TerraFuse

Open-source geospatial fusion for DGGS-native analysis and common operating pictures.

TerraFuse is an early prototype of a drag-and-drop web environment for geospatial data fusion. The first slice focuses on H3-backed cell aggregation, Cesium globe visualization, and a full-stack project shape that can grow into server-side ingest, analysis, collaboration, and operator-room workflows.

Prototype Features

• Drag and drop CSV, GeoJSON, or JSON files.
• Auto-detect latitude/longitude, value, timestamp, and category-like fields.
• Convert records into H3 cells at selectable resolution.
• Render fused cell layers as geospatial polygons on a Cesium globe with an OpenStreetMap basemap.
• Toggle individual datasets on/off before fusion.
• Switch between street and satellite basemaps.
• Compare uploaded datasets by shared cell and fused score.
• Switch into a touch-oriented common operating picture layout.

Run Locally

npm install
npm run dev

The web app runs on http://localhost:5173. The API runs on http://localhost:8787.

Project Shape

• apps/web: React, Vite, CesiumJS globe UI.
• apps/api: Express API skeleton for future ingest/workspaces.
• packages/core: Shared DGGS indexing and fusion logic.
