Using Google Earth to Explore Estuaries
Introduction
Google Earth is a virtual globe web site that lets people fly around Earth, zooming in for details or zooming out for a broad perspective. Google Earth uses satellite imagery, aerial photography and a 3D globe, putting the world’s geographic information at your fingertips. With Google Earth, you can:
* Fly to any location. Just type in an address, press Search, and you will zoom right in.
* Search different types of terrain and study geologic and estuary features from any altitude.
* Tilt and rotate the view to see 3D terrain.
* Save your searches and image data for future use.
Google Earth is a powerful tool for exploring your world. In your study of estuaries, it can be used to reveal the relationships among landforms, water features, towns, cities, and the habitats of the animals and plants that live in estuaries.
Sharing Places Information - Google Earth User Guide
-
- Accessibility - If your place data is stored on a network or the Web, you can access it from any computer anywhere, provided the location is either publicly available or you have log in access.
- Ease in Distribution - You can develop an extensive presentation folder for Google Earth software and make that presentation available to everyone who has access to your network storage location or web server. This is more convenient than sending the data via email when you want to make it persistently available to a large number of people.
- Automatic Updates/Network Link Access - Any new information or changes you make to network-based KMZ information is automatically available to all users who access the KML data via a network link.
- Backup - If for some reason the data on your local computer is corrupt or lost, you can open any of the KMZ files that you have saved to a network location, and if so desired, save it as a local file again.

Sharing Data Over a Network
In addition to saving placemarks or folders to your local computer, you can also save place data to a web server or network server. Other Google Earth users who have access to the server can then use the data. As with other documents, you can create links or references to KMZ files for easy access. Storing a placemark file on the network or on a web server offers the following advantages:
- Accessibility - If your place data is stored on a network or the Web, you can access it from any computer anywhere, provided the location is either publicly available or you have log in access.
