Actually the Rowan terrain ain't all that great these days. I found some early BoBI pics the other day. Goodness me.
They worked from OS maps, not modern photographs.
One thing I would comment is that the current set of textures all came from Western Kent/Eastern Suss ex. I now forget who sampled them originally (Stiz?). In fact the textures have considerably *less* woodland than they had in the original sampled photos which were far more wooded (also compare with 2.08 textures which were much fussier).
Now if you take a look at Cowbeach, Suss ex, this will be very familiar
(especially as you get down to 2000ft scale and below). A lot of stray woodland, btw, not just as hedgerows.
If you look at the section from Hailsham to Ninfield and compare against the RAF map, the real world is considerably more detailed. There is just a ton of field, tree and terrain detail that isn't in the map.

Equally, look at Uckfield in Suss ex (close to where I grew up)http://maps.google.co.uk/maps?hl=en&q=u ... 1&ct=title
as you look at the field area to the East, you see a level of complexity that is just not represented at all in the maps.
The real pic has a ton of trees that aren't in the map (note than the scales are not the same, it was tough to match them).
This one is much lower level than the map but you can recognise the shaped wood.
The ingame shot isn't the same as the real thing, of course, but in these areas it isn't bad. If anything things are more open in-game than in R/L. And my point is that this area is fairly typical of the area between North and South Downs.
Overall, it's just a choice really. If you sample more of the coastal areas it would look unreal inland.. And as the textures aren't really that well allocated between coastal fields and inland fields you have to play games. Of course they can be reallocated, but it does take a lot of time.
If you want to make a new set, then that's just super. I'm sure it'll be a great addition.
Given the incessant rise of texture memory on cards I am already thinking that the next set should all be 2048x2048 which means we can increase the terrain resolution further still.
