Explore our new WebGIS viewer showcasing a Europe-scale 2.5 m super-resolved Sentinel-2 data cube generated with LDSR-S2 and directly comparable to the native 10 m imagery.

OpenSR-SRGAN is our new open-source framework that makes GAN-based super-resolution easy, modular, and fully reproducible for multispectral satellite data. It lets researchers swap architectures, losses, and training strategies through simple configuration files—no code changes needed.

The ESRI Analytics Team has integrated our model into ArcGIS! Users can now easily and seamlessly use our models straight without coding, straight through their GIS software.

NIR-GAN: Synthesizing Near-Infrared from RGB with Location Embeddings and Task-Driven Losses We’re excited to share that our work, “Near-Infrared Band Synthesis From Earth Observation Imagery

Luis Gómez Chova and César Aybar represented OpenSR at the 4th IADF School in Benevento, delivering sessions on super resolution and EO machine learning.

This demo, aimed at non-technical users, allows you to enter your coordinates and create a super-resolution product on your custom Sentinel-2 acquisition. Immediately judge wether SR can be useful for you application!

The OpenSR team joined ESA’s Living Planet Symposium 2025 to present our latest advances in Sentinel-2 super-resolution, dataset standards, and workflows. From latent diffusion models to FAIR-compliant data access with TACO, our tools aim to make high-resolution Earth observation more accessible and actionable.

A lightweight validation toolkit to benchmark segmentation performance across low-, super-, and high-resolution imagery. Quantifies how well super-resolution models improve object detection and segmentation accuracy in real-world tasks. Ideal for researchers who want to go beyond visual inspection and measure actual downstream performance gains.

We’ve published a new preprint presenting SEN2SR, a deep learning framework for super-resolving Sentinel-2 imagery with radiometric and spatial fidelity. The model leverages harmonized synthetic data, hard constraints, and xAI tools to achieve artifact-free enhancements at 2.5 m resolution.

Our Latent diffusion model, including weights, for the RGB-NIR bands of Sentinel-2 has been released.

Our diffusion-based super-resolution model for Sentinel-2 imagery has been published in IEEE JSTARS! The open-access paper introduces a latent diffusion approach with pixelwise uncertainty maps—pushing the boundaries of trustworthy generative modeling in Earth observation.

We’ve released SEN2NAIP v2.0, a large-scale dataset designed for training and validating super-resolution models on Sentinel-2 imagery. The dataset includes thousands of real and synthetic HR-LR image pairs, making it a cornerstone for future SR research in Earth Observation.

The dataset paper has been published in ‘Scientific Data’.

Our team at the University of Valencia has released an interactive satellite flood map of the recent Valencia flash floods, using Landsat-8 and Sentinel-2 imagery combined with a machine learning segmentation model. Leveraging super-resolution techniques, we enhanced Sentinel-2 data to 2.5m resolution, enabling more precise flood extent mapping for post-disaster analysis.

We’ve released a preview of OpenSR-Utils, a Python package to apply super-resolution models on raw Sentinel-2 imagery. With multi-GPU support, georeferenced output, and automatic patching, it’s a practical toolkit for real-world remote sensing pipelines.
