    OpenAthena™ for iOS v2.5 release: Instant geolocation from any drone image

    Not sure, what exact error message does it give? If it says something like 'missing EXIF data' then it's probably something with how the photos were copied rather than how they were taken from the drone

    OpenAthena™ for iOS v2.5 release: Instant geolocation from any drone image

    Also the Mavic 2 Zoom has some of the best accuracy of any of the models we've tested so far. I'm also eager to do testing with the Mavic 3 given its nice telephoto zoom camera

    OpenAthena™ for iOS v2.5 release: Instant geolocation from any drone image

    EXIF metadata is basically just hidden tags and values automatically included in images taken by a camera. It doesn't need Internet access to record these tags when an image is taken. Usually it includes stuff like exposure time, camera settings, focal length, etc. For drones, it often includes...

    Is there a definitive source for DJI drone camera specifications?

    Notation for sensor size is a whole big can of worms. Basically, the published numbers are usually just a marketing gimmick based on decades old notation called 'optical format' owing back to when camera sensors were based on vacuum tubes: https://en.m.wikipedia.org/wiki/Optical_format...

    We'll take another look at DNG photos I believe last time we evaluated them they had the same EXIF metadata but didn't have the XMP metadata for stuff like camera angle, but it's certainly worth another look. That's great feedback on possible usability improvements.A Mac version with easier...

    Is there a definitive source for DJI drone camera specifications?

    Hi @DJ Wes, We maintain a list of most DJI camera parameters (including sensor size) for our OpenAthena software. This data allows for angle calculation from any pixel for our software's terrain-raycast: The full list is below. We try to keep it updated as new models come out, but definitely...

    OpenAthena (optical terrain-raycast app for drone images) updated with support for Mini 4 Pro

    Not at all! Good questions, as they are foundational to the functioning of the software. The app introduces a new technique for sensor fusion of drone images (and their included metadata) with a Digital Elevation Model of terrain. A significant benefit to this approach is it can work instantly...

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

    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:
