Head on over to maps.google.com and check out their new terrain layer. Rather nicely done!

Nicely done indeed. Google goes in closer than Virtual Earth, and has a crisper imagery, at least in the areas I checked....

I am really happy with these new terrain tiles. I have set them as default on:

and

I looked around some more. It's like the air photography -- sometimes Google is better, and sometimes Virtual Earth.

Thanks I will find that information while I'm using Google for reference material on my project.

"There is much beauty that we fail to see through our own eyes teeming with life forms that give us that perception of our reality.  Leaves on the trees blowing gently in the wind, or scarily, the waves pounding through high surf, or lightly on a warm summer’s day; that opportunity to sit or swim in the water on a white beach.   That comfort to shout, “The universal conscious do you hear me?  I am alive, guide me dear logos towards the path of rightnesses.”  Earned what has been kept, no longer to be absorbed into a life filled with cold damn winds and  that stubborn fog clouding  my vision with nothing but darkness."

Yes, the terrain is certainly aesthetic, but I find it difficult to follow a road through an area with lots of relief, because the roads are rendered in a gray color that's not much different than the gray shadows. I wonder why they didn't just use their familiar orange-yellow-white scheme for rendering the different road classes. But then, it's a new product, so perhaps refinements will be made.

I find their relief very interesting. It seems they used different techniques at different scales (analytic hillshading, slopeshading, mixed illumination, etc.) I also find their use of tint intriguing. There seems to be several shades of green for parks, semi-urban area, forested areas, etc.

I'm wondering what dataset(s) they used...

It's clearly a work-in-progress. I sampled two areas in Canada with which I'm familiar -- Nelson BC and Toronto -- and compared with Virtual Earth. In BC, it looks like both are using provincial data (TRIM), but Google seems to have blended vertical with oblique illumination. In Toronto, Google has a kind of knobbly surface that seems to say "wait, we're working on it", where VE has a very generalized obliquely-illuminated relief image, perhaps from the Federal 250K data. Just a guess.

The terrain all over Canada looks really bad. Not to mention the lakes and rivers. I was going to do one map of Niagara Falls and gave up after trying to get files of Canadian side for two months. Glad to be in US.
