• 📍 Drop Pins: Click anywhere on the map to add a pin with a custom note.
• 📝 Categorize Notes: Use built-in labels (Geology, Climate, Demographic, Culture, House Market, General) or create your own custom labels.
• 🔍 Search & Filter: Search pins by text or filter them by label.
• 🌐 Location Context: Pins automatically fetch country, region, and formatted address using Google Maps API.
• 🪨 Geological Data: Fetch stratigraphic and lithological information from the Macrostrat API.
• 🦕 Fossil Records: Display paleontological data from the Paleobiology Database (PBDB).
• 💾 Persistent Storage: Pins are stored in pins.json (file-based) and served through a Node.js/Express backend.
• 🎨 Responsive UI: Clean sidebar and notes panel with search, filtering, and styled data panels.

• Frontend: HTML, CSS, JavaScript (Google Maps API)

• Backend: Node.js, Express, CORS, dotenv

• Database: File-based JSON storage (pins.json); optionally connect MongoDB via MONGO_URI

• External APIs:

  • Google Maps Geocoding
  • Macrostrat Geological API
  • Paleobiology Database (PBDB)

git clone https://github.com/your-username/geonotes.git
cd geonotes

cd backend
npm install

• Create a .env file:

MONGO_URI=mongodb://localhost:27017/geonotes
PORT=3001

GOOGLE_API_KEY= YOUR_API_KEY

for Google API, go onto Google Map Platform and sign up.

• Start the server:

npm run dev   # with nodemon
npm start     # without nodemon

Server will run at: http://localhost:3001

cd ../frontend
npm install

• Start the development server:

npm run dev

Frontend runs at: http://localhost:3001

1. Open the frontend in your browser.
2. Click anywhere on the map to add a pin.
3. Add a note, select a label, or create a custom category.
4. Explore geological and fossil data fetched from external APIs.
5. Use the sidebar to search, filter, and manage your pins.

• Switch to online database by creating a cluster at MongoDB Atlas.
• Deploy on website
• Add user authentication and personal pin collections.
• Enable sharing pins with friends or exporting them.
• Add climate and demographic APIs for richer context.
