View Full Version : Half of Terran World Map

Hello all. I've been here a couple of times seeking help with my world map. The world I am designing is Earth 50 million years in the future, and will be utilized in my fantasy setting (for gaming and possibly for setting my novels in).

I started with a Dymaxion map progression and outlined each continent/plate on a separate layer. This allowed me to rearrange the continents as tectonic projection projects (I couldn't just start with one of the projected maps because it was in a more standard projection model, which was causing the land at the edges of the map to be severely distorted).

The map's scale is 1 inch = 4146.76 miles, or 6673.57 km (the map is 6 inches tall). The points at the top and bottom of the map are the North and South poles, and you can see where the map was spread to flatten it. The marks on the sides note the arctic circles, the tropics, and the equator. The brown on the map notes mountain ranges, but not altitude (I'll later be adding layers for altitude, terrain, and climate).

Currently, I would like help with spicing up the coastlines, as well as ideas on how to camouflage what is obviously Africa's coastline on the Eastern portion of the continent.

Oh, and for the perceptive, I did switch the poles. There is research showing that this may have happened many times in our past, and I'm using it as one of the many events that helped reshape the world and remove almost all evidence and knowledge of previous cultures.

Thanks for any help you can offer.

I also wanted to add a "great work" to all of you here. I've seen some beautiful maps here, and I hope I can achieve a percentage of what the CG's best have.

50 Million Years ahead?

That sounds like a serious call for geologists first of all, ever since continental drift will have been a serious issue.

Btw - does the Sun hold out that long? Can't remember whether it was 5 million or 5 billion years...

If you're interested, the research can be found http://www.scotese.com/Default.htm. It would be kind of silly for him to have a 250 Ma map if the sun wasn't going to be around that long; I believe the sun's got billions of years left.

I'm actually researching theoretical evolution as well; there are a number of biologists who have written books on what animals could be like in the future, including an Animal Planet special The Future is Wild (http://en.wikipedia.org/wiki/The_future_is_wild).

I don't try to explain magic and such with science (aside from simple handwaved psudo science if necessary). The fact that my setting is Earth in the future is more to give me structure than it is a huge portion of the setting: I'll never come out and say it in game, though there are clues and echoes of the past which do affect the present.

Either way, any ideas on how to spice up those coastlines?

The sun lasts a good 5 billion years more. About a billion years from now, though, Earth becomes uninhabitable as the sun's perpetual increase in brightness drives the inner ege of the habitable zone past Easrth's orbit.

Check out RobA's tutorial on how to build a not-so-random coastline. (http://www.cartographersguild.com/showthread.php?t=875)

This sounds ideal for your purposes since you can start with images of existing continents and by playing with the settings, make detailed coastlines which hold the main forms of the continents but differ in the detail.

You will need to download Gimp (free download) if you have not already got it.

I tried following the tutorial in Photoshop, but it wasn't working, even after someone refined it for Photoshop (I'm misunderstanding one of the steps I believe).

Thanks. I finally got it to work, but it isn't doing very much for me, since I'm dealing with such a large scale. I did discover that I can trace out the continents and use the Ocean Ripple distortion to create some random coastlines, then find edges to finalize. I'll be fine tuning things, see how it all turns out.

Hmmm, must try that ocean ripple trick. When you say it's a problem of scale, do you mean that your document is at too high a resolution for the cloud filters to give the effect?

No matter what resolution I try, the cloud details are just too big. I figured out a workaround; I fill the whole layer with the clouds, then use transform to scale the selection down to 1/4th, then tile it. GIMP allows you to play with the detail of clouds, but I can't find a way to do it in Photoshop.

The ocean ripple trick is only good for islands I found; it makes continents too uniform in their randomness ... as oxymoronic as that sounds.

It's a pity the PS cloud filter doesn't have settings, I use a plug-in filter (http://www.alienskin.com/xx2/xx2_filters.html)for clouds which has a lot more options. Very good plug-in set, which I'd highly recommend to anyone. Works with PSP too.

Thanks for that link. I'm not in a position to spend money on this now (more so than PS already cost me), but I'm happy to see other resources.

Oh, and here's what I came up with for my new coastline.

I see the mmcloud filter is not at the website I linked to.

Thanks RobA, much props. I'll fiddle with it and see what it can do. In the mean time, anyone have feedback on how things look so far? Should I use the coastline trick to make the mountains a bit more organic as well?

I'm going to be going through all of the tutorials here (in fact I intend to go through RobA's "Using GIMP to Create an Artistic Regional RPG Map" tutorial and see how it feels). But maybe you all can give me a few pointers on the things I want to do on a global scale:

1: Map Elevation. Along with the mountains, land, water, and air/water currents, elevation will help me in setting climates (I have a few resources that aid in getting general bands, maybe others have better ones?).
2: Climates. Plotting out general climate tendencies like humid tropical, humid temperate, hot and dry, and cold and dry. I have real world maps and a few resources to help.
3: Biomes. Forest, Grassland, Desert, Tundra, you know it all. Climate helps here.

I'm not looking for regional level detail yet, but I'd like to have a nice map with multiple layers for all the purposes I could need. I'm shooting for believability over accuracy, but I want things to look organic.

Thanks all.

Some Links (culled from some old threads)...



Check out this thread (http://www.cartographersguild.com/showthread.php?t=641) and possibly Geoff's Climate Cookbook (http://www.cix.co.uk/~morven/worldkit/climate.html).


Another good reference for both climate and geology is Expeditious Retreat Press' A Magical Society: Guide to Mapping (http://e23.sjgames.com/item.html?id=XRPFREE2), which is a free-to-download chapter from the larger A Magical Society: Ecology and Culture book.

(And if you like that one, try also A Magical Medieval City Guide (http://e23.sjgames.com/item.html?id=XRPFREE1).)

The coastlines look great, although I think they need a little cleaning up in some areas where the lines do something funky.

I actually have the books from Expeditious Retreat Press, those are the main parts of my climate resources. I'll look over the others.

Where did you think the coastline looked odd?

Attached is a bit of example coast that looks odd -although it might just be an artifact caused by the scale of the zoom.

Thanks for pointing that out. I just need to delete the white in those coastal lakes. Those islands were altered using ocean ripple; that's the sort of effect you can get (that very broken island chain to the south of three was done with the cloud effect, but I had to scale the clouds down to a very small area.

I discovered another effect with the clouds that might be very useful for some people. If you want to make an island chain that has many random islands, like the Philippines for instance, that all go in one direction (as most island chains do), here's the trick: make a white area for where you want the islands, and blur it enough that the blur extends through the whole white area (you can limit how far the blur goes away by wrapping it in a lasso first).

Then, when you make your cloud effect, scale it down so it is only under the island chain in question. If you scale it non-uniform, like turning it from a square to a rectangle, you can create longer islands that flow in mostly the same direction. Also, I haven't tried it yet, but I think if you were to use one of the transforms to give it an 'S' curve or something, you could create the same effect in the islands.

Thanks for being here guys. You've given me a new hobby. Maybe I'll get better with Photoshop soon.
