QUANTIFYING GEOMETRIC CHANGES IN BIM-GIS CONVERSION

Abstract. A conversion process is often carried out to migrate data during BIM and GIS integration, from the highly detailed less environment. Due differences between two systems, information loss occurs conversion. While research has been focusing on addressing semantics, it also necessary quantify geometric changes resulted converting geometry representations used in systems. This paper describes a preliminary study which evaluates for list of primitives. The outcome shows that metrics are useful both those carrying balance potential resulting complexity, end users converted assess fitness purpose impact results.
