Kaštel (Gradina) Trsat je jedan od najpoznatijih objekata graditeljske baštine u Primorskogoranskoj županiji. U svrhu projekta obnove, Grad Rijeka je 2015. godine naručio snimak kompleksa (ukupno skoro 8000 m²). Za izradu snimka korištena je laboratorijska oprema Sveučilišta u Rijeci. Cilj rada je prikazati proces snimka, dati analizu mogućnosti kombiniranja laserskog snimka s drugim suvremenim metodama (snimanje bespilotnom letjelicom, fotomodeliranje), usporediti rezultate snimka s postojećim snimkama kompleksa, utvrditi nove podatke o kompleksu te provesti diskusiju o rezultatima i važnosti koje ovakvo kompleksno snimanje može imati za očuvanje kulturne baštine.; Trsat castle is one of the most famous heritage elements in Primorsko-goranska County. In 2015, as part of the renewal design, the City of Rijeka has commissioned the survey of the complex (almost 8000m²). The survey was done using the laboratory equipment of University of Rijeka. The aim of the paper is to illustrate the survey process, to analyze the possibility of combining laser scanning with other contemporary methods (drone survey, photo-modelling...), as well as to compare the results of the survey with the previous surveys of the complex, and to determine new data about the complex and discuss the results, especially the importance of such a complex survey for cultural heritage preservation.
