项目摘要

It must be grasped what environmental resources exist in a river basin to preserve the fine nature and to create the comfortable living environment, However, it is difficult to think effectively about methods of environmental creation to preserve and utilize the environmental resources in such big rivers as the Yodo River runs through the metropolitan area because of urban problems. The environmental information system is asked to analyze and evaluate the relation between the urban activities and the environmental resources, and to support the planning and design. The investigators have been developing an environmental information system to grasp and analyze the regional landscape structure for the first step.The environmental information system deals with a wide area, based on a small-scale map drawn on a scale of 1 : 200,000 or a scale of 1 : 25,000. This system is combined with a commercially available geographic information system (GIS), CAD/CG system, database management (DBM) system, and databases to. visualize the regional information in the lower reaches of Yodo River, Japan. It is emphasized that a three-dimensional representation of the digital terrain model has been generated. The visualized data can be imported and exported among some application programs using a standard CAD data format. Thus, CG techniques such as texture mapping can be used easily. Consequently, the system expands the visualization of the regional information in cooperation with some platforms.

必须掌握流域内存在哪些环境资源才能保护优良的自然环境，创造舒适的生活环境，但由于城市问题，很难有效地思考环境创造的方法来保护和利用流经首都圈的淀川等大河流的环境资源。环境信息系统的任务是分析评价城市活动与环境资源的关系，为规划设计提供支持。研究人员正在开发一个环境信息系统，以掌握和分析区域景观结构，这是第一步。该环境信息系统涉及的区域范围很广，以1:200,000或1:25,000比例尺绘制的小比例尺地图为基础。该系统与商用地理信息系统（GIS）、CAD/CG系统、数据库管理（DBM）系统和数据库相结合。将日本淀川下游的区域信息可视化。需要强调的是，已经生成了数字地形模型的三维表示。可视化数据可以使用标准 CAD 数据格式在一些应用程序之间导入和导出。因此，可以轻松使用纹理映射等 CG 技术。因此，系统与一些平台合作，扩大了区域信息的可视化。
