Keyhole Markup Language facts for kids

Keyhole Markup Language, or KML for short, is a special computer language that helps display information on maps. Think of it like a set of instructions that tells a map program where to put things and how they should look.

Just as a Web browser shows you web pages made with HTML, KML helps programs like Google Maps and virtual globes like Google Earth draw cool things on maps. It's like the secret code that makes maps come alive with details!

What is KML?

KML stands for Keyhole Markup Language. It's a file format, which means it's a specific way that computer information is saved. These files contain geographic data, like locations, paths, and shapes, along with details about them.

Imagine you want to show your friends where your favorite park is, or the route you took on a bike ride. KML can store that information so it can be easily shared and viewed on a map.

How KML Works with Maps

KML files are like blueprints for maps. When you open a KML file in a program like Google Earth, the program reads the instructions in the file. These instructions tell it:

• Where to place markers (like pins on a map).
• What shapes to draw (like outlines of countries or paths).
• How these items should look (their color, size, and even if they pop up with extra information).

This makes it easy to share and view geographic information in a visual way.

Who Uses and Manages KML?

KML is used by many people and organizations who want to share map data. You might have seen it in action if you've ever explored different layers or shared maps on Google Maps or Google Earth.

It's an international standard, which means it's a widely accepted way of doing things around the world. The Open Geospatial Consortium (often called OGC) is in charge of maintaining and updating the KML standard. They make sure KML works well for everyone.

Before the OGC took over, Google was the main company that looked after the KML standard. Google still has lots of helpful information about how to write KML on their website.
