Abstract
Abstract. With the recent increasing build and application for 3D spatial information, the importance of management and application for spatial information based on indoor space has been increased. Especially, Due to the increasing of the scale and complexity of the building according to the development of construction technologies several studies have been conducted to provide the services based on indoor space such as indoor navigation for disaster. Therefore, to efficient manage and service for information of complicated indoor space, it is necessary to extend and develop 3D spatial model and services that have been developed for outdoor space. In this paper, Indoor Spatial Data Model (ISDM) is developed to support building spatial information for complicated indoor space and location based services through topological information. ISDM contains a feature model which is a CityGML Application Domain Extension (ADE) model and a topology model that refers the IndoorGML.
Highlights
With the recent interests in 3D spatial information used for location based services, various 3D urban models used in many areas such as urban planning, disaster management have been developed
To manage and utilize efficiently for complex indoor space, data model which can be utilized and various services needs to develop by extending from 3D spatial information and service that have mainly developed outdoor space to indoor space
Existing spatial information and application services have mostly developed targeting outdoor space, and data models focusing on outdoor space have been defined and improved
Summary
With the recent interests in 3D spatial information used for location based services, various 3D urban models used in many areas such as urban planning, disaster management have been developed. The most important and basic thing is how to develop and implement 3D data model to provide 3D spatial information and location based services of indoor space. IFC (Industry Foundation Classes) has been adopted BIM data model by applying the object-oriented method and adopted XML as a method of expression [1] This standard data model was created to support interoperability among architecture, engineering and AEC and registered in the ISO/PAS16739 [4]. This study proposes Indoor Spatial Data Model (ISDM) representing the geometry and the topology of indoor space developed to support indoor location based services. The peer-review was conducted on the basis of the abstract
