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:

KML vs KMZ

•  KMZ is a zipped version of KML.

•  If you author KML that uses images, icons, or data sets that are stored on your local drive, in order to share them with other users they must be combined into a KMZ archive.

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:

<?xml version="1.0" encoding="UTF-8"?> <kml xmlns="http://earth.google.com/kml/2.2">

•  and end by with a closing kml tag: </kml>

•  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

KML Balloon Descriptions

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)
