Setting Up Fallback Tile Routing in Production
This guide walks through configuring a production reverse proxy so that tile requests degrade deterministically to a secondary backend when the primary…

Open-Source Geospatial Portal
Deployment & Scaling
Deploy, scale, secure, and maintain open-source geospatial platforms.
Running an open-source geospatial portal in production is a systems problem, not a single install. This is a practical, operations-first reference for the teams who keep GeoNode, MapProxy, TileServer GL and the wider OGC stack online — GIS administrators, open-source maintainers, platform engineers, and government technology teams.
Every guide is written for the realities of scale: zero-trust security boundaries, reproducible infrastructure-as-code, automated metadata pipelines, and CI/CD deployment patterns that survive traffic spikes and regional outages. The material is organised into three pillars, each drilling from architectural overview down to copy-ready configuration.
Start with a pillar below, or jump straight to a deep-dive. Code blocks are validated and copy-ready, navigation is cross-linked, and the whole site works offline once installed.
