I'll create a web application that uses the Geolocation API to get your current location and displays it on a map with surrounding areas using the Google Maps JavaScript API.

To use this application, you'll need to:

1. Replace "YOUR_API_KEY" in index.html with an actual Google Maps JavaScript API key
2. The app will show your current location when you click "Locate Me"
3. Click "Scan Area" to find nearby places like restaurants, parks, etc. within 500 meters
4. Click on any marker to see more information about that place

Note: For this to work properly, you'll need to:

• Enable the Google Maps JavaScript API and Places API for your API key
• Ensure your browser supports geolocation
• Grant location permissions when prompted
