Keep in mind…Keep in mind…
• The images are not in real-time. Most images are two to three years old. Overhead images have been obtained from a variety of sources, including declassified satellite data and commercial aerial imagery.
• Most of the earth is low resolution imagery, but some places, such as major metropolitan areas, offer much higher resolution.
Almost all of South Carolina is in high resolution!
Polar OrbitPolar Orbit
• Satellites are in a Polar Orbit
• Images tend to run North-South

7 STEPS TO CREATE A PLACEMARK IN GOOGLE EARTH v. 4
1. Click here to create a new placemark. The New Placemark box opens.
2. This is the new placemark.
4. Name the new placemark.
3. Choose an icon.
5. Add a description for the placemark.
6. Click OK.
7. Finally drag the new placemark to a folder of your choice, or create a new folder. Don’t leave it in temporary places or it will be deleted when you log off.
SearchingSearching
Users may search (Fly to) using the following parameters:
• Address (street and zip code for US)
• Place Name (eg. Paris, France)
• Keyword(s)
• Latitude/Longitude Coordinates
Search results depend on the current view.
KML FilesKML Files
• Keyhole Markup Language
• KML files are XML files and can be directly edited with a text editor.
• KML files can be renamed as XML files and opened with programs such as Excel.
• KML is text only, and cannot contain actual image files. However, it can contain links to images online.
KMZ FilesKMZ Files
• Keyhole Markup Zip file
• KMZ files are KML files that have been compressed into ZIP files.
• KMZ files can contained image files.
• KMZ files cannot be directly edited with a text editor.
• KMZ files can be renamed as ZIP files and decompressed.
Google MapsGoogle Maps
Google Earth files may be shared with others online through Google Maps even if others do not have Google Earth installed. Simply go to Google Maps at http://maps.google.com and enter the URL for your KML or KMZ file into the Search box. Your Placemarks will be loaded into Google Maps. This method does not work well with dynamic data.

• In addition to location and appearance, the current zoom level, bearing, and tilt level can be recorded in a placemark.
• A “snapshot” can be taken of a current view of a placemark to record these items.
• Placemarks can either be clamped to the ground, or can appear above ground at a specified altitude.
