Information System for Topographic Images Based on Subjective Information Processing Principle

一组地图图像是一个信息宝库，因为它包含了来自多个视点的各种信息。将地图图像视为视觉媒介，我们可以认为它是最复杂的二维图像之一。一般来说，从大量的地图图像中，根据我们的目的和意图，选择和获取一些我们真正需要的信息本身是非常困难的。因此，实现一个具有智能支持设施的个人系统是一个非常有趣的任务。在本研究中，我们试图构建一种能够根据用户需求获取、转换和产生相应信息的新型GIS（地理信息系统），并制定了一个名为主观信息处理原理的新框架。主观信息处理是指从一般信息源中，通过重复交互产生反映用户主观偏好的个体结果的过程。本研究的主要成果是开发了一种生成草图的程序，该草图可以根据用户的喜好进行变形。由于草图可以让他很容易地理解两个指定地点之间的路线，这将是一种有效的辅助工具。该过程的特点是通过引入参数来控制任何简化级别的生成。除了草图，它的自然语言指令，解释路线，同时进行。草图及其说明被视为互补媒体的整合；视觉媒体和语言媒体。我们把我们的研究成果联系在一起，制作了一个原型系统。具有多媒体界面和信息检索、路网生成、路线规划、草图生成等功能模块。

A set of map images is a treasury of information because it contains a variety of information from a number of viewpoints. Viewing the map image as visual media, we may consider it one of the most complicated 2-dimensional images. In general, it is very difficult to select and acquire some information itself that we really need according to our purpose and intention, from a large set of map images. Therefore, it is of great interest to realize a personal system with intelligent support facilities for such a task.In this research, we have been attempting to construct a novel type of GIS (geographical information system) that is capable of acquiring, transforming, and producing the appropriate information according to a user's requirements as well as to formulate a new framework named subjective information processing principle. The subjective information processing indicates the process Of generating individual results reflecting on the subjective preference of users from a general information source by repeating interactions.The main result of this research is to develop a procedure of generating a sketch map drawing that is deformed as a user likes. Since the sketch will enable him to readily understand the route between the two indicated locations, it would be a kind of effective support tool. The procedure is characterized by controlling the generation at any simplification level by means of an introduced parameter. In addition to the sketch, its instructions by natural language, explaning the route, are made simultaneously. The sketch and its instructions are considered as the integration of complementary media ; visual media and linguistic media.We have made a prototype system by linking the results of our research. It possesses the multimedia interface and the functional modules : information retrieval, road network generation route planning, and sketch map generation.
