Realistically representing our three-dimensional world has been the
subject of many (philosophical) discussions since ancient times.
While the recognition of the globular shape of the Earth goes back
to Pythagoras' statements of the sixth century B. C. , the
two-dimensional, circular depiction of the Earth's surface has
remained prevailing and also dominated the art of painting until
the late Middle Ages. Given the immature technological means,
objects on the Earth's surface were often represented in academic
and technical disciplines by two-dimensional cross-sections
oriented along combinations of three mutually perpendicular
directions. As soon as computer science evolved, scientists have
steadily been improving the three-dimensional representation of the
Earth and developed techniques to analyze the many natural
processes and phenomena taking part on its surface. Both computer
aided design (CAD) and geographical information systems (GIS) have
been developed in parallel during the last three decades. While the
former concentrates more on the detailed design of geometric models
of object shapes, the latter emphasizes the topological
relationships between geographical objects and analysis of spatial
patterns. Nonetheless, this distinction has become increasingly
blurred and both approaches have been integrated into commercial
software packages. In recent years, an active line of inquiry has
emerged along the junctures of CAD and GIS, viz. 3D geoinformation
science. Studies along this line have recently made significant
inroads in terms of 3D modeling and data acquisition.
