Creating a New Placemark

Tip - Follow a tutorial on this subject: Marking Locations
Follow these instructions to add a new placemark to any spot in the viewer.
  1. Position the 3D viewer to contain the spot you want to placemark. Consider zooming into the best viewing level for the desired location. Choose any one of the following methods:
    • Select Placemark from the Add Menu.
    • Click the Placemark icon on the toolbar menu at the the top of the screen
      Pushpin icon
      Pushpin icon
The New Placemark dialog box appears and a New Placemark icon is centered in the viewer inside a flashing yellow square. Position the placemark. To do this, position the cursor on the placemark until the cursor changes to a pointing finger and drag it to the desired location. The cursor changes to a finger pointing icon to indicate that you can move the placemark.

You can also lock the placemark position or set advanced coordinates for its position. Set the following properties for the new placemark:
    • Name for the placemark
    • Description, including HTML text (see Writing Descriptions)
    • Style, Color - Choose a color, scale (size) and opacity for the placemark icon
    • View - Choose a position for the placemark. For explanation of terms in this tab, mouse over each field. Click Snapshot current view to apply the current view (altitude and camera angle) to this placemark.
    • Altitude - Choose the height of the placemark as it appears over terrain with a numeric value or the slider. Choose Extend to ground to show the placemark attached to a line anchored to the ground.
    • (Icon) - Click the icon for the placemark (top right corner of the dialog box) to choose an alternate icon.
  1. Click OK to apply the information you entered in the placemark dialog box.
Your placemark appears in the 3D viewer and as an entry in the selected folder. Once you save this placemark, you can always change its position and properties. See Editing Places and Folders for more information.




Writing Descriptions

The description field for places and folder can contain a lengthy amount of text, sufficient for detailed descriptions. When you click on a placemark icon in the 3D viewer, the description for that place appears in the information balloon that pops up. A scroll bar appears when the description is too long to fit in the entire balloon.

Keep in mind the following points about text in the Description field:
  • Valid web URLs are automatically converted to HTML and can be clicked on from the info balloon to produce the related web page in the web window.
  • Many HTML tags are respected, such as font, style, and table tags. If you are familiar with HTML, you can be quite creative in how your descriptions are formatted! All HTML tags should be properly closed.
  • You can include images in your description using the IMG HTML tag to refer to either:
When you email that placemark to another person, local images are included.
Note - While theoretically the amount of text that you can enter into a description is unlimited, an extremely lengthy description can negatively impact the performance of Google Earth.
