I’m specifically curious about the satellite images, but there’s a valid question re. street addresses too.
Near my apartmnet a giant tollway is going up, and actually almost complete. But if I check it on Google Maps I still see the tranquil, undisturbed land of 3+ years ago, before construction began. The blast from the past is cool and all, but at some point the picture will be completely out of date and I’ll be interested to see what it looks like now.
I know Google uses different services to provide images, but how updated are these generally? Can we assume that a given spot will be re-photographed automatically after a couple years?
We moved last August into a new subdivision. The streets have been laid out in this tract since fall of 2004, and it’s only within the last few months that they show on Google Maps. The satellite still shows undisturbed land, but overlays the streets over that.
The apartment complex where I live was built 2 years ago. Not only does the Google Earth photo show a plot of undeveloped land, but the street mapping search engine has no listing for our address. :mad:
I think it depends on how often new photos are taken. These are taken by a variety of 3rd party enterprises (govt & private), and licensed to Google Earth.
If there are no recent updates, google earth isn’t updated.
I’m just glad they finally got something decent for coverage of NH. Now if I could get just a little closer to the ground in their imaging, similar to that of MA, I’d be happier. But I use the GRANIT MAPPER for good topo/imagery for my area anyway.
The Google Maps satellite photo of Hockenheim, Germany still shows the nearby Hockenheimring racing circuit in it’s pre-2002 configuration, so it’s been at least four years there.
The track’s current and former profiles - significantly different - are shown on the wikipedia page.
If it uses the same maps as Google Earth (almost certainly), you can check who took the picture by checking the… DG option (I think… don’t have it installed here), which will show you the original photo with photo date, owner, meteorological data, etc.
Not an answer, but that might give you some information.
Lemme check this other PC… looks like they’ve changed it to “Digital Globe Coverage” in the “Layers” section.
Make sure it’s checked, then zoom in someplace and click on the (for me, anyways) blue ‘i’ icon. It shows date, cloud cover and quality, and if you select ‘Preview’ seems to show the original source image.
Gotcha. However, it says the image of the construction site I linked to is from March 2003 - and given that I watched rugby being played in that stadium the summer before, this doesn’t quite fit!
The Google satellite imagery for downtown Chicago dates from around 2002: many of the footpaths near the museum campus have been re-routed since then, and Millenium Park is still a construction site.
Oxford’s still a blur, though the land south-east of the city is crystal clear. That and my missing islands mean that I’m very poorly represented on Google Earth. Anyone want to join me in a class action suit? I want to claim back what I paid for the software, plus another 50% for mental distress.
