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.

Yes very old. I've been browsing through places in Sydney and roads aren't there which are were built 2 years

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.

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.

You'd be also suprised at how many people think Google Earth is 100% satalite..!! Much of it is not. It's done with photo survey aircraft.

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! Just before you get to the old home of the great Colin Milburn - not Jackie, Colin the cricketer.

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.
