Development of Green Space Evaluation Method from which Seen-Environment is considered and Effect of Preservation of Natural Landscape by Integrating three dimensions GIS and VR

本研究从城市空间三维模型的构建入手。利用地理信息系统和VR系统，进行了以下工作：1)开发了用于检查绿地和行道树布置的VR系统；2)开发了用于检查墙面和屋顶花园绿化的VR系统；3)开发了用于检查城市规划中的空间构成要素的辅助工具开发；4)开发了绿地环境信息库的开发。首先，开发了10号路(北戴国道)、197号路(大田体育公园附近)和“宇豪口恩街”的VR系统，包括绿地布置(树的布置和消除)和街道宽度等操作开发了墙体和屋顶绿化检查的VR系统，并提出了非专家参与设计的系统。绿地景观构成要素(建筑、绿化等)第四，构建了绿地环境信息数据库，了解了《绿色总体规划》中各分区的特点。其次，根据视觉信息对绿地影像进行分类，明确了《绿色总体规划》中确定的各区域的绿色功能比例。最后，总结了下一步的任务和愿景。

In this research, it started from the construction of three-dimensional model in urban spaces. GIS and the VR system were used, and the following actions were executed.1)VR system development for examining green space and street trees arrangement2)VR system development for examining greening on wall and rooftop gardening.3)Supporting tool development for arrangement for examining spatial composition element in city planning4)Development of Green Space Environmental Information DatabaseFirstly, the VR system of the Route 10 (Betsu-Dai National Road), the Route 197 (vicinity of the Oita sports park), and the "Yuho Kouen Street" including manipulations of the arrangement of green areas (arrangement and elimination of the tree) and widths of street, etc. was developed.Secondly, the VR system examining greening on the wall and rooftop was developed.Thirdly, the system by which the non-specialist was able to participate in the design was proposed. The green space landscape composition element (building and green, etc.) is operated in the system.Fourthly, a green space environmental information database was constructed, and features of each zone in "Green Master Plan" were understood. Next, the green space photograph was classified based on the visual information, and the proportion of a green function of each zone decided in "Green Master Plan" was clarified.Finally, future tasks and the visions were summarized.
