  1. Beginning KML Looking at Data with Google Earth

  2. Review: XML, HTML • Data • Descriptive data vs. List of data • XML • Tags, Attributes • Opening/Closing tags • HTML • XML Tags for the web

  3. Look at Websites • Let’s look at your websites • Any questions? • Let’s look at some sites online! • Google Chrome -> Inspect Element

  4. Before KML • Let’s Check Google Earth! • Is it on the computers? • If not, let’s download it! • Google Earth can be put into a web site!

  5. KML Basics • Points – Also called Placemarks • Paths • A list of points

  6. Creating a KML Point <?xml version="1.0" encoding="UTF-8"?> <kmlxmlns="http://www.opengis.net/kml/2.2"> <Placemark> <name>My SNU Office</name> <description>Where I code</description> <Point> <coordinates>126.949273,37.458426</coordinates> </Point> </Placemark> </kml>

  15. Create Your own Placemark! • Find a Longitude and Latitude using Google Earth

  16. Creating a KML Path • We will need to create a list of: • Longitude • Latitude • Elevation • First an Example

  17. Path Example:

  18. Looking at Code • We will make our own Path • Use Google Earth to create a list of points • Then put them into a KML file, and load it into Google Earth!

  20. Next Week • I want to look at embedding Google Earth with KML files on a website. • What would you like to do? • Can your phone record your GPS location and path? • We can do cool stuff with this!
