How to Extend IndoorGML for Points of InterestWork-in-Progress Paper

摘要

Nowadays, the interest in spatial information services is growing and moving towards indoor spaces. Indoor spatial data is fundamental as the demand for expressing complex urban environments, in the context of providing location-based services. OGC IndoorGML was established as a geospatial data standard, especially for indoor navigation. OGC IndoorGML provides a broad definition of the expression and structure of indoor spaces, but point of interest (POI) is excluded from their scope. However, POIs are useful for indoor navigation not only outdoor navigation. In this paper, we propose a data model that describes POIs in an indoor environment considering various spatial and temporal aspects, as an extension model of the OGC IndoorGML, called indoor POI (InPOI) model. The InPOI model defines new entities to handle Spatio-temporal POI information in indoor space by specifying the OGC IndoorGML core module. Finally, we provide an XML schema of the InPOI model.
