- * Upload photos
- * Choose custom marker colors and icons
- – Click “Save” to add the point
- 4. Add Multiple Points Efficiently
- – Import Spreadsheet Data: Click “Import” to upload CSV, Excel, or Google Sheets files containing addresses or coordinates
- – Layer Organization: Create separate layers for different point categories (e.g., “Restaurants,” “Hotels,” “Attractions”)
- – Batch Editing: Select multiple points to change their icon style simultaneously
- 5. Customize Point Appearance
- – Click any point to open its information window
- – Select “Style” (paint bucket icon)
- – Choose from:
- * Uniform style (all points look identical)
- * Sequence of colors/letters/numbers
- * Individual styles (each point unique)
- * Style by data column (color-code by category)
- 6. Share and Embed Your Map
- – Click “Share” to adjust privacy settings (Public, Anyone with link, Private)
- – For website embedding:
- * Click the three-dot menu
- * Select “Embed on my site”

Bulk Import with Google Sheets Integration
For larger datasets or regularly updated points, spreadsheet integration provides efficiency.
Implementation Guide:
- 1. Prepare Your Data in Google Sheets
- – Create columns with these headers (minimum requirements):
- (Location Name | Address | Latitude | Longitude | Category | Description)
- 2. Geocode Addresses to Coordinates
- – Use the `GOOGLEMAPS` function in Google Sheets (requires API or add-on)
- – Or use free geocoding services like [OpenCage](https://opencagedata.com) or [Nominatim](https://nominatim.org)
- – Copy-paste coordinates into your spreadsheet
- 3. Import to Google My Maps
- – In My Maps, click “Import”
- – Select your Google Sheets file
- – Choose the column to use for location titles
- – Select the column for placemarks
- 4. Automate Updates with Scripts
- – Use Google Apps Script to automatically sync data
- – Set time-based triggers for daily/weekly updates
- – Implement webhook receivers for real-time updates
Advanced Spreadsheet Technique:
javascript
// Sample Google Apps Script for automatic updates
function updateMapPoints() {
var sheet = SpreadsheetApp.getActiveSpreadsheet().getSheetByName("Locations");
var data = sheet.getDataRange().getValues();
// Process and send to mapping service
// This is a conceptual example - actual implementation varies by service

async function addPointByAddress(address, title, description) {
const geocoder = new google.maps.Geocoder();
geocoder.geocode({ address: address }, (results, status) => {
if (status === 'OK') {
const location = results[0].geometry.location;
addPoint(location.lat(), location.lng(), title, description);
} else {
console.error('Geocode failed:', status);
}
});
}Code language: JavaScript (javascript)- 3. Drawing Shapes and Areas:
- javascript
// Draw a circle around a point
function drawRadius(pointLat, pointLng, radiusMeters) {
const circle = new google.maps.Circle({
strokeColor: "#FF0000",
strokeOpacity: 0.8,
strokeWeight: 2,
fillColor: "#FF0000",
fillOpacity: 0.35,
map: map,
center: { lat: pointLat, lng: pointLng },
radius: radiusMeters
});
}Code language: JavaScript (javascript)Step 4: Optimization and Best Practices
