Modeling Standards and File Formats for Indoor Mapping

摘要

Indoor maps provide abstractions of the physical spaces where we spend most of our lives. General purpose indoor maps have historically taken the form of two-dimensional floor plans, commonly found in public venues such as shopping malls and cruise ships. Until recently, innovation and development of indoor maps have remained confined to urban planning and the building industry. Recent interest in indoor mapping for other applications has extended indoor mapping to 3D and to other domains, with a growing emphasis on commerce and general wayfinding. This paper reviews prevailing modeling standards and file formats relevant to the modeling and visualization of indoor spaces with the goal of assisting researchers and developers with finding appropriate formats for indoor modeling and visualization.
