Open-source geospatial infrastructure — March 2026

Geospatial data shouldn't be
locked behind a license.

This project builds a fully self-hosted, open-source spatial data platform — so researchers and students can publish maps, run spatial queries, and share geographic data freely, without Esri contracts or institutional gatekeeping.

Most university GIS infrastructure runs on Esri. That means every map you publish, every dataset you share, and every API you build depends on a license your institution controls — and can revoke. When the contract lapses or you graduate, your work goes dark.


Why it matters

01

For researchers

Publish spatial findings to the open web — no licensing restrictions, no barriers between your work and your audience.

02

For students

A shared platform to contribute to, build on, and learn from. Real infrastructure, not a classroom sandbox.

03

Built for AI

Spatial APIs that plug directly into AI workflows — RAG pipelines, LLM grounding, agent tool calls, and custom model context. Geography as a first-class data source.

The core data layer is running. The next step is serving vector tiles and standing up the public-facing API. Looking for collaborators — whether you want to contribute code, test with your own datasets, or just follow along.
