This paper presents a comprehensive research study in mapping of structural building using Digital Close-Range Photogrammetric Approach. The building chosen for this research study is Ipoh Old General Post Office. Digital Close-Range Photogrammetric approach is capable in 3D mapping of building and able to deliver an accurate measurements, less in time then conventional approach (ie. total station / tape measurement). 3D point was extrapolated from 2D images acquired from various angles at the scene and fed into photogrammetric processor that capable in producing 3D model. This research study shows that user is able to navigate throughout the building with ease and accuracy. The images created in 3D model are irrefutable recording of the 3D points and lot of data can be interpreted and is presented as final outcome.
