Hi,

I'm trying to draw (in Photoshop) trees from a place where it's possible to see 15 kilometers on one 1920 pixels screen.

The best I did was to make squares of trees, with shadow and Bevel and Emboss (with texture). I also added some noise, but it's far from perfect...

So... I don't see any tutorial precisely on this subject, because most of the maps here come with more details of the ground. If you have some lead, that'd be great :)

(Same thing for cities)

Thanks!

At that res, each pixel is 7.8m across so really its more of a tree like texture than actual tree shapes. You might be better off getting hold of some aerial trees at a higher res than that and resampling them down such that they are approx 7.8m per pixel and then using that as a texture fill into the areas you want to put trees down. Since NASA images are public domain I am sure you could get something from them for terrain and cities at about that scale.

The NZ land info service has a lot of high res photos like that too. They are not public domain but do allow some reproduction usage with acknowledgements. So have a look at these for 25m or 2.5m trees.

Thank you for your answer.

Problem is that I'm not satisfied with tree textures. They're too realistic for what I want to be done.
I saw this : http://www.cartographersguild.com/showthread.php?19680-Laer-Ia-Bor-by-LonewandererD

If someone knows how to do that :)

It looks like a textured brush with a bevel and emboss layer style, if you post twice more, you can send a PM to Lonewanderer and ask him how he did it :)

Ok let's do this !

So, uh, how do you do ? The sun is warm and the rain is not.

I've also created brushes from moss and bathmats... which can be effective depending on your needs. =)
