Abstract. We implemented the semantic models required to develop an indoor navigation system to assist the movement of users with different physical mobility conditions inside the building of the Faculty of Agricultural Sciences of the National University of Colombia. Everything starts with the recollection of architectural data followed by an analysis and depuration of unnecessary elements (geometrically and semantically) ending with two models: 1) a CityGML model of the interior of the building (LOD4), being the data source for the IndoorGML model and for visualization, 2) an IndoorGML model, provider of the semantic network for the future application of routing algorithms. We present resulting models with the discussion of the challenges and limitations that authors face during this work.
