Animation to Display Time Series
Animated maps can help detect simple pattern changes of values through time.
Combining multiple parameters display with animation allows users to simultane-
ously compare and analyze spatiotemporal data in both temporal dimension and
space dimension. Users will then obtain the generic knowledge how different spatial
patterns of multiple variables change over the same time period. For example, from
1960s to 1990s, land surface temperature increases and the largest change appear
around polar areas.

Subset and Visualize Dataset
While displaying the entire geographic region of a dataset is useful for general
overview of the dataset, it is usually more useful to subset the dataset based on
an Area of Interested (AOI) selected by a user and then visualize and analyze
