WorldView

A zero-cost prototype for a Palantir-style geospatial intelligence dashboard built with CesiumJS, public satellite TLEs, OpenSky aircraft data, and USGS earthquake feeds.

This project was inspired by the Spatial Intelligence project “I Built a Spy Satellite Simulator.”

Features

• 3D globe with OpenStreetMap imagery
• Live aircraft tracking via a same-origin /opensky endpoint
• Live satellite positions from CelesTrak TLEs
• Recent earthquakes from USGS
• Demo camera overlay
• Visual filters: CRT, Night Vision, FLIR

Local development

1) Install dependencies

If you are using Node locally:

npm install

2) Run the production-style local preview

npx wrangler pages dev public

This serves the static site and picks up the functions/ folder automatically.

3) Open the app

Visit the local URL shown in the terminal.

Production deployment

The recommended production setup is Cloudflare Pages + Pages Functions.

Steps

1. Push this repository to GitHub.
2. In Cloudflare Dashboard, create a new Pages project.
3. Connect the GitHub repository.
4. Set the build output directory to:

public

5. Set the build command to:

exit 0

6. Deploy.

Cloudflare Pages will serve public/index.html and automatically load the function in functions/opensky.js at /opensky.

Notes

• This project uses only public/open feeds.
• The OpenSky feed is proxied through the /opensky endpoint to avoid browser CORS issues.
• If OpenSky is unavailable, the UI falls back to simulated aircraft so the app still loads.
