What is KML?
KML is nothing but a file format that is used for displaying geographic data in earth browsers such as Google maps and Google earth. KML makes use of an XML structure that has attributes and nested elements.
How to create KML files?
Three main tools are used to create KML files. They are as follows:
Google Earth: This is a very important tool that can be effectively used for creating KML files. With the help of Google Earth software, you can create polygons, paths, place marks, network links, place models, and image overlays.
1) When you create any of these objects mentioned above, right click on the object in “Places” pane and then select” Copy”. You should then paste it into an XML editor or a text editor and start editing it.
XML editors: KML is a XML language that is used to describe geographic content. XML editors provide lot of tools to create XML documents such as tag completion, which ensure that, do not forget to close XML elements with proper close tags.
How to open KML files?
A KML file contains compressed collection of 1 or more files to view in Google Earth. Using zip format, they are compressed and you can open them using any zip tool that include “WinZip” or with Windows XP compressed folder tool, “zip” for Linux or Mac OS, “Stuffit” for Mac OS. The file extension can also be changed from *.kml to *.zip. A zip tool will be able to easily recognize a file whose extension is changed to .zip. But you will have to change it back to.kml before using the file.
Why KML files do not download correctly from the webserver?

Browsers such as Internet explorer completely rely on Web server's TYPE settings. If you are managing your own web server then you need to modify your own configuration.
