Hi Christophe

I must make a correction . I have not tried ExifSRational and int32_t simultaneously.

I will certainly try this combination along with your changes when possible.

Hi Christophe,

I have tried int versus uinit and SRational for lat. with no change.

Nonetheless, I appreciate your effort, but I think Felix maybe right about exif not being able to resolve negative values.

I am prepared to try any changes, but it is difficult at this time of year with wind - http://www.metservice.com/marine-surf/recreational-marine/wellington

I will update my repo and test as soon as possible.

Regards

Stephen

Hi Christophe,

Thank you for the prompt and possibly definitive reply. I will trial the change a soon as the weather permits.

In respect of the EXIF module and the IMAV 2015 flight plan procedure, the pleasure has been all mine. Enac’s IMAV 2014 flight plan and now TU Delft’s offer great insight into the extensive possibilities of Paparazzi NAV mode flight. I thank all concerned, even Parrot for the platform.

Hi Stephen,

Thank you for using the module. Sorry about the issue of neglecting the southern hemisphere.

I'm pretty sure the problem is the uint32_t type of attitude which obviously should get a sign: https://github.com/paparazzi/paparazzi/blob/master/sw/airborne/modules/computer_vision/lib/exif/exif_module.c#L30

Hi Christophe De Wagter

I posted the following question on paparazzi/discuss – Gitter (20/10/15) and failed to get a reply.

“Any ideas why the video_exif.xml module maybe outputting unintelligible GPS latitude reports in a southern hemisphere roaring forties location? View jpeg properties example”

Could you please offer some hint how to rectify this error.

Regards

Stephen Hulme
