Three-dimensional (3D) mapping once using a simple tools and conventional tools. Along with the development of the technology, the tools that were once used is replaced by a Laser Scanning technology. Terrestrial Laser Scanner (TLS) is one of the tools of technology laser scanners that are strongly supported in the object model returned a form have been created also called reversed engineering. With these tools, detailed 3D model of an object can be obtained easily. A metodology to do the 3D mapping with TLS is early planning, data acquisition, registration data, filtering data, for obtaining the 3D form that will be modeled in the software. Model from the 3D mapping steps with TLS is very influential with the conditions and the situation on the field. Percentage of noise (noise) acquired after the filtering was 12.32% of the point clouds raw data which is obtained after the scanning processes. The result obtained on the TLS data processing in this research is the 3D model of the Pasupati bridge which is already in Triangulated Irregular Network (TIN). From point clouds filtering process that was done before, was done bridge pillar height data validation with height data obtained from data retrieval on the pillar Pasupati bridge using ETS. The difference between the values obtained from the processing of data by the software Cyclone 7.1 and ETS data has a range of 1 mm - 2 dm. The results of this research are expected to be used as a follow-up study in advanced research later to see the study of deformation of Pasupati bridge. However on the modeling still have error because the shape object has a data void due to filtering process because there is a lot of noise in the data scanned TLS. The benefits of this research is to look at the performance and problems of the Pasupati bridge 3D mapping by using TLS.
