| Abstract | The development of Geographic Information System (GIS) has put new vitality into maps
in widespread use for thousands of years as common reference and academic. 3D GIS as a
characteristic visualization of reality is more and more becoming an indispensable
component of the future's GIS, though automated generalization from 2D digital maps/GIS
is still the outstanding question. The future availability of automatic generalization tools
has allowed us to realize our goal, namely the generalization in 3D GIS, will be the basic
research in the field. This paper which is focused on the theoretical research for 3D
explores several different ways for generalization associated with simple examples: a)
Levels of systems which display different detail elements comparing to the area or scale
from large scale 3D GIS to small one; and, b) Generalization including surface
generalization, construction generalization and object generalization used to simplify an
entity's surface, construction and itself. These will provide an explorative approach to the
3D GIS production in normalization and comparability to each other. Some basic
algorithms and operators have been expanded from 2D GIS to 3D GIS. |
