S2GOS

S2GOS (Sentinel-2 Ground Observation Simulator) is a modular Python framework for synthetic scene generation and Earth observation simulation. It enables the creation of physically realistic synthetic landscapes and simulates satellite, airborne, and ground-based sensor observations over them.

Packages

Package	Description
s2gos-generator	Synthetic scene generation: vegetation placement, terrain, land cover, and material configuration
s2gos-simulator	Observation simulation: radiative transfer via Eradiate, sensor models, illumination, and spectral configuration
s2gos-utils	Shared utilities: configuration, credentials, data access, and common data structures
s2gos-apps	Application workflows: process definitions for MTR demo, PnP, and multi-temporal radiometric demonstration

Quick Start

Installation

git clone git@github.com:s2gos-dev/s2gos-mono.git
cd s2gos-mono
pixi install
pixi run apps-init   # initialises Eradiate data (required once)

For development (adds testing, linting, docs tools):

pixi install -e dev
pixi run -e dev test
pixi run -e dev docs

Examples

Example	Description
HYPSTAR Gobabeb	Ground sensor simulations over the Gobabeb validation site driven by a real HYPERNETS L2A dataset

Configuration

S2GOS is configured via a s2gos_settings.yaml file placed in your working directory or any parent directory. See the s2gos-apps documentation for a full configuration reference.
