Does anyone know how long images are "aged" prior to being made available on
Google Earth? My guess, based on local construction projects, is about 4 years. Wayne http://www.soaridaho.com/ "Ramy" wrote in message ups.com... While Google earth has amazing resolution, it will not show day to day changes, and the images are usually over 1 year old... Ramy Wayne Paul wrote: "Oscar Goudriaan" wrote in message ... Why dont you try Google Earth. Depending on what area you need, the resolution is amazing. Go to www.google.com , search for google earth, download and install the file. The Google Earth URL is http://earth.google.com/ Wayne HP-14 "6F" http://www.soaridaho.com/ |

Using the same criteria with Google Maps for the Richland, Wa, area, it's less than two years, maybe even one. But, maybe the update cycle is 4 years, even if it's a relatively new image when it is updated. I still think it's amazing I can see which way my motorhome is pointing (can't be sure about the glider trailer, though). -- Eric Greenwell - Washington State, USA * Change "netto" to "net" to email me directly * "Transponders in Sailplanes" http://tinyurl.com/y739x4 * "A Guide to Self-launching Sailplane Operation" at www.motorglider.org |

Looking at it more carefully, I realize it's the zoomed in (8 highest magnification levels) images that are the newest. As I zoom out, the image changes to an older one from (I'm guessing) NASA satellites. -- Eric Greenwell - Washington State, USA * Change "netto" to "net" to email me directly * "Transponders in Sailplanes" http://tinyurl.com/y739x4 * "A Guide to Self-launching Sailplane Operation" at www.motorglider.org |

I now see a burned area near our house that occurred July 4, 2006, so the image is less than 6 months old! -- Eric Greenwell - Washington State, USA * Change "netto" to "net" to email me directly * "Transponders in Sailplanes" http://tinyurl.com/y739x4 * "A Guide to Self-launching Sailplane Operation" at www.motorglider.org |

I believe they use images that are in the public domain, or similar. So it probably depends on the benevolence of the original owner... I have no idea how this works with government entities, but perhaps one has to wait until they 'get around" to putting them somewhere freely available? All just guessing, so YMMV -Tom |

They use a mix of public and commercial imagery sources. Jeremy |
