What is a KML File?
A KML (Keyhole Markup Language) file is a file format used to display geographic data in a web browser or GIS software. It’s the same format used for Google Earth and Google Maps. KML files contain information about the location, shape, and properties of geographic features, such as points, lines, and polygons. In the context of topographic maps, KML files provide detailed elevation data, contour lines, and other features that help you understand the terrain you’re exploring.
