Kellie's Castle facade recording using digital close-range photogrammetry

Abstract

Various surveying techniques has been used in the mapping for engineering purposes. Mapping is an important element in Geomatic Engineering. Conventional technique for mapping includes surveying technique that consist of data acquisition work on site, plotting and calculating. This technique is tedious and time consuming. This study is aimed at studying and a comparing an alternative technique for mapping of the Kellies Castle building, namely digital close-range photogrammetry. The purpose of introducing close range photogrammetry technique in mapping is to increase efficiencies of estimation process as well the reliability of the results. Photogrammetry procedures were sets up to determine the map. Then, a simple verification test is done to verity the result using digital close-range photogrammetry. Comparison between digital close-range photogrammetry and conventional technique was made to prove that digital close-range photogrammetry capable to be used as one of the reliable techniques in non-topo mapping.
