Abstract

Technological developments in the field of surveying and mapping remain in progress. One technology that provides precise and accurate results is the terrestrial laser scanner (TLS). This technology can generate millions of points in a short time and represent objects in 3D. TLS technology has become famous for heritage documentation purposes due to its ability to obtain detailed geometry and information from maintaining historic buildings. This research is in the Dutch Cave, Djuanda Forest Park, Bandung, West Java, to map and document 3D. To produce accurate data, frame measurements were carried out using a total station, GNSS, which ended with acquisition using TLS. The registration method used is the target-to-target method. The goal of this research is to create as-built drawings of the Dutch Cave in analyzing the Dutch Cave's form in greater detail. This investigation determined that the Dutch Cave measures 124.435 meters in length and has a height difference of 69.7 cm between the entrance and the exit. The as-built drawing of the Dutch Cave illustrates that the shape of the cave varies from entrance to exit. There is a cave chamber that widens by 18.8 cm toward the cave's center and narrows by 20.7--32 cm toward the cave's exit. The Dutch Cave has a slope of between 1 and 5 degrees. The Dutch Cave 3D data can be used for a documentation archive for the Djuanda Forest Park.
