

This app introduces exciting new capabilities to your drone, greatly enhancing its mission capabilities. The app allows you to calculate the precise ground location of any pixel which appears in images taken by your drone. Our software's custom processing engine extracts metadata present in drone images and uses it with a digital elevation model to calculate the precise location on Earth of any selected point in your images. Possible applications of this technology include search and rescue, agriculture, disaster response and public safety, environmental monitoring, and land management.

The app allows you to
(for the first time ever):
1. Load any image taken by your drone
2. Automatically download an elevation map
3. Tap anywhere in the image
4. Instantly obtain its precise ground location!

The updated values for the Mini 3 Pro in our cameras database were generated by our manual camera calibration process, described in full here:

A new value for the Mavic 3 Pro's 1/1.3-in. Medium Telephoto Camera (EXIF model FC4382) was estimated using the best available information.

In addition to OpenAthena, we're also maintaining the cameras database as an open source project here:

Just verified the DJI Mini 3 is also incompatible, even though the Mini 3 Pro is.

Photos from the Mini 2 and Mini 3 are missing important metadata for the aim of the camera. This appears to be intentional on the part of DJI:
