Section 1: Creating Points
Overview
The ability to mark a point is a fundamental concept for all maps and globes. In KML this is done using . The default marker is a yellow push-pin, where the tip of which marks the location. In KML terminology it is actually a parent element with a child.
Tutorial
1. Searching for Locations
In Google Earth, search online Google Earth (KML) files for the Giant Pink Rabbit. To do this, simply type “ Giant Pink Rabbit ” in the search box. Note the results of your search will appear in the search bar, where Google's locations are shown with red markers, and the user community placemarks are shown by blue markers.
Question 1: In which country is the Giant Pink Rabbit located?

Note that the latitude and longitude locations of your mouse are tracked in the bottom left corner of the Google Earth viewing window. If these display as Degrees-minutes-seconds format, go Tools Options 3D View tab , then click on the Decimal Degrees button. (Note, on a Mac, you need to go to the Google Earth Menu Preferences 3D View tab. )
Question 2: Provide approximate latitude and longitude coordinates (in decimal degrees) of this location:
2. Saving Searches to My places - Position yourself over Sydney, Australia. Use the search tool to do this. - Search for the location of Aquatic Ping Pong and zoom-in. - Create a Placemark for this location. Rename it Destination Ping Pong. To do this, go to Add Placemark , or click on the Add Placemark icon. - Note that your new placemark symbol now shows in the Places window. If it doesn’t, right click and select Save to My Places. - Clear (select and right-click delete) your search items from the Search

4. Description Balloons - Open your placemark properties again and write in the description box:
Hello Earth, I'm playing ping pong!
- Select OK and check the balloon by clicking on your placemark icon.
- Re-open the properties and add the following text (as a second line of the description) that will provide a web link.
http://en.wikipedia.org/wiki/Ping_Pong
- The enter link here command represents a web link.
- Re-open the balloon and check that the webpage link works.
- Experiment with changing the format of text displayed in your placemark balloon. Open your placemark properties and make the text italicized and red. To do this, add a and a on the front and back ends of your text to make it italicized:
Hello Earth, I’m playing ping pong
Then add the following layer to apply color:
your text here
The color code for red is ff0000. Other color codes can be found at http://html-color-codes.com. Use pg. 11 of the Digital Explorer handout for more documentation about formatting placemark text.
- Now Save your placemark to your Lab11 folder on \geobase (you’ll need to create this folder first). Right-click the placemark and select Save Place As. Give your placemark the name YourName_pingpong.kml. Select the Format as Kml. Note that a .kmz file is simply a zipped version of a .kml file.

Exercise 1.
Create a placemark located at the UTEP campus with a description balloon that contains the following:
- Name the placemark UTEP
- UTEP internet address: http://utep.edu
- Insert text that contains the address of your home Department, ie: University of Texas at El Paso, Department of Geological Sciences, El Paso, Texas 79968.
- Insert an image of UTEP (see below)
- Insert the UTEP logo (see below)
- Save your file as YourName_UTEP.kml and drop a copy in the DropBox
To insert an image of UTEP and the UTEP logo, use pg 12-13 of the Digital Explorer handout for help. You will first need to find the images you want to use, and a good place to start is at http://images.google.com. Type in “UTEP” or “UTEP logo” in the Search Images box to look for images. Once you find an image you like, click on the link, then click on See full size image , then copy the full web address of the image. (Note, on a Mac, you can right-click on the image and select Copy Image Address). Then open the placemark properties, and add an “image tag” to the description. This is just additional text that gives the web address of the image, in the following format:
< img src=”http://your.image.address.jpg”>
- Save your placemark to your Lab11 folder on \geobase. Give your placemark the name YourName_UTEP.kml.
- To scale the image down to size, you can append the text object width=”100” height=”100” inside your
![]()
command. The numbers are in pixel dimensions, so you can vary them as large or as small as you like. See p. 39 of the Digital Explorer for more help.
< img src=”http://your.image.address.jpg” object width=”100” height=”100”>
Exercise 2.
Create a placemark at Redoubt volcano with a description balloon that contains the following YouTube video of the recent eruption from the Associate Press: http://www.youtube.com/watch?v=0CN-EGuCBUg. Use pp 39-42 of the Digital Explorer handout for help with this. Simply copy and paste the Embeded text from YouTube into your description balloon text.
