Cultural heritage is an important factor in the life of every human being. It helps us to understand previous generations as well as the history of where we come from. In order to save cultural heritage for next generations, there is a need for their preservation. The main purpose of this paper is to show aspects concerning combining two technologies for acquisition and documenting of historical objects for preserving purposes. The recent development of computer and information technologies caused replacement of traditional acquisition methods with nowadays popular technologies. The paper also describes the principle of these technologies, terrestrial laser scanning (TLS), aerial laser scanning (ALS) and their main products. Advantages provided by these technologies are fast acquisition, very dense 3D point clouds with high accuracy and also a very short period of time for its processing. Riegl LMS – q680i and Leica ScanStation P20 3D laser scanner were used for surveying the area of Petrovaradin old town in Novi Sad, Serbia. Processing of raw data includes integration of two point clouds into one, noise filtering, meshing and drawings of the facade. The final step after processing of the data for Petrovaradin old town was a publication on the web in the form of panoramic images and point cloud viewer. In that way, anyone interested can view the data, perform measurements, draw cross sections or make a simple analysis. This project is a part of a (larger) project with the final model of complete area of Novi Sad.
