Cover Story: Thanks to the availability of geospatial data, 3D environment reconstruction has been used in the visualization of urban environments. OpenStreetMap offers a huge potential by providing a flexible, crowdsourced alternative to use for such purposes. In this work, City Maker, a 3D environment reconstruction tool, was designed to use OpenStreetMap as the map data source to generate digital city models. By providing additional parameters such as roughness coefficients and storm drains, the digital city model was made simulation-ready. By arranging the layers in an appropriate format, the city models were loaded and visualized efficiently. The model was tested with a hypothetical flooding scenario to demonstrate its applicability. It is also noted that given data availability, OpenStreetMap can be used to generate digital city models. View this paper.
