I'm not sure what the mosaic settings in Photoshop are.
I have attached the Gimp dialog. I found the best effect was as selected (for buildings.
I also did a quick test running the mosaic filter three times. Also attached. Think I'll keep playing as there seems some potential for filling large areas easily. There has to be a reasonable programmatic way to generate streets.... might have to look into L-systems and fractals again

Hi all,
Looks like it has been a long time since anyone posted in this one...so I want to drop in and say thanks for the tutorials! Just finished reading these and am going to try them out tonight. I like the results and method - I truly feared trying to draw all of the little buildings of a big city by hand.
I'm new to this site and to computer mapping in general and think this one will help me with my current project a great deal. Looking forward to reading the rest of the impressive-looking tuts on here and trying out some of the techniques. Thanks again!

Nice tutorial!
Wow--as you can all see, I don't "haunt" my old stomping grounds very often (I'm like Haley's Comet, I guess), but I was astounded and flattered to see so many nice comments about this tutorial. Thank you.
But more importantly, what a bunch of great maps you've all made! Nice going! Excellent work, everyone! Keep it up!

Download problems; doodles while I wait.
I am attemting a download of the tutorial for a fourth time. I keep getting 2-3.5 MB in and having the download just stop. I have tried both parts.
While I was waiting I decided to play around with the road thing. I, too, thought Mosaic would be a natural filter for getting sort of random roads.
Here is what I did, just a few steps, and the results:
Using the Gimp:
New Image, 400x400 pixels, RGB, fill with black (000000).
Set the grid to 20 pixels, and snap to grid, and put in a rough grid of magenta (ff00ff).
Ripple (Filters ... Distort ... Ripple) with Antialiasing, edges wrap, sine wave, period 90, amplitude 6, in both horizontal and vertical.
Duplicate the layer. Turn the background layer's visibility off.
Apply Mosaic (Filters ... Distorts ... Moaic) with Antialiasing, Octagons & squares, tile spacing = 2, tile neatness = 0, light direction = 135, color variation = 0. Tile size and height you can play with. For these I used both equal to 20.
Select All (ctrl-A). Copy (ctrl-C). New Layer with fill color ccbb77 (or whatever color you want your roads.) Paste (ctrl-V). Fill with foreground color (I used 552211) (Edit ... Fill with FG color). Anchor layer (ctrl-H).
I don't like the look of the darker color, because there was too much transparency in the mosaic, so lets select the background (road color) by color and paste it onto a new layer filled with the darker color. If I wanted to, I could texture that color here, as well. Discard the other layers. Flatten and save as a JPG. Not worth even saving as an .xcf file because all the steps are so easily duplicated.
Voila: Random_roads1.jpg
The pattern could be more regular if I were more careful with my initial magenta grid, and if I used neater tiles. I was going for random here, starting with something easy to draw in an orderly fashion.
Random_roads2.jpg is with a more regular starting grid and squares for the mosaic instead of octagons.
It seems that attachments appear in reverse order to the order you attach them. Now I know.
correction
When I applied the mosaic filter in the above examples, I did it with color variation of .2, (unchanged from the default,) not zero, as stated above.
And it seems part 1 of the tutorial just finished downloading successfully. On to part 2.
