Proper knowledge management system is required to be collected the knowledge and information according to the business task and, as the results, it should be used to create, manage, and make the right knowledge available to the right member people at the right time. So, a proper selection and gathering of the information enables us to create new knowledge. For the purpose of the proper and effective information retrieval, it is also needed to realize the navigational interface, which enables visual information retrieval using the image or drawing expression in addition to the related keyword assignment. Furthermore, visual interface use is expected to support that the user who has not some concrete retrieval key words, gets the objective information with ambiguous reference knowledge. This paper presents the information organizing and retrieval interface using geographical map, which enables us to share the knowledge among engineers in the cooperative work.
