Procedural Terrain Creation Using Satellite Imagery and Digital Elevation Model (DEM)


Procedural Terrain Creation Using Satellite Imagery and Digital Elevation Model (DEM)



Supports terrain rendering and system load minimization through multi-layered terrain



Open world-based terrain creation

Streaming terrain information and images through a terrain generation server

Georeferencing corresponding to various coordinate systems




Open world-based terrain creation

Unlike topography creation and processing through a simple height map, it combines satellite imagery, orthographic projection, and numerical elevation model data to create a multi-layered topography like the real geography, and through this, high-quality topography similar to the real topography is displayed in the open world do. The multi-layered terrain created in this way can be optimized in various ways, such as LOD and HLOD, depending on the production method, and is created to minimize the system load in addition to rendering the terrain with a quality similar to reality.

Terrain information and image streaming through terrain generating sub

Streams and visualizes terrain information and images based on the user's field of view in real time through a terrain generation server that streams tiled terrain in phases in real time.

Image streaming visualization based on user's field of view




Georeferencing corresponding to various coordinate systems

The Georeferencing function provided by Unreal Engine not only creates a terrain that is visually similar to reality, but also converts and displays in real time the location of an object moving on the ground or in the air in the plane coordinate system or the spherical coordinate system. It is widely used in digital twins and simulators.

Utilization of generated terrain

Terrain mapping and terrain visualization techniques applied with tiling techniques based on satellite maps are applied to build a variety of XR integrated solution environments. It is being actively used for solutions that require realistic depiction and manipulation, such as flight control simulators and digital twin-based port control systems, and provides an immersive experience by supporting terrain rendering and minimizing system load.
