I am trying to edit/modify existing metadata within python 2.7. More specifically I have GPS coordinates in a my metedata, however the altitude field is incorrect. Is there a way of changing this?
I have had a look at PIL piexif pyexif, but I cannot seem to find a way to modify existing fields.
Has anyone managed to do this? It sounds like it would be very simple, but I can't seem to work it out.

Select the picture you want to edit EXIF data for. To view EXIF data, you can tap the various icons below the image. To edit or remove EXIF data (after you pay for the app), tap Metadata. Now select Remove or Edit.
EXIF key-value pairs are called tags, and each tag can contain either a string or numeric value. There are dozens of tags in the current EXIF standard (version 2.32), and anyone — from smartphone and camera manufacturers to photographers — is free to add their own.
import piexif from PIL import Image img = Image.open(fname) exif_dict = piexif.load(img.info['exif']) altitude = exif_dict['GPS'][piexif.GPSIFD.GPSAltitude] print(altitude) (550, 1) % some values are saved in a fractional format. This means 550m, (51, 2) would be 25,5m.
exif_dict['GPS'][piexif.GPSIFD.GPSAltitude] = (140, 1) This sets the altitude to 140m
exif_bytes = piexif.dump(exif_dict) img.save('_%s' % fname, "jpeg", exif=exif_bytes) If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
