3D geometry-based indoor network extraction for navigation applications using SFCGAL [Elektronski vir]Tekavec, Jernej, geodet, 1989- ; Lisec, Anka, geodezija, 1978-This study is focused on indoor navigation network extraction for navigation applications based on available 3D building data and using SFCGAL library, e.g. simple features computational geometry ... algorithms library. In this study, special attention is given to 3D cadastre and BIM (building information modelling) datasets, which have been used as data sources for 3D geometric indoor modelling. SFCGAL 3D functions are used for the extraction of an indoor network, which has been modelled in the form of indoor connectivity graphs based on 3D geometries of indoor features. The extraction is performed by the integration of extract transform load (ETL) software and the spatial database to support multiple data sources and provide access to SFCGAL functions. With this integrated approach, the current lack of straightforward software support for complex 3D spatial analyses is addressed. Based on the developed methodology, we perform and discuss the extraction of an indoor navigation network from 3D cadastral and BIM data. The efficiency and performance of the network analyses were evaluated using the processing and query execution times. The results show that the proposed methodology for geometry-based navigation network extraction of buildings is efficient and can be used with various types of 3D geometric indoor data.Source: ISPRS international journal of geo-information [Elektronski vir]. - ISSN 2220-9964 (Letn. 9, št. 7/417, 2020, str. 1-15)Type of material - e-article ; adult, seriousPublish date - 2020Language - englishCOBISS.SI-ID - 21687043
