Flight Review

This is a web application for flight log analysis. It allows users to upload ULog flight logs, and analyze them through the browser.

It uses the bokeh library for plotting and the Tornado Web Server.

Installation and Setup

• use python3
• pip3 install bokeh jinja2 sqlite3
• at least version 0.12.3 of bokeh is required. Install with: pip3 install bokeh
• configure web server settings in plot_app/config. This can be skipped for a local installation.
• ./setup_db.py to initialize the database

Usage

For local usage, the server can be started directly with a log file name, without having to upload it first:

./serve.py -f <file.ulg>

The plot_app directory contains a bokeh server application for plotting. It can be run stand-alone with bokeh serve --show plot_app (or with cd plot_app; bokeh serve --show main.py, to start without the html template).

The whole web application is run with the serve.py script. Run ./serve.py -h for further details.

Interactive Usage

The plotting can also be used interative using a Jupyter Notebook. It requires python knowledge, but provides full control over what and how to plot with immediate feedback.

• pip3 install jupyter
• Start the notebook: jupyter notebook
• open the testing_notebook.ipynb file

TODO list

• maximum upload size is currently limited to 100MB. This requires a bokeh setting.
• add SSL
• Not all bokeh widgets seem to be responsive to size changes
• better downsampling (use JS callback with queue & timeout (like InteractiveImage) and better algorithm)
• add location obfuscation option
• user management: login, per-user display templates
• download CSV option?
• ...
