MAP PRODUCTION AND USAGE IN SINGAPORE

Abstract

Maps are important tools of communication used to help understand spatial phenomena by geographers, navigators, planners, historians, tourists and many others. The present study is undertaken to examine the production process of the two mapping agencies, the Singapore Mapping Unit and the Hydrographic Department of the Port of Singapore Authority which respectively produce topographic/road maps and sea-charts. A further objective is to investigate the extent at which the maps are utilised by governmental bodies, private organisations and individuals. One of the significant findings of the study shows that the production processes of the two mapping agencies are quite similar except that the method of data collection differs. The Singapore Mapping Unit uses the technique of aerial photography while the Hydrographic Department uses depth sounding. This is so as the Singapore Mapping Unit is mainly interested in topographical features whereas the Hydrographic Department is concerned with maritime information for navigational purposes. Another significant finding concerns the various factors that influence the map design with the map initiator exerting the strongest influence. In the area of map usage, used mainly for navigation, it is found that the maps are orientation, planning and strategic studies. Because of the increasing demand for these maps, there is an urgent need to improve cartographic services of the two mapping agencies. Although there are various possibilities for improvement, computer-assisted techniques appear to be the most appropriate and effective method of generating higher quality maps to serve as efficient tools of cartographic communication.
