Getting Started

Prerequisites

Node.js ≥ 18
npm ≥ 9

Installation

# Clone the repository
git clone <repository-url>
cd worldview

# Install dependencies
npm install

Environment Setup

⚠️ This repo does NOT ship any API keys. You must obtain your own.

Copy the example files and fill in your credentials:

cp .env.example .env
cp server/.env.example server/.env

Then edit each file with your own API keys (see Obtaining API Keys below).

.env — Client-side (Vite injects VITE_* variables at build time):

Variable	Required?	Purpose
`VITE_GOOGLE_API_KEY`	Optional	Google Maps 3D Photorealistic Tiles (falls back to OpenStreetMap)
`VITE_CESIUM_ION_TOKEN`	Optional	Cesium Ion terrain/imagery services
`WINDY_API_KEY`	Optional	Windy webcam API (reserved, not yet active)
`NSW_TRANSPORT_API_KEY`	Optional	Transport for NSW CCTV cameras
`AISSTREAM_API_KEY`	Optional	AISStream.io global AIS ship tracking

server/.env — Server-side (loaded by dotenv):

Variable	Required?	Purpose
`GOOGLE_MAPS_API_KEY`	Optional	Server-side Google Maps (currently unused)
`OPENSKY_CLIENT_ID`	Optional	OpenSky Network OAuth2 credentials
`OPENSKY_CLIENT_SECRET`	Optional	OpenSky Network OAuth2 credentials
`AISSTREAM_API_KEY`	Optional	AISStream.io global AIS ship tracking

All layers degrade gracefully when keys are missing — the globe falls back to OpenStreetMap, CCTV sources without keys are simply skipped, and external APIs that don't require auth (USGS, CelesTrak, adsb.fi) work without any credentials.

Obtaining API Keys

🗺️ Google Maps API Key (for 3D Photorealistic Tiles)

Go to the Google Cloud Console
Create a new project (or select an existing one)
Navigate to APIs & Services → Library
Enable the Map Tiles API
Go to APIs & Services → Credentials → Create Credentials → API Key
IMPORTANT — Restrict your key immediately (see Securing Your Google API Key below)
Copy the key into VITE_GOOGLE_API_KEY in your .env file

Google offers a US$200/month free tier which covers approximately 25,000 3D Tiles loads. For personal/demo usage this is typically more than enough — but set a budget alert just in case.

🛰️ Cesium Ion Token (optional)

Sign up for a free account at cesium.com/ion
Go to Access Tokens → copy your default token
Paste into VITE_CESIUM_ION_TOKEN in your .env

📹 Transport for NSW API Key (for Australian CCTV cameras)

Register at opendata.transport.nsw.gov.au
Go to My Applications → Create Application
Subscribe to the Traffic & Cameras API
Copy your API key into NSW_TRANSPORT_API_KEY in your .env

🚢 AISStream.io API Key (for Naval / AIS ship tracking)

Sign up for a free account at aisstream.io
Log in → navigate to your Dashboard
Generate an API key
Paste into AISSTREAM_API_KEY in both .env and server/.env

The free tier provides access to the global AIS WebSocket stream. The backend uses a "burst" pattern — connecting for 20 seconds to collect vessel data, then caching results for 60 seconds — to stay well within Vercel's serverless function timeout.

✈️ OpenSky Network (optional, for WebSocket flight data)

Register at opensky-network.org
Log in → go to OAuth → Create Client
Copy the client ID and secret into server/.env

Running the Application

# Start the backend proxy server (port 3001)
npm run dev:server

# In a separate terminal, start the Vite dev server (port 5173)
npm run dev

# Or start both at once
npm run dev:all

Open http://localhost:5173 in your browser.

Note: The backend proxy server must be running for data layers to function. Vite's dev server proxies all /api/* requests to localhost:3001.

Production Build

npm run build
npm run preview

Deploying to Vercel

This project is pre-configured for Vercel via vercel.json. The Express backend runs as a Vercel Serverless Function.

1. Import the Project

Push your repo to GitHub
Go to vercel.com/new → Import Git Repository
Select your repo → Vercel auto-detects the Vite framework from vercel.json
Click Deploy

2. Set Environment Variables

In your Vercel project dashboard:

Go to Settings → Environment Variables
Add each key from both .env files:

Variable	Environment
`VITE_GOOGLE_API_KEY`	Production, Preview
`VITE_CESIUM_ION_TOKEN`	Production, Preview
`WINDY_API_KEY`	Production, Preview
`NSW_TRANSPORT_API_KEY`	Production, Preview
`GOOGLE_MAPS_API_KEY`	Production, Preview
`OPENSKY_CLIENT_ID`	Production, Preview
`OPENSKY_CLIENT_SECRET`	Production, Preview
`AISSTREAM_API_KEY`	Production, Preview

Note: VITE_* variables are embedded in the client bundle at build time. Server-side variables are available to the serverless function at runtime.

Data Flow

React hooks poll the Express proxy server at layer-specific intervals
Express caches upstream API responses, manages OAuth2 tokens, and hides credentials
App.tsx manages global state — layer visibility, camera position, tracked entity, shader mode
Layer components receive data via props and render imperatively into the Cesium scene
UI components display controls, feeds, and status information as React DOM overlays

Dual Flight Data Strategy

WorldView merges two aircraft data sources for optimal coverage:

Source	Coverage	Update Rate	Data Richness
FlightRadar24	Global (7 zones)	20 s	Origin/destination airports, airline
adsb.fi	Regional (250 NM radius)	5 s	High-frequency position updates

When zoomed out: FR24 global data only
When zoomed in: adsb.fi replaces FR24 for nearby aircraft (deduplicated by ICAO24)
Route info from FR24 is cross-referenced to enrich adsb.fi data

Features in Detail

🎯 Entity Tracking

Click any entity on the globe to lock the camera onto it. The view follows the entity in real-time with an appropriate offset:

Aircraft — 50 km trailing offset with heading alignment
Satellites — 200 km offset for orbital viewing
Earthquakes — 100 km overhead view of the epicentre
Ships — 20 km offset at low angle with heading alignment
CCTV cameras — 2 km offset at 45° viewing angle

Press ESC to unlock tracking without moving the camera.

Adding a New Data Layer

Create a hook in src/hooks/ — fetch data from the backend, return typed state
Create a layer component in src/components/layers/ — render Cesium primitives
Add a proxy endpoint in server/index.js — cache upstream API, hide credentials
Wire into App.tsx — add layer toggle state, invoke hook, pass data to layer component
Update OperationsPanel — add toggle control for the new layer
Update StatusBar — add entity count display

Performance Guidelines

Use imperative Cesium primitives (BillboardCollection, PointPrimitiveCollection) for layers with >100 entities
Avoid creating Resium <Entity> elements in loops for large datasets
Use useCallback and useMemo liberally — the Cesium render loop is sensitive to reference changes
Prefer CallbackProperty over React state for Cesium entity positions
Implement dead-reckoning for moving entities to maintain 60 fps between data updates

Troubleshooting

Issue	Solution
Blank globe / no tiles	Check `VITE_GOOGLE_API_KEY` is valid with Maps JavaScript API enabled; the app falls back to OSM automatically
No flight/satellite/earthquake data	Ensure the backend proxy is running (`npm run dev:server`)
CCTV images not loading	Backend must be running to proxy images through `/api/cctv/image`
"429 Too Many Requests" in console	Upstream API rate limit hit; the cache layer reduces frequency, wait for TTL to expire
Overpass API timeout	Traffic layer falls back to static Sydney CBD road data
Satellites not appearing	TLE API may be temporarily down; CelesTrak is used as automatic fallback
Ships not loading / empty layer	Ensure `AISSTREAM_API_KEY` is set in `server/.env`; initial load takes ~20 s while the burst WebSocket collects data
Only a few ships visible	Toggle off the moving-only filter by removing `?moving=1`; some regions have less AIS coverage
Google 3D tiles error	API key may be invalid or quota exceeded; OSM is applied automatically
