this is exactly how id make a moon texture Mr LBPB (i only used photoshop for this tutorial. i dont expect everyone to have access to l3dt filter forge etc... also i have rushed this very much so i appologise however i have outlined the kind of techniques i would use)
if it was my map to be entirely honest i wouldnt use tiles for a moonish texture.
first step to ANY texture is to look at some base images.. these could be of canadian forests, sahara desert, the alps or indeed any set of images that are linked to what your going to produce
here are some base images (found by google search for "moon" and in adv options telling it i only want large images)

my mini tutorial
try to pick a base colour it may be grey but i would put in a small hint of yellow or something
(ok try to follow layer 1 is going to be at the bottom, layer 2 above it, layer 3 above layer 2 etc...)
layer 1:
ok first fill this layer with your base colour (choosing your base colour is the hard part) and thats it...
ive chosen
hue - 50
sat - 40
bri - 75
layer 2
ok what is the moon famous for?
tis right all those mini craters. (is it craters or crators? =/ ) anyway, this is a littile bit of hard work. but what we want is a series of white dots all over this image of varying sizes, i have a brush tool to do this, i dont have time to do it by hand (1 crater at a time) so mine looks a little sucky. but it gives an idea.
ok then go into blending options for that layer. (in PS right click on the layer and select it) and then fiddle around with the emboss settings. finally just set layer 2 to multiply blend mode.
layer 3
hills dust etc.
actually i say its layer 3 but i lie. make a copy of your last layer (layer 2) and disable all the emboss settings, set it to normal blend mode
use magic wand select tool to select all the non-white part
fill it with 50%grey
and add monochromatic 400% gaussian noise
ok now in order:
ctrl + d (deselect anything that is selected)
ctrl + a (select everything)
ctrl + c (make a copy of everything)
go into channels tab (usually near layers tab)
add a new chanel
select this channel
ctrl + v paste into this channel
ctrl + d
the created channel should be called alpha channel
now click on the layer 3 bar and it should be all good
now press ctrl + a
then press delete
and fill the whole layer with white
ok now
filter - render - lighting effects
use the settings below. only change maybe the colours (to fit with your base colour)
set it to about 20% opacity and luminocity blend mode
layer 4
ok we want the white dots again from layer 2 so again duplicate the layer. disable emboss settings, and set it to normal blend mode
now take out your pen tool set it to "paths" mode
draw a line accross the map
(then loop it around off the outside of your map to make a full circle)
use the convert point tool to make them nice and curvy
right click near your line and select fill path, fill it with white,
now just press delete a few times to clear the path,
rince and repeat...
magic wand select the non-white bits. and paint bucket them black
press ctrl+i to invert the image
set it to darken blend mode
i added a glass distortion to my layer.
and change the opacity
now you may have noticed. but i think i went a little overboard with the yellow here
so im going to do a bit extra to mine.
first add a layer 5
fill it grey
and make set it to saturation blend mode
right click on the layers panel
and merge visible
now fiddle with hue saturation and brightness
finally i added a crater that i could swear i made and uploaded to this topic... anyway its a tiff image and i set it to colout burn
i know mine doesnt look terribly good because i rushed through it. but some general techniques are here. add your own little bits.
i recomend firstly that you try to involve your heightmap in some way.
secondly i recomend you try this out on like a 1024 x 1024 image before you try on your full size texture
thirdly before you try it on your full size texture. set up your scratch disks!
i have 2 GB of ram and 30 GB of scratch disk/virtual memory set up in photoshop.. never crashed once.
also with the dual proccessor ness i can do other stuff while i wait for the proccesses to complete
oh yeah also. if your gonna follow this... print it out. (helps alot
