Description

Processing Device and Processing Method for Simulation Data on Terrain The present disclosure relates to an apparatus and a method for processing simulation data regarding terrain. Topographic data is considered a crucial element in various modern industrial sectors. In particular, technologies for acquiring and analyzing accurate topographic data are essential not only for Geographic Information Systems (GIS) but also for autonomous vehicles, robotics, civil engineering, military operations, the gaming industry, and architecture and environmental engineering. Topographic data is generally collected through radar, LiDAR, aerial photography, satellite data, drones, etc., and three-dimensional (3D) topographic models are constructed based on this data. Various forms of simulation data can be applied to a 3D terrain model. For example, simulation data related to natural phenomena such as precipitation, monsoon, typhoons, or landslides can be applied to a 3D terrain model. However, when simulation data is applied to visualize a conventional 3D terrain model, there was a problem with reduced readability and visibility compared to a 2D terrain model.
