The script takes data points with latitude and longitude coordinates (list of points or a GPX track log) and plots them on a map so areas where points are dense show brightly.

Nice extras include: GPX tracks can be rendered as line segments instead of disconnected points. You can generate animations using ffmpeg. The heatmaps can be put on top of OpenStreetMap tiles.

The script is released under AGPL making it free to improve and share.

VisualEyes is an online tool developed at the University of Virginia. It allows you to combine images, maps, charts, video and data into interactive dynamic visualizations.

The examples offer multiple map layers, charts and of course a time slider to navigate through time.

VisualEyes example: Jefferson's Travels to England

The aim of Time Manager plugin for QGIS is to provide comfortable browsing through temporal geodata. A dock widget provides a time slider and a configuration dialog for your layers to manage.

Time Manager filters your vector datasets and displays only features with timestamps in the user specified time frame.
