I'm quessing, but I think, he just wants to know how they look like, how they are built up. With that in mind, it doesn't matter if it is a grass texture or a sand texture. They should look similar (I guess).
Concerning the WorldMap Map... Yes, that bothered me too, that every thing had its name. I mean, for the main places, such as Nibel, North Corel, you could have the names in there, but isn't really necessary, in my book.
