Development of 3D Automatic Building Parcel Model for Urban Heat Simulation Analysis Environments

In this study, we developed an algorithm to 3D buildings within usable pacel information by changing the occupancy rate, volume ratio, height, etc. of buildings to enable simulation in various environments.. This algorithm to create a 3D building model in a parcel that can be used in performing an urban heat island simulation. By using the information on parcels within the legal limits, a 3D building model creates a building that can be constructed to the maximum for each parcel. The algorithm was applied for parcels in Seogyo-dong, Mapo-go, Seoul, and after about 30 minutes, buildings were found to be created in all parcels.
