QGIS Time Data Control (QTDC): A plugin for animating time-tagged data
QTDC adds an interactive data animation capability to QGIS for vector layers having a time attribute.
The user can interactively control animation and specify the animation time context,
specifically: when in time, how much time, and how fast to animate the time-tagged data.
Multiple layers can be animated with QTDC simultaneously.
The UI also provides a histogram representation of data volume over time for each loaded layer.
The histogram doubles as a control for adjusting where in time and how much time to display.
Animation is bi-directional and is controlled either with UI buttons or with mouse gestures on the histogram.
There is also a basic API that exposes a subset of QTDC operations for interaction with other plugins.
