5. VISUALISATION 
Computer visualisation makes comprehension of analyses more 
efficient. Very realistic and detailed visualization becomes 
possible by “planting” real images of trees on a digital elevation 
model (Yoshida & Kimura, 2001). Such an approach was taken 
in this study. The ancient vegetation layer produced in the 
section 3 determined types of trees to be “planted” on the DEM 
of the study area. The introduction of real tree images to the 
visualisation enabled production of realistic close-up 
perspective images. Deployment of processed data sets in this 
manner is highly efficient for comprehension of past 
environments. Furthermore changes of vegetation distribution 
can be summarised as a movie clip.

The overhead views are suitable for two-dimensional 
observations of changes of vegetation distribution. For 
observations of changes along altitude, perspective views were 
also produced.
