Geodetic Velocities Visualization

Geodetic Velocities Visualization Screenshot

This visualization renders Global Navigation Satellite System (GNSS) position time series data on top of an interactive Google Map.

By manipulating the magnification level and the timespan, you can see how the Earth has moved over time.

Setup

To use Google Maps, you need a browser API key. Follow these instructions to Get a Key/Authentication.

Once you have your API key, open up the index.html file and find this line:

var apiKey = '';

Paste in your API key and save the file.

Usage

To use this visualization, first you'll need to produce or acquire a GNSS data file.

The visualization expects to find a file named beacon-data.json in the data/ directory. See the README file there for details on the format.

Once you have a data file, dowload this source code and serve the contents. If you have Python installed, you can use its SimpleHTTPServer to see this working locally.

$ python -m SimpleHTTPServer 8000

Then open a browser to http://localhost:8000 to see the visualization.
