The map I made to base my other Ice Age Earth image on. I don't want to release the full res version of this map to the public right now, but here is a smaller 1024x512 version. This version only has 1/256th the detail of the original.
The ice is pretty simple to do in photoshop. I make a layer that's solid white. Clip the shape I want out of it, then overlay it with a mostly transparent edge detection of the black and white elevation map to texture the surface.
That's a good idea. I loved dinosaurs when I was a kid, I'm surprised I never thought of doing that. It'd be easy to choose which side of the world to focus the image on too since there would only be one continent. The question would be which era?
not in the glacial periods,only in the interglacial periods,when glaciers were vanishing, the last was from 12.000 years ago to 4.500 years ago. my Concept shows how Africa looked like in that period: [link]
I found a way to use the Gimp and another program to create a fairly nice rotating version of the ice age earth map in shockwave flash. It's rather ragged, especially at the edges, but interesting to watch all the same.
Nice, I dabbled with making animated planets using svg. The results were less than stellar. I got one that I could rotate using the arrow keys and it had a nice cloudless atmosphere, but it was very grainy and small.
I see now. But when your finished with the ice age earth, could you try to make a ice less earth? That would be interesting... Also, would you kindly check my channel (is it called channels?), and tell me how to improve my textures?
To see what a iceless Earth would look like I made a threshold map. For a 70 meter rise (the max theoretically possible) the difference is hard to notice. Just a few areas produce a noticeable effect from space. To see what I mean look at this map: [link] The red and yellow areas would be water. Doesn't make for a very interesting pic.
For my maps I make extensive use of layers and alpha masks, based on elevation maps. Some knowledge of meteorology helps. Contrasting the known meteorology of the different planets that have atmospheres helps you figure out where climate zones might appear on a planet.
