What is a KML File and Why Use It?
A KML (Keyhole Markup Language) file is a format used to display geographic data — such as points, lines, and polygons — on maps like Google Earth and Google Maps. With a KML Viewer, you can easily open these files to visualize locations, paths, and boundaries without needing desktop software like Google Earth.
Key Components of KML Files:
- Placemarks: Points of interest with coordinates and descriptions
- Paths: Lines and routes connecting multiple points
- Polygons: Areas and boundaries with defined shapes
- Folders: Organized collections of geographic elements
