Introduction
In the past, maps were static and constrained in scope. Cartographers hand-drawn them on paper or parchment using tools like compasses and rulers to create detailed designs. As technology advanced, these maps were digitized into graphical formats and published on the websites. Today, interactive mapping technologies, such as Geographic Information Systems (GIS) and Mapping APIs, have transformed maps into dynamic tools and eliminated static limitations.
As reported on the Linearity website in 2023, “88% of marketers integrating interactive content into their strategies claim they gain better brand recognition and engagement”. In particular, this emphasizes the effectiveness of interactive elements on websites, such as maps, infographics, and data visualizations. Instead of passively receiving information, interactive maps simplify complex geographical data through color coding, animations, and customizations, enhancing user experience.
Interactive maps can enhance users' experience and interaction on websites. They allow users to manipulate and tailor the interface of several elements intuitively to update information quickly. Such features are helpful for non-profit organizations, businesses, and educational websites that need to showcase location-based relevant content.
This article will cover everything about interactive maps, including their types, how to create one, best design practices, and practical examples to help you implement them effectively on your website or application.

Step 1: Set Up the HTML Structure
Create a new HTML file named index.html and copy the following markup.
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Interactive Map with OpenStreetMap and Leaflet.js</title>
</head>
<body>
<h1>Interactive Map with OpenStreetMap and Leaflet.js</h1>
<div id="map"></div>
</body>
</html>
This line of code will create a div with id of map where the OpenStreetMap will be embedded.
Step 2: Include the Leaflet.js library in your project
Add the Leaflet.js CSS CDN link within the <head> section and the Leaflet.js JavaScript DN link right before the closing </body> tag.
To set the size of the OpenStreetMap, indicate the width and height of the map container using CSS inside the <style> tag.
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Interactive Map with OpenStreetMap and Leaflet.js</title>
<!-- Leaflet CSS -->
<link rel="stylesheet" href="https://unpkg.com/leaflet/dist/leaflet.css" />
</head>
<body>
<h1>Interactive Map with OpenStreetMap and Leaflet.js</h1>
<div id="map"></div>
<style>
h1 {
font-family: 'Poppins', sans-serif;
text-align: center;
}
/* Set the size of the map container */
#map {
width: 100%; /* Set the width to 100% of the container */
height: 600px; /* Set a specific height for the map */
}
</style>
<!-- Leaflet JavaScript -->
<script src="https://unpkg.com/leaflet/dist/leaflet.js"></script>
</body>
</html>
Step 3: Initialize and add the tiles for OpenStreetMap
Add the following code after the Leaflet.js JavaScript CDN link (placed just before the closing </body> tag).
This code initializes an OpenStreetMap instance, sets its view to a specific location and zoom level, and loads map tiles provided by OpenStreetMap.
// Initialize the map and set its view to a specific location and zoom level
const map = L.map('map').setView([36.7854, -119.7922], 15); // Coordinates: Latitude, Longitude; Zoom level: 13
// Add OpenStreetMap tiles to the map
L.tileLayer('https://{s}.tile.openstreetmap.org/{z}/{x}/{y}.png', {
attribution: '© OpenStreetMap contributors',
}).addTo(map);
Note: The coordinates used in the code above represent Fresno, California, USA. You can replace them with the coordinates of any location you prefer.
Step 4: Add Map Interactivity Functions for Leaflet.js
In addition to the basic map setup, you can improve OpenStreetMap's interactivity by adding a Leaflet.js pop-up marker function at a specific location. This will allow users to click on the marker and view additional information about the area.
Add the following code to the OpenStreetMap's tiles codes to implement this.
// Add a marker to the map at the same location
const marker = L.marker([36.7854, -119.7922]).addTo(map);
marker.bindPopup("<b>EAST GARLAND AVENUE</b><br>This is the location marker for <br/>East Garland Avenue Parking Lot. ").openPopup();
Another useful Leaflet.js feature is highlighting a specific location through a circle overlay function. A pop-up marker with information about that location will appear when users click on the circle.
You can include the following code after the pop-up marker function:
// Add a circle overlay to a different location
const circle = L.circle([36.787833, -119.782712], {
color: 'red',
fillColor: '#f03',
fillOpacity: 0.5,
radius: 100,
}).addTo(map);
circle.bindPopup("<b>MANCHESTER GATE ELEMENTARY SCHOOL</b><br>This is a circle overlay for <br/>Manchester Gate Elementary School.");
Helpful Tips: To learn additional functions and features for this map, explore the OpenStreetMap and Leaflet.js documentation for more interactive options.
