Application of geographical information system for the 3d modelling of close-range photogrammetry for documentation and landscape development of historical monuments

Abstract

Historical monuments, in the form of immovable objects such as temple buildings are part of our lives, they represent our history. Historic buildings must be preserved for future generations, by documenting buildings in 3D. Three-dimensional (3D) Geographic Information System (GIS) can be used for landscape development planning around the building. 3D-GIS with GIS analysis function to provide information related to geographical location and 3D visualization. 3D GIS models can be interpreted as digital representations of terrain and objects contained in around. In this study, the method used is a close range photogrammetry method for 3D modeling using a non-metric digital camera. For the stages of research implementation, the stages of camera calibration, object shooting, processing of 3D models are divided. For the calibration process, 80% is obtained, fulfilling the calibration requirements. The building modeling phase consists of Automated Projects, the process of calculating and creating 3D models, 3D coordinate transformations, 3D model visualization and statistical analysis. Documentation of Gedong Songo Temple in Semarang Regency. This study 3D model results testing is done by calculating the difference in the distance of the model with measurements in the field (terrestrial) with the Electronic Total Station (ETS) and the distance measuring Tape. The results of the distance comparison analysis obtained a maximum distance shift value of 4.00 centimeters and an RMS value of 4.69 centimeters. The values obtained are relatively small.
