Abstract
Abstract. Indoor modeling and mapping has been an active area of research in last 20 years in order to tackle the problems related to positioning and tracking of people and objects indoors, and provides many opportunities for several domains ranging from emergency response to logistics in micro urban spaces. The outputs of recent research in the field have been presented in several scientific publications and events primarily related to spatial information science and technology. This paper summarizes the outputs of last 10 years of research on indoor modeling and mapping within a proper classification which covers 7 areas, i.e. Information Acquisition by Sensors, Model Definition, Model Integration, Indoor Positioning and LBS, Routing & Navigation Methods, Augmented and Virtual Reality Applications, and Ethical Issues. Finally, the paper outlines the current and future research directions and concluding remarks.
Highlights
Our complex world requires developing much smarter scenarios for our living environments
Along with the availability of spatial information almost ubiquitously in the current societies, spatial applications have been expanding into indoor spaces. 3D spatial information about indoor environments has increasingly been demanded in various applications such as risk and disaster management, human trajectory identification, and facility management
The scientific and technological progress in 3D spatial data acquisition as well as 3D city and building modeling has been evolving into more sophisticated hardware, software, standards, techniques and uses specific to indoor modeling and mapping
Summary
Our complex world requires developing much smarter scenarios for our living environments. Another area that the paper is focusing on is Integration, i.e. a topic which includes studies on fusion of information coming from multiple sources and the area covers efforts on integration of information residing in multiple data models Another area of research in the field is indoor positioning which refers to the task of inferring the location of a mobile device inside a building. For indoor location-based services (LBS), both sufficiently accurate positioning as well as quality and information-rich indoor maps are required (Werner, 2014) Proposing new and better approaches for indoor navigation and routing is an active field of research In this field some studies focus on optimization of routing where there are dynamically changing conditions and multi-targets. Ethical issues are important elements of research as these are concerned with privacy of people
