I am intrigued as to why whereis.com.au uses more up-to-date sateilite data than GoogleEarth. I also notice that the data with whereis satelite data is of a higher resolution than GoogleEarth.
Does anyone know why this is?
BTW, the GoogleEarth data of our house is about 2 3/4 years old whereas the whereis data is about 2 years old. How do I know this?
Well we built a new house. GoogleEarth shows the old house partly demolished (this was done in April 2005) and whereis shows the new house with the piles of bricks sitting on the property (this was taken between Dec 2005 & Jan 2006).

Wheris pic was taken within the last 12 months. There is a block of flats being built down the road. where as google earths must have been taken over 3 years ago before I moved into this place as I can see my rusting 4runner in the pic in whereis but it is not in google

Maybe that Google Earth comes out of USA and whereis is the Aussie update?

May you are right. However, I did a comparison of the satelite view of our house which is 25kms east of
Melbourne and the
Nullarbor roadhouse.
I found that the whereis data is of a much higher resolution and more up to date for our house, whereas GoogleEarth gave a far superior satelite view of the
Nullarbor roadhouse. In fact, asked whereis to find the nullarbor and it couldn't find it. GoogleEarth took me straight to it.
So in summary, it appears whereis is better for the major
population areas, but GoogleEarth gives better outback coverage.

I just had a quick look at the
Gold Coast using Whereis and it is high res unlike
Toowoomba which isn't.
I found a join in the images around Broadbeach where some of the buildings (like Q1) are taken from a north perspective and the buildings next door are from a south perspective. A bit eerie to look at but it shows the time of day is similar but the angle is quite different.
I suspect that if you really look you would find many small differences in the actual date of many images taken even side by side.
I also had a look at google maps. It's images of the same area is much earlier in the day and mostly from a slightly southerly perspective (which is better for orientation). It seems a lot more seamless though.
Googlemaps and GoogleEarth of my house near
Toowoomba are different times but reasonably close and the local gov't mapping is different again but newer.
Too many choices :)

Google earth is free to anyone except commercial.
The images Whereis uses would be hi def commercial data that costs them 10's of thousands of dollars to have the right to use and on sell.
Whereis makes there money out of selling there software to people like Garmin, Tomtom etc. etc. and in the end we are the ones who pay for it when we buy a GPS.....this may help keep there web site free as they don't have to recoupe there money from a web site and can afford better data.
Remember Whereis is owned by your friend and
mine TELSTRA so the question is how long will there web site be free.

Hi there,
As a member of the Whereis.com team, I can definitely assure you we're not planning on charging our users.
Also, not sure if you've heard about our new beta site -
http://beta.whereis.com - we've added labels (i.e. hybrid) to our satellite and aerial imagery. Oh, and we've just added clearer imagery for
Cairns and north up the coast. And, our
Hobart imagery is pretty nice too, and fairly recent.
Cheers,
Danielle

G'day there Danielle. Great to here from you. Great map programme you're developing.
I had a look at the beta version that you suggested.
Unfortunately the two spots that I looked at are way behind Google, but that is no guide as to the overall quality of either product.
Wish you the best with the project.
Regards,
Laurie.

Whereis may have done their satellite data after Google but that only means Google will be updating their data before Whereis next time.
