Many areas of the world are still very fuzzy in Google Earth - including
Kent, SE England. Hardly the Third World, as the London to Paris High Speed
Train runs through it.
When are Google going to widen their close-up coverage?
By the way, what's the best newsgroup for imaging questions?
Thanks,
Rob |

Rob... the close-up coverage must exist before Google can make use
of the data. Aerial photography of the resolution you desire is not
done, but by a few countries on this planet. |

What about the competition? http://maps.live.com/
As a quick test, it's easy to see that Ashford, Kent is much more detailed. You
can even see the London to Paris High Speed rails, but sadly not the Train. |

Of course Google also participates in censoring, check out a close in
view in Google Earth of MIT Lincoln Labs.
42°27'29.83"N
71°16'39.66"W
Clearly the surrounding area is very high resolution, but the area
over the lab, runways and surrounding area are pixilated close in, in
a very deliberate manner.
There are also areas in China with the same effect.
This leads me to believe they don't always put up what they have or
have access to and can be influenced by outside sources. |

Don't think it is Gogle who does it. There are licensing restrictions
on data with 1 M ground resolution or better. For some parts of the
world, the data is just not readily available. Take a good look at
various parts of Israel on Google Earth. Ben-Gurion Airport is very
low resolution, while most of the coast near Tel Aviv is high
resolution. By contrast, the ground resolution at Amman Airport is
very high, not difficult to guess what aircraft are on the tarmac. No
license restrictions on Jordanian imagery... Ground resolution at
Cairo is also very good, check out the airport.
The Russians upset the apple cart a few years back when the turned
over 1m ground resolution imagery of Area 51 to Aviation Week and
Space Technology, who published it. |

I imagine the view is degraded because it's Hanscom Air Force Base not
because MIT Lincoln Labs happens to be one of the facilities there. |

Also take a peak at www.flashearth.com for some more and quite a good

It certainly seems to be "potluck" whether an area you are interested
in is available in high resolution with Google. The best resolution
images available to the public in Spain appear to be SIGPAC (Sistema
de Información Geográfica de Parcelas Agrícolas), which is the system
for identification of agricultural holdings. There you can measure
areas of fields, count olive trees, etc.; used for determination of
grants by the local ministry of agriculture. Not too sure whether
these types of images are available right across the EU, given that
they are handing out money from European taxpayers. |

As I understand it, Google do not do surveying nor do they commission
surveys. They use what they can find. In the U.S. the state of New Jersey
is depicted at high resolution on Google Earth because the state government
paid for a complete aerial survey, but many parts of the U.S. (and much of
the world) is at low resolution. Microsoft Virtual Earth seems to have
better (and more uniform) resolution in some places I have looked, but I
have other troubles with it.
Quote: By the way, what's the best newsgroup for imaging questions?
There is a Yahoo Google Earth Group, and may be other imaging groups.
Good Luck

For places like Vietnam, the Google Maps is of much higher resolution. |

Yes. In fact, after some initial searching I haven't found an area
that *doesn't* show high resolution with http://maps.live.com/
Now, if it only had Google's facility to automatically move through a
route or path, plus tilt, etc...
GE's mapping is baffling to me, with some areas high res and adjacent
ones low - even within the same apparent 'date zone' or whatever it's
called. For example my home is high res (although 9 or 10 years old),
but a few minutes walk away it's low.
And when viewed from 30-50 miles high, you can see what a quiltwork of
different photos the UK is made up from. But only from Google's
database...

Resolution has also increased.
Google Earth - Layers - Digital Globe Coverage
If you zoom to the right level, the date appears.
In some areas, the overlapping data makes it difficult, if not impossible,
to tell, but out here, there are very clearly a couple of layers.
You can elect to show only one year at a time on the overlay to get better
clarity.
In some areas, there is an "i", that you can click for more information,
and the background photograph itself.
<http://archive.digitalglobe.com/archive/showBrowse.php?catID=1010010004AABD04>
from 2005-11-23 seems appropriate for for my home, and that jives with what
I can see in the photo, definitely after July 2005 and before Jan 2006, due
to changes on my property.

Maps Live may be good in some areas but it is deficient where I live.
There isn't even any photo view for the City of Lethbridge, Alberta.
And it makes the same error as every other mapping program I have found
on line - including GE - when asked to locate my house address.

Resolution has also increased.
We live in a remote area of NW Washington State near the Canadian
