项目摘要

In the lower reaches of the Yodo River where Osaka Institute of Technology is located on, the investigators tried to examine the historical changes of the natural environment and the social environment of Osaka metropolitan area by using the Integrated Spatial Information System based on GIS and CAD/CG system. And they tried to image the future Yodo River Basin, too. Concretely, they visualized changes of the cityscapes, bridgescapes, and the course of the Yodo River from Edo period up to the present with this system. Also, they clarified the effects and factors of the Yodo on industrial activities.The head investigator, Yoshikawa developed the system generating 3D urban models from the historical map corrected geometrically on the present map. Then he restored the typical cityscapes and bridgescapes of Osaka in Genroku era as 3D-CG models. Especially he preserved the bridegescapes around Nakanoshima for the inheritable excellent historical environment as the digital archives. The CG models of bridges, Tenma, Tenjin, Naniwa, Kohrai, Ohe, and Yodoya, were generated in every era, and visualized transitionally. He also selected Hirakata-stage where; the Edo taste is left in, and generated the present CG models as the first step. Now he is preparing to open these data to the public through the Internet.The investigator, Aya restored the river environment of the Yodo by using De Rijke's survey drawings issued in early years of Meiji era. He collected survey drawings and topographical maps issued after the modem survey techniques had been established, and clarified the river changes. Another investigator, Iwasaki clarified the historical changes of the water transportation system and the ports distribution assisting the industries on the Yodo. And he investigated the river reservations as the urban recreation space at present, and clarified the improvement tasks.

在大坂工业大学所在的淀川下游，调查人员试图利用基于GIS和CAD/CG系统的综合空间信息系统来考察大坂都市圈自然环境和社会环境的历史变迁。他们还试图描绘未来的淀川流域。具体地说，他们用这个系统形象地展示了从江户时代到现在的城市景观、桥梁景观和淀川河道的变化。此外，还弄清了淀岛对产业活动的影响和因素。吉川首席研究员开发了一个系统，该系统根据在现有地图上进行几何校正的历史地图生成3D城市模型。然后他将元禄时代大坂的典型城市景观和桥梁景观还原为3D-CG模型。特别是中之岛周边的桥梁景观，作为数字档案保存了可继承的优良历史环境。桥梁的CG模型，天马，天神，浪速，Kohrai，Ohe和Yodoya，在每个时代都有生成，并过渡可视化。他还选择了平片阶段，其中;江户的味道留在，并产生了目前的CG模型作为第一步。现在，他正准备通过互联网向公众公开这些数据。调查员阿亚利用明治初年发布的德赖克的调查图，还原了淀川的河流环境。他收集了现代测量技术建立后发布的测量图纸和地形图，并澄清了河流的变化。另一位调查员岩崎澄清了水路运输系统的历史变化和港口分布，以帮助淀岛上的工业。并对河流保护区作为城市游憩空间的现状进行了调查，明确了改善的任务。
