Digital Urban Environment Project for Analyzing the Impact of Shadow, Wind, and Noise
12-01, 14:10–14:30 (Asia/Seoul), Seoul Archive

The Digital Urban Environment project “toENG” aims to analyze the influence of shadow, wind, and noise on the urban environment . The project incorporates functionalities for user management, allowing users to create workspaces and projects to conduct analyses.

Within the project, users can select specific services for analyzing shadow, wind, and noise within their chosen area. Currently, the project is capable of analyzing shadow based on the 3D architecture of buildings.

To analyze shadow in the urban environment, users follow these steps: they select the shadow analysis option and specify the analysis area on a 2D map. They input analysis parameters such as the time of day for the analysis and the duration of the study. The analysis results are then presented through czml files, displaying the levels of shadow influence.

After completing the analysis, users can upload the 3D architecture of buildings in either IFC or 3D-tiles format. The analysis results and user-uploaded data are linked to “Re:Earth”, allowing visualization on a 3D map.

“toENG” project provides valuable insights into the interaction between environmental factors and urban spaces, aiding in informed decision-making and sustainable urban planning.

After graduating from Danang University of Science and Technology in 2016, I joined Applied Technology Co., Ltd. in 2018 as an engineer specializing in environmental systems. I worked on projects including a 3D viewer using mago3D for the National Institute of Advanced Industrial Science and Technology, CEARD-AR disaster education app, and railway disaster information system. Currently building "" service with Re:Earth and PLATEAU data.

Hirofumi Hayashi (aka Hayashi) became an OSGeo Charter member in 2010, and is a longtime member of the Board of the OSGeo-Japan chapter.
Hayashi is a Manager for a large engineering company in Osaka Japan (Applied Technology Co.), and yet still finds time to contribute to the vibrant OSGeo-Japan community.
