ABSTRACT: While the
use of three-dimensional (3D) geographical information system (GIS) is becoming
in rapid development and being used in various fields such as urban and
regional planning, disaster management and planning, mobile navigation and
etc., commercial and open source GIS software packages tend to offer 3D-GIS
functionalities for their products. On the basis, GIS analysis functions are to
provide information with respect to geographical location and by having 3D
spatial data as an input, it will give advantages in providing horizontal
position information. However, to analyze moving objects (temporal) in 3D seems
not an easy task and not fully supported by current GIS platform packages. Previously
in two-dimensional (2D) GIS practice, main issue addressed by researchers in
managing temporal spatial objects is GIS packages were designed based on
hardware and software constraints whereby it should be based on the temporal
spatial objects ontology. Nowadays, the trend of managing temporal 3D data is
via 3D spatial simulation or animation. This approach will not in assistance
for GIS users in conducting spatial queries. Without having a suitable ontology
and valid topological data structure for temporal 3D data, it will cause
repetitive of temporal data (redundancy) and complications in executing spatial
analysis in 3D environment. Therefore this paper focuses on the ontology for
managing moving 3D spatial objects (i.e.
air pollution, flood). The characteristics of moving objects were reviewed
thoroughly by categorizing it based on its different appearances. Moreover,
existing methods in managing temporal database were addressed and discussed for
its practicalities. Another important aspect in managing temporal 3D objects is
the implementation of topological data structures for 3D spatial objects were
reviewed. In the last section of this paper it summarized the issues and
further ideas towards implementing and managing temporal 3D spatial objects in
GIS based on the Geoinformation Ontology (GeO).
