What Is KML?
KML, which stands for Keyhole Markup Language, is an XML-based file format designed specifically for expressing geographic annotations and visualizations. It allows users to define points, lines, polygons, images, and overlays on maps, making geographic data easy to share and visualize. Originally developed for Google Earth, KML is now widely supported by various GIS (Geographic Information Systems) and mapping platforms, facilitating the integration of location-based information with rich descriptions and media.

It enables businesses, content creators, and marketers to visualize spatial data, which enhances decision-making and audience engagement. By using KML, you can effectively communicate location-based insights, improve local SEO strategies, and create immersive digital experiences that combine maps with storytelling elements.
