- Outline
- Ordinary maps show domains, and phenomena and events mapped onto them are
handled as features with position information, so they are generally a
two-dimensional (2-D) space. However, that approach is inadequate for geoinformatics.
Domains have height (depth) attributes, so at the very least a three-dimensional
(3-D) space is needed to express that information. For example, to create
a map of natural disasters such as flooding in Southeast Asia, it is essential
to be able to express data in three dimensions. Also, for research such
as studies into the history of the urban development, when historical phenomena
and events are examined utilizing maps, the time dimension needs to be
taken into account. Consequently, investigations require at least a 4-D
space.
The spatiotemporal mapping system is efficient and new approach to perceive
the 4-D transfiguration of urban city. This research will provide an outline
and method for analyzing of urban transfiguration using the spatiotemporal
mapping from underground and ground-based information.
