These codes download and preprocess GNSS position timeseries data to generate 4-month displacement fields.

The displacement fields are saved in data/processing/*.fnl

HOW TO USE this repository

• Install ipython
• alias python=python3
• Clone the entire repository: git clone https://github.com/jey-kim/GNSS2FNL.git
• Go to the cloned directory and run process_GNSS2FNL.sh sh process_GNSS2FNL.sh

Running process_GNSS2FNL.sh will download GNSS data, preprocess GNSS position time series measurements, and generate *.fnl files.
Each of the *.fnl files is a 4-month displacement field for a month.
To know the month and year of a displacement field (a *.fnl file), check the output file displacement_time_label.dat

The element in the ith row of displacement_time_label.dat file is the month and year for a i.fnl file.
