Introduction
Different type of maps and visualisations can be animated in QGIS. The following tutorials explain how to create animations.
Tutorial(s)
3D maps
3D maps are three dimensional data visualizations.
Create a 3D map and an animation from a DEM
Mariëlle Geers-Plasmans (Geojuffie): “3D kaartweergave en animatie“
Language(s): Dutch
Time: 10m 37s

Heatmaps
Heatmaps are 2D graphical representations of data in which values are depicted by colors.
Create a heatmap visualisation and animation
Ujaval Gandhi: “Animating Time Series Data (QGIS3)”/ “Geanimeerde gegevens tijdreeks (QGIS3)”
Language(s): English, Dutch
Chapters: overview of the task, get the data, procedure
EN: https://www.qgistutorials.com/en/docs/3/animating_time_series.html
NL: https://www.qgistutorials.com/nl/docs/3/animating_time_series.html
GRIB files
GRIB files (General regularly-distributed information in binary form) are a special binary format used to store gridded meteorological data, both historical and forecast. As it is highly compressed, it is suitable for internet up- and downloading.
Visualise storm Eunice
Hans van der Kwast: “Visualising Wind from a GRIB Mesh Layer in QGIS and Create an Animated GIF”
Language(s): English
Time: 12min 12s
Chapters: introduction (start-1:15), adding the data (1:15-1:55), styling GRIB mesh with arrows (1:55-3:24), adding a counter (3:24-6:17), adding scale bar and legend (6:17-8:40), exporting the frames (8:40-9:08), create animated GIF in GIMP (9:08-10:18), style GRIB mesh with traces (10:18-end)

Visualise precipitation data
Hans van der Kwast: “Visualise Precipitation Data from Mesh in Animations and Graphs”
Language(s): English
Time: 9min 6s
Chapters: introduction (start-1:15), styling the precipitation mesh (1:15-1:56), animating the precipitation mesh (1:56-2:31), more ramps and blending (2:31-3:18), calculate precipitation sum with mesh calculator (3:18-4:41), extract values at point (4:41-6:46), make graphs with the Data Plotly plugin (6:46-end)
Choropleths
Choropleths are statistical thematic maps that represent spatial variations of a quantity.
Join tables and create animations using the temporal controller
Hans van der Kwast: “Create Animated Choropleth with the QGIS Temporal Controller”
Language(s): English
Time: 19m 14s
Chapters: introduction (start-0:32), prepare the world map (0:32-1:32), prepare data tables (1:32-4:26), join data from different tables (one to one) (4:26-6:18), normalize the data (6:18-6:50), convert string to data attributes (6:50-7:53), join temporal data with polygons (7:53-8:53), styling the map (8:53-11:34), setting up the temporal controller (11:34-13:06), adding decorators and counter (13:06-17:36), export frames and create animated GIF (17:36-end)

Aerial images and objects
Aerial images are photographs taken from the air.
How to use the temporal controller to animate aerial images and objects

Raster models
Raster models is a method to store and present geographic information through a grid of cells.
