Abstract
In recent years research interests in 3D geospatial information have
been increased to provide location based services and to develop various 3D
urban models used in many fields such as urban planning, and disaster manage-
ment. Especially, due to increasing the scale and complexity of buildings, many
researchers have studied to provide the services such as indoor navigation for dis-
aster. In order to manage complicated indoor spatial information efficiently, it is
necessary to develop the indoor spatial data model by extending the developed 3D
spatial models which have been developed for outdoor space. Although CityGML
(City Geography Markup Language) is an international standard model and it sup-
ports five Level of Detail for spatial data of urban areas, it is limited to represent
and manage indoor facilties in indoor space. In this chapter, we have proposed
CityGML Indoor ADE (Application Domain Extensions) applied to implement
indoor space and indoor facility management applications. CityGML Indoor ADE
is composed of two feature models including indoor space feature model repre-
senting space features and indoor facility feature model representing indoor facili-
ties in indoor space. We generate the XML schema of the CityGML Indoor ADE
presented by UML diagrams and develop a viewer to visualize the XML docu-
ments in order to validate the indoor space feature model. As well, we construct
the sample data based on indoor facility feature model to demonstrate the useful-
ness of the model for indoor facility management applications.
