Transforming Earth observation data visualization through cloud-native GeoZarr format

🌐 Visit EOPF Explorer | 🔗 API Documentation

EOPF Explorer is a transformative visualization service for Earth Observation Processing Framework (EOPF) Sentinel data in the revolutionary GeoZarr format. Led by Development Seed in partnership with EOX and Simula Research Laboratory, this project establishes a new standard for cloud-native Earth observation data visualization.

The EOPF Zarr format represents a paradigm shift from traditional SAFE formats to cloud-optimized storage, enabling millisecond-response visualization of massive Earth observation datasets while maintaining scientific accuracy and integrity.

• Web-Optimized Zarr (WOZ) - Spearheading the development of WOZ profile within the GeoZarr community
• High-Performance APIs - Millisecond-response visualization services supporting OGC standards
• Story-Driven Showcases - Compelling narrative experiences highlighting real-world applications
• Community-First Development - Open-source, collaborative approach with key ecosystem contributors
• Cloud-Native Architecture - Scalable microservices deployment on Kubernetes

Our cloud-native architecture consists of several interconnected components:

• 🗺️ Visualization Service - High-performance web APIs for data visualization
• 📊 Managed GeoZarr - Systematic approach to creating and maintaining optimized datasets
• 🔍 Cataloging Service - STAC metadata catalog integration
• 🌐 Tiling Service - Dynamic tiling of raster data for optimal performance

• 🔄 Data Pipeline - Automated transformation from EOPF to Web-Optimized Zarr
• 📈 Coverage Service - Time series extraction and analysis capabilities
• 💾 Object Storage - Scalable GeoZarr data storage on cloud infrastructure

GeoZarr-compliant data model for EOPF datasets, ensuring full compliance with GeoZarr spec 0.4 while maintaining native coordinate reference systems and multiscale support.

High-performance TiTiler application specifically designed for EOPF datasets, providing fast visualization APIs with OGC compliance and S3 compatibility.

Automated pipeline for converting STAC Items and existing Zarr stores into GeoZarr format on S3, with orchestration via Argo Workflows and AMQP message triggers.

Modern, responsive landing page showcasing EOPF Explorer capabilities and providing access to documentation and resources.

Terraform-based infrastructure deployment for Kubernetes clusters on OVH Cloud, supporting the scalable cloud-native architecture.

FluxCD-enabled repository for managing Kubernetes deployments with GitOps practices, including sealed secrets and automated reconciliation.

Content management system for creating and managing story-driven showcases and educational narratives about EOPF Explorer capabilities.
