How accurate it is? I mean... If i do a search tonite (It's 12:48 am CT, Wed. July 26 2006). The pictures will be from which date?
FYI i am using their new (Beta) version.
Thanks for any info...
Cheers

Usually a few years old. There's a data layer you can turn on that tells you when it was taken, although it can be hard to figure out. Most are relatively up to date, don't expect anything extraordinary.

They recently updated the imagery. Looking at Google Earth now I can spot the concrete that was poured last spring. The pics appear to be taken in the fall/winter time judging by the color of the brush and trees, which would make them less than a year old.

All the locations around the world have all been taken at different time. Zoom out a bit, and you will see the "blockiness" this creates. Just because the area you are looking at is up to date doesn't mean everything is.

They update the images in bunches, usually updating a few places at a time, while at the same time introducing more areas to high-res coverage.

Of course not all pics are that new, but then again, if GE was to have the most up-to-date pics of the entire world, it sure as hell would not be free.

Actually, no, not really, I have heard people say the will get GE to see how a construction site in their neighborhood develops day by day! Admittedly, that's an extreme example, but still.

It's at least a year old in some areas. If you zoom to YQT, you can still see the Global Peace Ambassador's 747SP sitting there in the summer sun, and it was ferried to TIJ last December.

Is there a feature in the free edition were I can enter an EXEACT altitude?? Suppose I dont want to see an EYE ALT. of 25022, but instead of I want to see it as 25000 or 25500...Is there a way to do that???

What difference is 22ft (0.08%) at 25,000 ft going to make? The resolution is not nearly good enough to see any difference from that height. The absolute BEST resolution they offer in some Metro areas is one foot and that's certainly less than a single pixel from that distance.

I would not care if the images were 5 or even 10 years old if the resolution was better for many of the places I want to look at.

Take Bristol UK, Filton is just great, 8 to 10 miles away and Thornbury is near invisible. In Australia, I can barely see the street where I live, but in Balmain in Sydney, I can pick out details of individual houses, same in Randwick. Hampstead NC has the same crap images I do here. I gather it is related to whether a third party has paid for high res imagery. Away from those areas, GE is crap. Sorry, I will rephrase that, it is not of much use.

For many international areas, they are going piece by piece, trying to fill in the high res areas. Many of the less densely populated places in the US are still low res. For example, most of the Caribbean islands and a bunch of the South American cities just became high res. They are also constantly updating much of the already high-res areas. Have patience.

Thankfully, New Jersey is one of the few US states that is 100% high res.  Wink

How well does Google Earth run on your computers? Since I installed it I get the impression it is slowing my machine down due to updating and whatever else it does. Maybe it's just me though.

Thanks for the comment, Hampstead NC is one place I looked at, awful, just like home!! The centre of Newcastle UK is great, but go down SW and in the Village of Burnopfield, it suddenly goes from wow to yuk!

I have some "issues" but mainly the DX GL stuff which is because I have a lousy old video card - I think. Something is killing my machine of late, possibly the Spyware detector, Registry mechanic has helped. I begin to think it might be time for a reload to get rid of all the rubbish, but the thought gives me a fit of the horrors. I will keep an eye open for signs of GE being a culprit. It is very difficult to attribute blame due to the huge numbers of interactions.

Just recently places like LHR and AMS got upgraded to the new high-res images. I assume they will try to get most of the metropolitan areas covered before they do too much of the countryside. Who knows, though.

Some images are just brilliant. I found my old college and I still dont entirely understand the extraordinary relief on the images. Nearly as good as the first time I saw it and the chapel was covered in newly fallen snow.

What I do find odd is that the crappy areas must have resolutions worse than 50 m, whereas the good areas are down to about 20 cm. I can see the front steps on my parent's old house in a high res area, but I cannot even see the street I live in! And the same goes for a friend in Hampstead NC, so it is not just a non US thing. And the difference seems to be about two orders of magnitude.

Remember, also, that a lot of the really high detail areas are aerial photography, while the crappy stuff is satellite imagery.

The part that I can find most impressive, though, is that I can see my red jeep parked in my driveway, and my grill sitting on my patio in the back. Pretty crazy.

You all seem to forget that Google Earth is free, and you're complaining about a free product not being super perfect. Do you have any idea how expensive it is to purchase all that imagery? If you were Google, wouldn't you start on the areas with high population and THEN move on to the rest? Stop complaining, you have absolutely no right to do so. Or better, rent yourself a C172 and shoot those missing photos yourself.

Well, I did not know that some were aerial photographs, that certainly explains the relief effects on some of them. I could find the windows of the room I stayed in for a particular building. I dont have a red jeep, but even if I had, for my place, you cannot even see the road let alone the drive or the house.

And no, Birdwatching, I was not really complaining but when the res goes just where you want it, it is irritating - free or not. I was trying to whistle up the Kirkuk structure which is one of those things you can see from orbit using the unaided eye, and on Google, it is just a mess. The Ghawar oilfield is even more of a mystery. The distant view shows stacks of lines that usually mean high res. With a current in situ value of about 5 trillion dollars I would expect it has been fairly well surveyed. When you zoom in, nothing. I wonder if that is a deliberate safety precaution against you know who?

Thank you for that. Fascinating. Looks as if they are giving up censoring. So I am not censored, just a crappy image! I am not sure if that makes me feel better or not. From the few places I have explored, I just wonder if the list is exhaustive. The Ghawar oilfield has to have been surveyed to the list grain of sand, but it just disappears as you get to the field size - it is about 80 km long N-S!

We have had a couple of citizens put in the slammer for having incriminating photographs. Using GE would seem to have distinct slammer potential!
