Abstract

Concern about environmental problems has grown rapidly over the last decades and
related to that emergent interest a lot of research has been done and regulations
applied. Today public scrutiny is more intense and participation in decision-making has
increased especially in forested environments. This situation requires good and easily
understandable information, but usually there is not enough communication between
authorities, managers and the general public. Those three components have to
interchange information about the landscape development and its natural resources in
order to maintain or improve environmental conditions. Therefore there is a need for
newer techniques of exposing and explaining the future consequences of different
management decision alternatives as well as showing forecasts according to different
scenarios.
It is well established that graphics, specifically data visualizations, are usually the
simplest and most powerful way for communicating results (Tukey, 1977; Tufte 1983).
This concept has been expanded to include the use of visualizations for representing
natural landscapes. Until recently, forest visualization efforts have focused mainly upon
illustrating static concepts or the possible outcomes of management actions (Bishop and
Karadaglis, 1997; McCaughey, 1997; Buckley, 1998). The development of computer
and visualization technologies is making more popular the use of computer
visualization as a delivery tool for the results of environmental change studies and
management plans, especially concerning forested environments (Tang and Bishop,
2002). Furthermore, there are large needs for visualization in illustrating scenarios and
forecast of forest growth, with different management alternatives, and give an idea
about the consequences of sylvicultural actions (i.e. cuttings, thinnings, etc.). When
delivering spatial and environmental information to a non-scientific audience, or even to
managers, it is important to put it in a convincing way, in order that the more important
data and their meaning are quickly understood. Particularly when referred to the
presentation of spatial data concerning to management or land use change, realism
provides the great advantage of familiarity to aid interpretation (Bishop, 1994). Owing to
this, the visualization is a powerful tool for communicating with the public on
participatory processes.
In this context, most commercial 3D visualization software packages have so far not been
able to satisfy the forestry related needs. Since currently, these software packages have
limitations, mainly because most packages have been aimed at Virtual Reality (VR)
capability. Those problems are related to the circumstance that in VR applications, the
computer tries to handle each tree as an object in the RAM memory, runn
ing into
memory problems quickly, and also less developed integration with georeferenced GIS
datasets, etc. For the basic forestry need, Virtual Reality capability is however not
necessary and the rendering of an image taken from one view point might be sufficient.
As an example of photorealistic visualization software, the new Visual Nature Studio 2
promises to be useful in different scales, with other interesting characteristics like vector
guided rendering, etc.
