Question: How do I look at an aerial view of my house from this site?

Answer: At http://www.terrafly.com, there should be a yellow box in the center of the page where you may fill in the street address, city, state or zip code. This is a java applet that is automatically downloaded to your browser. If you see a gray box, you may not have java enabled on your browser. You may enable java by setting these options on your browser. You can see Aerial Photography over most areas of the United States by filling in the address, or the city and state, or the zip code of the area you would like to see, and clicking the "fly" button. We also have sparse data over other areas of the world. You can see those by clicking on "Recommended Starting Points.” If you are using a Mac or WebTV you might encounter problems in using TerraFly. We are constantly working to solve these problems. However, currently TerraFly works best on PCs running Windows operating system. For a complete Tutorial on using the website please visit TerraFly Help page.

Question: Do I need to register or pay anything to use TerraFly?

Answer: Currently you don’t need to register or pay to “fly” over Aerial Photography. If you like the image that you are flying over and want to purchase it, then there is a nominal fee depending upon the size of the area and the resolution of the image.

Question: I did exactly as you have shown to enable java. I still cannot access Terrafly. What else can I do?

Answer: If Terrafly still doesn’t work on your machine or you don’t see both the “control frame” and fly-frame windows, your Java plug-in might need to be updated. You can download an updated version of Java from the following website: http://www.sun.com/2002-0214/feature/. These instructions are to help you get the best experience of Terrafly.
