Keyhole Markup Language (KML)

What is KML?

• KML stands for Keyhole Markup Language.
• Used for managing three-dimensional geospatial data in

Google Earth and Google Maps

• It is also supported to varying degrees by other virtual

Globe programs (e.g., NASA World Wind, ESRI ArcGIS

Explorer).

• Examples and documentation on KML can be found on the

official Google Earth webpages:

Authoring KML

• You can open a KML file with any text editor, such as

Microsoft Word or Notepad on using nedit on a Unix system.

• When creating your own KML file it must start with standard

header lines:

• and end by with a closing kml tag:
• If you copy and paste the sample KML code below into a text editor and save the file with a .kml extension and with UTF-8 encoding, then you will create a KML file. http://earth.images.alaska.edu/geog493/class.html

KML Elements

• Between the KML designation tags are placed one or more elements that relate to various features and functionality that can be created.
• Element names (contained within <>) are case sensitive

If you get done early…..

Use the measuring tool to measure the following:

1. Distance from the center of the Sun Bowl to the Geology Building (in km)
2. Distance from El Paso International Airport to UTEP’s Hilton Garden Inn Hotel using major roads/ I-10 (in miles)
3. Distance from White Sands Missile Range to the Grand Canyon (approximately, in miles)
