Google Earth Errors

I've been wondering why some of my GPS tracks were not overlaying on Google Earth accurately.<br><br>
Today I had a track that ran down Portrush Rd (South Australia) and found out the reason.<br><br>

You shouldn't need an account to access it. Although I could be wrong.

I have seen the photo mismatches near here in Ballarat, they except ours over here of more that there is a duplicate in a small area rather than missing pieces altogether....

Consider there is a manual part to this process....

That's nothing, check out the 500m error down at Normanville, SA.
S35 27, E138 17.
I emailed Google about this when they plonked the hires aerial photo totally out of position. They got back to me and said they would correct it on the next update. That was back in May, the update was in June and they never did fix it. Still stuffed.
The other thing they have wrong through most of SA is the DTED elevation data is out of position by about 100m+. So you have rivers along valley walls and ridge roads not on ridges. And it's not just because it's lo-res elevation data, it's consistently out in the same direction. WGS84 anyone?

Of course to fix it they have to rebuild their entire elevation model in this area so that's not going to happen in a hurry.
