This method can be used to reference different types of related information at the same time. An example is a guide that combines topological maps with architectural drawings and equipment lists. Another possible application is the display of electronic news and Internet information. One known system spatially arranges news articles ( Rennison 1994) while another displays compound information on a map ( Lokuge 1995).
Examples of cable ducting (underground facility) combined with above-ground equipment management are shown in Figure 4. Specific information is emphatically displayed by pushing the button. In addition, layer order and visual attributes of layers are automatically decided. This method is very effective in combination with GIS software. By this application, the overlapping information is made easy to compare and recognize more, and the information on height and depth can be expressed. A more detailed examination of benefit and convenience on the proposed method is advanced.
Figure 4. Examples of application
To make PDA easier to use, this paper proposed the information display method by which a large amount of information can be displayed in a small display area. Tests confirmed that, for text information, text size is important discrimination features. The example of application was illustrated.
