Abstract. The goal of the following article is to outline the method of a gathering of geodata for a historical building and prepare outputs for the Historical Building Information Management. The study site where the geospatial data was captured in the caravanserai in Koysenjaq in Iraqi Kurdistan. Caravanserais are simply accommodation buildings for merchants which were positioned all over the Silk Roads and are spread from China to Turkey. According to UNESCO the historic importance of such buildings lays in the cultural and religious traces left from the merchants who used these sites to even socialize. The caravanserai in Koysenjaq is unfortunately ruined and gathering geospatial data about the state of the construction was captured using close-range photogrammetry and Simultaneous Localization and Mapping technology. The goal of the research was to not only capture data but also reconstruct an orthophoto map of the current state, compare it to the vector state of the floors and prepare data for BIM.
