Final comments
Animation is an important technique in our use and
understanding of spatial data. Cartographic animation
demonstrates that individual maps are only a snap-shot in time.
One should ask: What was before? What will come after? What
trends would be evident if the time element could be viewed as
an animation? The individual map is a snap-shot not only in time
but also in terms of the data. What non-temporal trends would be
evident if a map were viewed along with other related data sets
(e.g., age distribution in a city)? Finally, the individual map is a
snap-shot in the choice of the representational forms that were
used to depict the world. The use of different symbols or data
classifications can also constitute an animation.
Interactive and Animated Cartography (1995)
The Problem
Cartographic animation is not widely used. Why?
Top Five Problems
1. File size
Distribution dependent on the Internet
Internet users are impatient.
Animation files take too long to download.
Compressed video formats (youtube) are
unacceptable for maps.
Top Five Problems
2. Animations are hard to make
Essentially consist of many maps, requiring multiple
data sets
May require different levels of generalization
GIS programs either don’t incorporate animation or
have poor implementations
Top Five Problems
3. No monetary incentive
Why make many maps when most people are satisfied
with one
Top Five Problems
4. File format
No standard file format for cartographic animation
Will the file be readable by different computers?
Will the file be readable in the future?
Top Five Problems
5. Animation is by definition a non-interactive experience
With an interactive map, you can always change
something
With paper map, you can always look around the map
With animation, you look at a very small area of the
screen
With animation, you just sit and watch - and this is
boring
The Future of Animation
1. 3-D movie technology will transfer to computers
3-D map animations
2. Faster Internet capable of transmitting larger files
3. Better software to make animations
4. More interactive playback/creation
5. People may eventually expect that maps be animated
