The stac-gis workspace: map, catalog, dashboards, and the AI agent chat.

Three components, one platform

Use any piece standalone - or combine them into a self-hosted, AI-powered geospatial platform.

Core

The STAC-compliant platform: FastAPI + React, PostgreSQL (PostGIS + pgvector), MinIO storage, async GIS processing - and a full map-centric application with AI chat.

Core docs →

Geo-AI

A reusable harness for geospatial AI agents: ReAct loop, MCP tools, local LLMs via Ollama, FastAPI streaming, and the <AgentChat /> React component.

Geo-AI docs →

Catalog

A Python toolkit (stac-catalog) that turns raster metadata (CSV or Google Sheets) into STAC Collections and Items, loads them into pgSTAC, and serves them via STAC FastAPI, TiTiler, and a ready-made STAC Browser.

Catalog docs →

A pragmatic geospatial stack

Standard, boring technology where it counts - and modern, standards-based building blocks (STAC, OGC, MCP) where it matters.

stac-gis - a STAC-compliant, AI-powered geospatial platform.

Up and running in minutes

Clone Core, copy the example environment, and bring up the full stack - web apps, backend, database, cache, object storage, and the AI runtime - with Docker Compose. Point the Catalog at the STAC API and you have a complete platform.

Installation guideExplore the architecture
# 1. Get the code
git clone https://codeberg.org/stac-gis/core.git
cd core

# 2. Configure
cp backend/stacgis/.env.example backend/stacgis/.env
cp fronted/apps/stacgis/.env.example fronted/apps/stacgis/.env

# 3. Launch the full stack
docker compose up -d --build

# 4. (Optional) build a STAC catalog with stac-catalog
stac-catalog sync --source csv --input ./input --output ./output
