Geofiction Base Maps using Wilbur

[a2area]

Here is what a couple more incised flows did applied at different settings to 3 different elevation groups. I think it gives a better feel for this scale and I am happy with it for the purpose. Most of all what i'm looking for is relative consistency from map to map that will stand up at a wider scale (continental) so it wouldn't be in my best interests to start making the landscapes too unique. And I suppose that is where the "fiction" in geofiction comes in! Unique natural featurs that could plausibly fit into this overall landscape don't necessarily have to be featured on the map in perfect topographical scale as much as i would love that.

Maybe someday Wilbur and Fractal Terrains will have a baby (-:

.... one question i do have that i couldn't find a satisfactory answer to:
I have been outputting gray-scale image from FT to open in wilbur.. works fine... BUT, I would like to have wilbur know where sea level is automatically instead of having to mess with the scale or range which wilbur doesn't remember the next time you open the file. I would simply make my color scheme in FT conform to this... output... input to wilbur and boom.. perfect sea level.
How do i do this? Seems like it should be obvious like (ie) "set sea level : RGB value" or something.
It doesn't make sense to have black as the default sea level when you have negative elevations (depths).
