Abstract
Abstract. This paper presents a pipeline that aims at illustrating the procedure to realize a 3D model of a complex building integrating the UAV and terrestrial images and modifying the 3D model in order to publish to Google Earth in an interactive modality so as to provide better available models for visualization and use. The main steps of the procedure are the optimization of the UAV flight, the integration of the different UAV and ground floor images and the optimization of the model to be published to GE. The case study has been identified in a building, The Eremo di Santa Rosalia Convent in Sicily which hash more staggered elevations and located in the hills of the hinterland and of which, the online platform only indicate the position on Google Maps (GM) and Google Earth (GE) with a photo from above and a non-urban road whose GM path is not corresponding with the GE photo. The process highlights the integration of the models and showcases a workflow for the publication of the combined 3D model to the GE platform.

Where: Root Mean Square Error (RMSE) is the error, XFi, YFi, and HFi are the value measured in the field, XMi, YMi, HMi are the coordinates obtained from the 3D model, and n is the number of checkpoints
Summary
Nowadays the use of online Mapping systems is in high demand for tourism, cultural heritage and architecture purposes and research. There are numerous instances where it is not easy for the platform to have access to the sites given the location of some landmarks or sites and with regards to the complexity of the building or landmark (Remondino et al, 2009a). there are a vast number of models on the platform which do not provide a proper overview of significant points of interest and historical significance To this end, this paper looks at one such case and aims to develop a workflow for such a site where access is limited but a 3D replicated model of the structure is required for Cultural heritage. The case study has been identified in a building with staggered elevations and located in the hills of the hinterland and of which, the online platform only indicates the position on Google Maps (GM) and Google Earth (GE) with a photo from above and a non-urban road whose GM path is not corresponding
