1. 6. Streamlining 3D City Modeling for Urban Flow Simulations by Automatic Integration of Multisource Topography

   University essay from Umeå universitet/Institutionen för fysik

   Author : Klara Lindroth; [2023]
   Keywords : automatic 3D city models; surface reconstruction; geometry pre-processing; CFD; OSM height attributes;

   Abstract : In the workflow of computational fluid dynamics, geometry preparation is commonly the most time-consuming step. For a fast CFD simulation, automatic surface reconstruction to obtain 3D city models for a chosen area is essential. To address this need, a literature study was conducted to map available data suitable for 3D city models. READ MORE
