View Full Version : A big section of my atlas is finished

This set of 5 maps brings my total up to 40 regional maps completed. Probably about halfway done.

This is the continent of Kondonga, which is dark, wild, and dangerous. There are tangled jungles, dark forests, high mountains, reef-bound islands filled with headhunters, vast grasslands raging with wildfires, and other great stuff.

The first map here is of the northern jungles of the continent. The second map shows the dense forests of the west, which are populated by the ape-like Honga and legions of Giant Siafu ants. The third map shows the southern coast of the continent, with its high mountains and coral-filled seas. The fourth map is the grassland to the southeast. Finally, the fifth map shows the chain of islands to the south of the mainland (which I think I might have posted here before).

Enjoy!

So immaculately done as always. I think th e45 deg lines on map 2 look odd - was that intentional or due to that cloud fractal math going mad again.

Edit -- Not sure if you realize that if this is an issue then its fixable.

Very very pretty.

I saw just your post title and hoped this was your work.

How did you do that! Those ridges really bother me, they seem so artificial.

Well I will admit that it takes some specialist tools. I have a program called a spatial filter. You can get them and I think (or so some people have alluded to) photoshop has some settings in it to do something like this. I wrote the program that I use - its very hard to explain how it works tho, or how to use it. If you know about Fourier Transforms then its easy else it would be hard work.

But if you want to send me any maps that need fixing then I could process them and send them back. What the program does is analyze the image and work out where certain patterns are. I told it to look for 45 deg lines and then it wipes them out. Since in this case the grid and most of the map detail is not in that pattern then it leaves it alone. The only problematic area is the coast top left where its also at 45 deg.

So if you still have the gray mask bit without the grid, text, coast or lines and just have the base floor then I could process it with no changes to the detail layers at all and then you could substitute them back afterwards.

Attached is a pic of the worst part of the map processed. The text has some background lightness issues and the green and blue fo the coast has transposed a little but if the text is on a different layer then the only effect that you would have is the coast and sea transposing. Since your sea is one color then you can fix that and the land color change is pretty minimal I think. Much better than the big lines on it.

Would you be so kind to fix up a few of these for me? I've gone through my maps (both finished and in-production) and found this problem on 5 of them. I could PM the greyscale relief files to you if you would be willing to clean them up.

Thanks a bunch!

Wow... fantastic work.... I doubt I will ever have command of Illustrator like you do, not enough to complete such fabulous maps with them....I love Illustrator but you my friend take the program to a whole other level ... like supra ... not super... supra :D

No problem - email a zip of them to 'support' at 'viewingdale' dot 'com' and ill get them back in a short while.

RR, you're awesome. Rep to you for being so helpful!

edit: or not. I guess I already repped you recently...

Rob has sent some of the worst parts of the line ridged areas over. Although I have posted the full results back, here are some small swatches of the areas and how they were modified. I hope this helps. Some of the areas had some severe lines on them which practically obliterated the underlying features. Using a spatial filter will always destroy some of these features but with the hope that it will destroy the unwanted bits more and thus raise the overall signal to noise quality of an image. Some sorts of badness are really hard to separate from the good so thats when it fails to achieve a good result. Other times its brilliant. I think the best is for things like removing halftone from images where the unwanted bit is very regular and at a significantly different frequency from the good part of the image. These images had a mix where sometimes it worked better than others. You can judge for yourself tho.

I'm impressed!

I tried the second swatch using the GIMP using the FFT plugin.

I used a thresholded then blurred copy of the frequency domain image as a mask on a blurred copy of the frequency domain image.

I think I overdid it :P

Here is your swatch, with my effort at the bottom:

I've used this plugin to remove screening noise from images before. In case anyone wants to try, here is a link to wikibooks explaining how to remove coherent noise using GIMP (http://en.wikibooks.org/wiki/The_GIMP/Remove_coherent_noise) and here is the link to the fft plugin I used.

That sounds like a similar process to what I did on mine. Its probable that Gimp has exactly the same process built into it. I would advise people to try it as sometimes, for the right instances, it can be miraculous. Your result is very good indeed. The only difference is probably some slight different tweaking in the filter image used. I thought somebody said that PS had it but at least I know Gimp has this for sure now.

That is amazing! This will be very helpful for the odd FT map which requires redoing. Any chance that it can be posted in the tutorial section for easy reference?

Well... despite those minor glitches, these maps are indeed handsome. It's amazing how thoroughly you've mapped this world.

Qustion... why do you do it? I think it's great, but I wonder what it's purpose is.

Yeah, I really like your work! what software are you using? Illustrator? Are all those rivers done by hand then or is there some fractual program you're using? It'll be good to get an idea of your work flow if you don't mind.

great stuff!

thanks for showing

Thanks Karro. It doesn't really have a purpose. I just do this for the fun of it. When all of the mapping is complete I would like to self-publish an atlas, but that is a long way off.

I did a tutorial a while back... it's here. (http://www.cartographersguild.com/showthread.php?t=1577)

gorgeous stuff here. that's it - i need to learn how to use illustrator!
