Imagery Update: Google Earth Using Spot Image Satellite Photos in Europe

[UPDATE 2:30PM ET: Spot Image has released a press release about their multi-year agreement with Google to provide new imagery such as the new data described below.]

Google has updated imagery for Belgium, France, Portugal, and France to use CNES/Spot Image satellite imagery at 2.5 meter resolution imagery instead of the old Terrametrics/NASA 15 meter resolution base imagery. So, in other words the low resolution areas are 6X better resolution. Stefan Geens at OgleEarth got the details from Spot Image:

It covers France, Spain, Portugal and Belgium. It is made of imagery from our SPOT5 satellite : 2.5m in resolution. The images are selected from our existing catalog (most recent and cloudfree). They are then combined to make one single uniform image. To cover France, we need roughly 500 SPOT5 images which are of course taken at various date, sunlight, angles, etc...

Stefan also says some new high resolution Digital Globe strips are in Belgium. I am quickly researching to see if other areas have been updated in high resolution. Please drop a comment here if you find new imagery.

By the way, this is the first Spot Image satellite imagery in GE I've seen. It's interesting to see Google is expanding it's source of imagery data to another commercial satellite provider. A few days ago Digital Globe's newly acquired GlobeXplorer announced it was selling data to Microsoft. And now this happens. Probably just a coincidence, since I'm sure it took more than a few days to implement this imagery.

    Luxemburg, Italy and Switzerland have got some of these spot images, too

    The high resolution strip of Brussels is a few months old.
    At the moment there are no new high-resolution strips of Belgium. Only the low-resolution which is fantastic btw.

    All of Spain and Balearic Islands has been improved in the "base map" it means where no high resolution images were available before. They have not a vey good quality, you can't see things as cars but it is easy to see roads, houses, trees, ...(as far as I tried different places to check but not 100% of Spain, of course).Places in high resolution has still the same image provider (not this new one Spot image) so it has been used to improve paces with no-resolution.

    This new 2.5m SPOT imagery has 6x the linear resolution of the former 15m Landsat-derived data along each of two directions. Each single pixel of 15m imagery is replaced by 36 pixels of 2.5m data. The difference in resolved detail is great, as can easily be seen along the southeastern border of France.

    This is an amazing update for Portugal. :D
    Altough "Spot" imagery has at least one year old, it seems updated because google hasn't been updating google maps for a while. And many changes must be made!
    But i think that if "Spot" didn't take this pictures, no one else would.
    5 stars for GE :)

    Not very good imagery I must say, but I hope we will get more and better before month is over

    Checked areas of Central Portugal that I know well and found the images disappointing in terms of quality, although it is an improvement over previous images

    How often are the the maps updated? When can we expect to see the USA updated?

    Unfortunately, there is no high-res strips of Waterloo, Belgium. Anyone knows where I could find some???

    Ireland photos are very poor. A big disappointment for what is advertised.

    Is there a comprehensive guide anywhere to Google's planned coverage updates? Have struggled to find one with basic web searching. Specifically, I'm interested in York, UK - England's second most visited tourist city and still no hi-res images! Any help much appreciated - I plan to create my own maps for use in the tourism industry.
