ABSTRACT: 
The paper presents the recent development of the Photogrammetry Department of the Institute of Geodesy, 
Cartography and Photogrammetry in documentation of objects of cultural heritage. Work was focused on 
developing up-to-date metrical documentation of objects, promoting team work, promoting the use of 
photogrammetry in humane studies and preparing recommendations for technical standards. A review of the 
work is supplemented with examples of implemented projects. 
Key words: close range photogrammetry, architectural photogrammetry, computer graphics, three-

1. INTRODUCTION 
Institute of Geodesy, Cartography and 
Photogrammetry at the Faculty of Geodesy and 
Civil Engineering, Ljubljana was established 45 
years ago by the government and has today 
(accidentally) 45 employees. Although being a 
governmental institution, the Institute has to earn 
it’s income in the market, competing with other 
(mostely private) firms in Slovenia. In the 
Photogrammetry Department there are six people. 
Activities in the field are concentrated in: 
• close range photogrammetry (applications in 
architecture and archaeology) 
• topographical photogrammetry for national 
projects 
• production of 3D city models 
• education at the Faculty (practical works for 
students) 
2. ARCHITECTURAL PHOTOGRAMMETRY 
In the recent few years, the Photogrammetry 
Department of the Institute of Geodesy, 
Cartography and Photogrammetry has been 
intensely engaged in introducing contemporary 
forms of photogrammetric documentation for the 
needs of protecting the cultural heritage. During this 
period, the Institute has acted as contractor for the 
Cultural Heritage Office of the Republic of 
Slovenia and completet a large number of projects 
which are part of an umbrella project entiteled 
Surveys. In 1991, the then Institute of the Republic 
of Slovenia for the Protection of the Natural and 
Cultural Heritage placed a five-year projct entitled 
Surveys - Technical Photographs of More 
Demanding Structures which are part of the 
Cultural Heritage into the program of the Ministry 
of Culture. This was the first time that the Slovene 
monument protection service discussed the 
documenting of our cultural heritage more 
comprehensively as an important part of its 
activities (Grobovsek, 1996). Since the project was 
successful and became well-established, it is still 
being carried out. 
The basic goal of the project was to prepare 
photogrammetric documentation for monuments, 
but we also sought new and more appropirate 
product forms, more advanced technological
