Integration of GIS and Digital Photogrammetry in Building Space Analysis

Abstract

A case study using digital photogrammetry approach in collecting information concerning the size of buildings has been carried out in the campus of the University of Malaya. A digital map that consists of spatial data of buildings and infrastructures in the campus is produced. The spatial data are arranged in layers using the base map with the scale of 1:3000. A GIS software called UM-INFO has been developed for the use in analyzing the information as well as for producing report on distribution of building spacious utilization map. Sufficient database such as numbers of floor for each block, areas of floor, numbers of student, numbers of staff etc were input to UM-INFO software. The use of building space for various purposes and other facilities in the campus are identified. Furthermore, the sizes of building space utilities are compared to the guideline by the National Economic Panning Unit of Malaysia. The study has discovered all the faculties and academic centers have at least 3% more than the nominal area except the Faculty of Art & Social Sciences (AFSSO). The AFSSO required another 50% more of the nominal area.

In conclusion, this study has proven the effectiveness of Digital Photogrammetry and Geographical Information System (GIS) in producing a map to show the distribution of space usage in higher learning institution. This research has successfully shown that the digital photogrammetry method is able to capture digital data much faster and accurately. The combination of digital photogrammetry and GIS technology has proven to be the best choice in optimizing the space usage. This technique increases productivity at low cost as well as serves as a very useful tool for planning purposes.
