Nice, but when I looked at my back yard on google earth, there are tress pictures there that I cut down in 2001! I wonder how often they update their pictures.

Google Earth is there to prove that there was trees there and you cut them down :(

Good grief, people! Every time I read comments about Google Earth, everybody's always complaining that the imagery is so out-of-date! "Do they update it daily? How many times a day?" I kid you not, I actually read that complaint on another site.

Why don't the complainers stop to think that our planet has nearly 200 MILLION square miles of surface? Any idea how expensive it would be to keep that much imagery "up to date"? Do you think there are an infinte number of spy planes and satellites constantly criss-crossing the globe, to provide this information? Would you want there to be?!

I am amazed and thankful that the imagery exists AT ALL, even if it does happen to show a picture of my house from a couple years ago, and the nearby mountains from a several years before that. And that it is available to us for free, when it cost untold millions of dollars to compile, stitch together and link with the actual topography... that is just amazing.

You ask "Do you think there are an infinte number of spy planes and satellites constantly criss-crossing the globe, to provide this information? Would you want there to be?! "

Well, yes unfortunately there are. Most of them belong to the American military and much of the data they collect is classified. The GPS system runs on this network. The American military make this data available to certain other countries but reserve the right to downgrade the quality if they need to, for example when invading Iraq.

For this reason Europe has started it's own satellite project, Galileo, details of which can be found at www.eu.int/comm/dgs/energy_transport/ galileo/sa/index_en.htm.

Whether all these things are a good idea or not is beyond the scope of this post, but rest assured Google Earth is just the tip of the iceberg as far as applications of this technology goes. Applied satellite data is going to have an enormous impact on all our lives over the next few years.

Take a pill and calm down. I simply wondered how often the pictures get updated. 'wondering' and complaining are not the same.

Your post, however, sounded pretty whiney.

Sorry, I didn't mean to sound like such a whiner. And I really didn't mean to direct my whining exclusively at you, either. I apologize. I guess I was just venting pent-up frustration after reading several comments on other boards where others were, in fact, complaining.

I am a happy and satisfied user of Google Earth (and have been on Windows for some time), and in my zeal to defend what I see as a great service, I mistakenly linked your comment with other complaints I had read. (Like somebody wanting to check whether their wife was at home while they were at work.) Again, I realize your intent was not to complain, and I apologize for grouping you in with that crowd.
