Realtime data plot with map

Small web interface to show realtime data with a map.

It use the Python microframework Flask with :

• Bootstrap for the two-column design,
• Leaflet for the map,
• JQuery and the flot plugin for the chart.

This example is made from an idea of PythonWise blog.

For example, it can be use to follow a moving Raspberry Pi with a sensor data and a GPS. This Raspberry Pi must send data into a distant database.

I made fake_data.py to simulate a moving Raspberry Pi. monitor.py is a Flask application to show data on chart and map.

It works with Python 3.5.

How to use it ?

Clone this repository :

git clone https://github.com/jnth/realtime-data-with-map.git
cd realtime-data-with-map

In a terminal :

python fake_data.py /tmp/data.db

You will see random data like this :

sqlite3: create table ok
2015-12-13 11:36:16     3.961,   4.999422,  45.000980
2015-12-13 11:36:18    -6.000,   4.999101,  45.001092
2015-12-13 11:36:20   -13.732,   4.998480,  45.001525
...

Do not close the terminal and in an other terminal :

python3.5 monitor.py /tmp/data.db
