Fit2UDDF

Here's a Python script to convert ANT/Garmin .FIT files coming from Garmin Descent MK1 into UDDF (Universal Dive Data Format). UDDF format (http://uddf.org/) is used by most Dive Log softwares while few of them are supporting .FIT file format

use Python 3

python Fit2UDDF.py -i <fit_file> -o <uddf_file>

• <fit_file>: Your Fit full file path
• <uddf_file>: The output UDDF file path

Dependencies

This script is using FitParse Python library to parse .FIT files but, it needs the modified version by xplwowi to take into account the Garmin Descent MK1 Specific fields. You can find it there: https://github.com/xplwowi/python-fitparse

Install

• Install python 3
• Download FitParse modified version from https://github.com/xplwowi/python-fitparse
• Install FitParse modified lib:

python setup.py install

Fresh install on Mac-OS

• Follow the tutorial here to install Python 3: https://docs.python-guide.org/starting/install3/osx/
• Create a workspace dir

mkdir python-workspace

• clone FitParse

git clone https://github.com/xplwowi/python-fitparse

• Install FitParse

cd python-fitparse
sudo python3 setup.py install

• Go back to your workspace dir

cd ..

• clone Fit2UDDF

git clone https://github.com/SPD13/Fit2UDDF.git

• run the script

cd Fit2UDDF
python3 Fit2UDDF.py -i <fit_file> -o <uddf_file>

Features

• Automatic Timezone conversion. Use the UTC Offset to convert dive time to local time
• Unit Conversion (C to Kelvin) for temperature

Supported fields

The following fields will be populated from the .FIT file

• gasdefinitions
• divesite Lat and Long
• greatestdepth
• divenumber
• density
• ndl_time
• lowesttemperature
• dive datetime
• diveduration
• samples: depth, temperature, time
