Hi Hwiyoung, when I try to run my own data file (jpg+txt) in the script I get the following error.
File c:\users...\main.py:57 in get_metadata
focal_length = convert_string_to_float(exif['Exif.Photo.FocalLength']) / 1000 # unit: m
KeyError: 'Exif.Photo.FocalLength'
Why do you think? How can I fix it?

Orthophoto_Maps/module/ExifData.py

Line 50 in 74e4ac9

focal_length = convert_string_to_float(exif['Exif.Photo.FocalLength']) / 1000 # unit: m

Hi

It seems that the data doesn't have metadata named "Exif.Photo.FocalLength"

I think you have to check a EXIF in the data using like exiftool
