The Application of Graph in BIM/GIS Integration

The Application of Graph in BIM/GIS Integration

Blog Article

Information exchange between building information modelling (BIM) and geographic information system (GIS) is problematic, especially in terms of semantic information.Graph-based technologies, such as the resource description framework (RDF) and the labelled property graph NUTRI SEA OMEGA 3 (LPG), are promising in solving this problem.These two technologies are different but have not been systematically investigated in the context of BIM/GIS integration.

This paper presents our systematic investigation into these two technologies, trying to propose the proper one for BIM/GIS data integration.The main findings are as follows.(1) Both LPG-based databases and RDF-based databases can be generally considered graph databases, but an LPG-based database is considered a Wall Art (Set of 2) native graph database, while an RDF-based database is not.

(2) RDF suits applications focusing more on linking data and sharing data, and (3) LPG-based graph database suits applications focusing more on data query and analysis.An LPG-based graph database is thus proposed for BIM/GIS data integration.This review can facilitate the use of graph technology in BIM/GIS integration.
