SECONDARY DATA COLLECTION AND HERITAGE DOCUMENTATION - CASE STUDY OF A REMOTE DOCUMENTATION OF TRAVNIK’S VAROŠKA MOSQUE

Abstract. After two disastrous fires in Travnik in 1903, the Austro-Hungarian administration designed a new and secure mosque building model typology following a distinctive style of Habsburg-Bosnia. In order to understand the interventions which were carried out in that time, the research team examined the limited plan documentation from the 1990s. and collected the basic measurements by working on-site. Because of extended requirements, and new target areas being developed later in the project, more data for further research was needed. This paper will examine the possibilities of supplementing the existing materials collected on site by including new secondary sources into the processing. It will discuss the extent of combining data from different sources collected by means of crowdsourcing to conduct photogrammetric models and improve the quality of its result. Also, it will show how this material can refine already existing data and contribute to the precise documentation of the built heritage of Travnik, in particular to the 3D plan set of Varoška Mosque.
