OpenLayers
OpenLayers is a high-performance, feature-packed library for creating interactive maps on the web. It can display map tiles, vector data and markers loaded from any source on any web page. OpenLayers has been developed to further the use of geographic information of all kinds. It is completely free, Open Source JavaScript, released under the 2-clause BSD License (also known as the FreeBSD).
Getting Started
Use one of the following methods to use OpenLayers in your project:
-
For use with webpack, Rollup, Browserify, or other module bundlers, install the ol
package:
npm install ol
-
If you just want to add a <script>
tag to test things out, you can link directly to one of the full builds from cdnjs (not recommended for production)
-
For use with Closure Library (rare), install the openlayers
package and read the tutorial.
Supported Browsers
OpenLayers runs on all modern browsers that support HTML5 and ECMAScript 5. This includes Chrome, Firefox, Safari and Edge. For older browsers and platforms like Internet Explorer (down to version 9) and Android 4.x, polyfills for requestAnimationFrame
and Element.prototype.classList
are required, and using the KML format requires a polyfill for URL
.
