How often is "Google Maps" updated? ?

I saw a street view of my grandparent's house and stuff. It wasn't too long ago, I know that, but about a month ago there was a house that was painted brown, and on Google Maps, it is still the original color. So, how often does this update?
How often is "Google Maps" updated? ?
It's updated when Google receives new satellite imagery from their various sources. This can change wildly depending on where the satellites have crossed over recently, and based on how long it takes for Google to stitch all these millions of images together to overlay the street data, especially for areas that you can zoom in pretty far to.





Some places may have a picture as recent as three months, or a few years. I think I read somewhere that Google tries to have all its images at least within four years, though my own city's images are -at least- four years old, so I'm not too sure about that.





In other words, there's just a lot of information for them to retrieve and put together, so it's not updated too often; maybe once every two or three years. And there's almost no real definite way to no how often your particular area is updated, other than just trying to find landmarks that aren't built yet, or other stuff, like the color of your grandparent's house.
Reply:Depends on your location. I live in the Suburbs of San Diego and moved into my constructed home in 2005. Google Maps still doesn't even have my street on the map yet.
Reply:According to Google every 1 - 3 years.
