which goes along the roads. First, one animation spline which
goes over the campus area was created. Then a camera crated
and camera’s target linked to the spline. Time settings were
done with the time configuration commute. Movie time range
was determined 1:37 minutes for flying animation (Figure 6).
And frame rate was determined 24 fps for the smooth view.
Then camera angles were set for the animation. Creating the
movie was created with the “make preview”. This process took
approximately 20 hours. If you study with a computer which
has high capacity processor and rem this process can be
complete in lesser time. For the second animation there is a 3D
car drawing downloaded from internet (www.3dcafe.com). The
car was not necessary for the second animation. But it is better
for emphasizing the roads. The second animation's aim is
visualizing the surface of the area like walking on the surface.
There is a line was drown for the linking camera' target. At the
same time the car was brought the road. And a camera was
created near the car. The car and camera's target linked to
road's middle axis. Movie time range was determined 1:30
minutes (Figure 7). And movie created after 6 hours program
processing.

3. CONCLUSION
Nowadays there are various visualization techniques. So there
are lots of softwares which can be used for the visualization
process. Which is the most proper software. for the cartographic
visualization? This choice is important for the cartographers.
For this reason I did this case study. I studied with two different
software and I saw that both of them have some advantages and
disadvantages.
3D Studio VIZ software has good characteristics for 3D
visualization and animation. It has enough options for movie
making. You can create a movie all the perspectives and every
places of the project. You can create different movies in
different time segments. Its material box, render options and
surface covering options make it useful for 3D visualization
study of a campus. It includes three different surface covering
types. But it don't has cartographic presentation objects. For
such a project, a PC with high capacity is important with
respect to productivity.
Vertical Mapper has lots of cartographic options. For example it
has Grid Manager options for visualizing height information
and it has also different interpolation and modelling methods.
Its 3D modelling options has good properties. For instance it
has scaling along the z-axis on the Grid View options window.
And user can zoom and rotate the model. Then he or she can
render any of the perspective of the model. But there is no
movie making options. And only terrain can be visualized.
There are no options for creating buildings, trees and other
natural varieties. A PC with average capacity is enough for
study with this software.
In conclusion 3D visualization processes have to include some
cartographic methods. Cartograpy discipline should determine
cartographic rules for visualization softwares. The proper
softwares should be created after the determining the rules.
