OpenFreeMap is an OpenStreetMap vector tile server and distribution system designed for self-hosted map tile infrastructure. It provides a platform for deploying and managing full-planet map datasets on independent server infrastructure, delivering map data as vector tiles.
The system distinguishes itself by distributing pre-processed map data as standard filesystem images, allowing for the mounting of full-planet extracts without the need for a live database. It utilizes a static file serving model and a vector tile distribution system that provides weekly updates in image formats for local hosting.
The project covers a broad range of capabilities including map style rendering and customization, where visual appearances are determined by style specifications. It also encompasses traffic management through round-robin DNS load balancing and health monitoring to support high-availability map hosting.
