This paper describes a suitable 3 dimensional measurement method and simplified data handling for relatively large scale of cultural heritage (Tyre, Lebanon) using the measurement instruments of the laser. Typically the raw data from the laser is outputted on relative coordinates, and it is difficult to determine where the behind object area cannot measure from single scanning station (referred as occlusion area). Therefore, methods of data acquisition and managing from various scanning stations and efficient method of determining the occlusion area are discussed. Scanning from various stations create large data files, and they make processing and analysis go slow in the field; thus efficient way to manage large measurement data set is also studied. At last, simplified way of visualizing target objects in 3 dimensions to depict its shape is studied as well.
