DTE-S2GOS components

DTE-S2GOS 3D Synthetic Scene Generator

General approach

The 3D Synthetic Scene Generator (SSG) is one of the core components of DTE-S2GOS. It relies on scene configuration parameters and external datasets to generate a scene description and the associated 3D assets. The level of realism and detail of the generated scenes depends on the availability and quality of the input information.
Observation Simulator

General concept

The DTE-S2GOS simulator relies on Eradiate, a state-of-the-art 3D radiative transfer model, to accurately simulate observations acquired by satellite- and ground-based radiometers. It supports both multispectral instruments, such as Sentinel-2/MSI, and hyperspectral instruments, such as CHIME and HYPSTAR-XR, offering users a high degree of flexibility in configuring instrument characteristics and observation conditions.
