“…Meijers et al (2005) implemented a three-dimensional GIS-based indoor model, to be able to perform the calculation of the most accessible evacuation routes in case of a calamity. Xu et al (2013) proposed a spatiotemporal-oriented three-dimensional model to represent the indoor space, which could be used to simulate indoor fire disasters in different scenarios. However, not all the presented models by the different grouped studies were made for emergency response.…”

The increasing dissemination of geographic information systems (GIS) in recent years has broadened the availability and use of geospatial tools, mostly to analyze the spatial data of different territories. A territory can be viewed at different analysis scales, and some buildings are as complex as small cities, presenting the opportunity to use GIS to study the dynamics, patterns, and phenomena within a building. This study presents a systematic literature review of the relevant evidence focused on the utilization of GIS in indoor spaces. To this end, we searched in three scientific libraries following the PRISMA statement guidelines. All phases were analyzed independently by two of the authors and agreement between them calculated through the Kappa statistic. In total, 50 studies were included. A qualitative synthesis was performed, considering the assessment of data and heterogeneity of methodologies within the included articles. Subsequently, the studies were categorized into five groups: indoor management, indoor geospatial analysis, indoor positioning, indoor data acquisition, and indoor spatial data models. The results demonstrate that research on the use of GIS in indoor spaces is still emerging, despite its great potential to help and GIS users, data producers, researchers, or policymakers to improve their work, providing scientific evidence for decision support.

“…Thus, geographic information and its services become real-time, dynamic, and online [2]. Some researchers have claimed that GIS has evolved from static GIS to temporal GIS and then to real-time GIS from the perspective of time [3,4]. Real-time GIS is a type of GIS that can acquire, manage, share, process, and service real-time or near real-time geographic objects/information as well as simulate and process dynamic geographic processes [5].…”

“…Many existing GIS applications focus on dealing with or analyzing real-time data for an application, such as ice forecasting [7], accident prevention on toll motorways [8], traffic systems [9], high-sulfur gas emergency responses [10], mapping of weather data [11], digital mapping for local governments [12], processing of marine environment data [13], and hydrography applications [14]. Then, real-time models and technologies were adopted to realize certain real-time functions or aspects of a GIS [3,15,16].

The timely sharing and interoperation of multi-source cross-sectoral information is an important issue for a Geographic Information System (GIS). To study this issue, a real-time and open GIS model called GeoSensor is proposed in this work. GeoSensor integrates the real-time GIS model, real-time computation framework, and Open Geospatial Consortium services. This paper illustrates the system architecture and the implementation methods of the GeoSensor. One of the methods developed is the conceptual mapping of a real-time GIS data model to open GIS models and services and a real-time computation framework. The other method developed is the integration of open GIS services, a real-time computation framework, and hybrid databases. The GeoSensor was tested in a case study of building a smart river. In the case study, a comprehensive sensor web was constructed and integrated with the real-time information on rainfall, beacon, channel, sediment, and water levels derived from space-based sensors, air-borne sensors, and underground sensors from multiple sectors in the Yangtze River basin. The GeoSensor manages the comprehensive sensor web with 32 types of sensors and more than 10 billion observation records. Three application systems were developed based on the GeoSensor to manage flood control, hydropower production, and navigation of the Yangtze River. The results of the three application systems show that the real-time and open system improves the management efficiency of the Yangtze River. This system is promising for managing smart rivers.

“…The data should encapsulate the relevant heterogeneous data, including the video stream, spatial references, interpretations of the video data, and geographical scenes. The additional data can enrich retrieved GeoVideo data and allow users to focus on analysis of the valuable information captured by video monitoring [6,29].…”

Abstract:With the wide deployment of the video sensor network and the rapid development of video spatialization technology, the large volume of complex GeoVideo data necessitates improvements in the application efficiency of the GeoVideo database and GeoVideo surveillance system. Traditional storage management approaches focus on the optimization of access to the GeoVideo stream. However, they suffer from poor management of the diverse movement processes contained within it; for example, they cannot support associative queries or comprehensive analysis of multi-type GeoVideo data in complex geographic environments. This paper takes physical movement process in GeoVideo as a new type of object and carries out an objectified organization of the heterogeneous GeoVideo data around it (including the video stream, spatial references, interpretations of the video data, and the overall scene) in a Not only SQL-Structured Query Language (NoSQL-SQL) hybrid GeoVideo database. This paper systematically explores the hybrid spatiotemporal indexes and multi-modal retrieval methods around movement processes, which enrich the query modes of the GeoVideo data. A prototype implementation and experimental analysis are presented to prove the feasibility and effectiveness of this organization and retrieval approach.
