Thank you! Very nice, and I shall try it out.
I thought that you would be interested in my own past efforts, so I
shall put them too in p.b.scene-files too. Look for Geomorph.

It works nicely though.
One thing you can improve: If you want your camera to be *always* above
ground, change the following code lines to:
#declare cam_location = <-100, 900000, 0>;
#declare cam_pos = trace(land_and_ocean, cam_location, -y);
camera{
location cam_pos+(y*cam_height)
look_at cam_pos+(y*cam_height)+cam_look_at
angle 50
}
sphere{cam_pos+(y*cam_height), 0.1 pigment{rgb 0 transmit .1} }

Another comment I would like to make is to comment out all jitter,
aa_level and aa_threshold in the media. Other than the default values,
they seriously slow down the render, make the image granular, and do not
add much to the final result.

I know that commenting out the quality settings will speed it up, its just that
the quality isn't that good. On the other hand thank you for the camera set up!!

It's not bad either. I never touch them in fact and only play with the
samples amount to increase or decrease the quality of the render.
However, I suppose this might be debatable in the end :-)

I posted an image in p.b.i.
Forgive me for having changed a couple of things in your code in
addition to those mentioned earlier ;-)
1- I made the code 3.7 ready by adding the #version, assumed_gamma, and
radiosity settings I am familiar with;
2- I changed rgb to srgb. Not essential but it deepens the colours of
the textures;
3- I changed somewhat the sun code:
#include "CIE.inc" // for SunColor. Comes with Lightsys IV
#declare SunColor = Blackbody(6500)*3;
#declare SunAlt = 60;
#declare SunAzm = -120;
#declare SunPosition = <0, 0, -1>*10e6;
#declare SunDis = vlength(SunPosition)*2/215;
#declare sun =
light_source {
SunPosition
color SunColor
rotate x*SunAlt
rotate y*SunAzm*clock
parallel
/*
area_light
SunDis*x, SunDis*z,
5, 5 // total number of lights in grid
adaptive 1 // 0,1,2,3...
jitter // adds random softening of light
circular // make the shape of the light circular
orient // orient light
*/
looks_like {sphere {0, 1001 pigment {color SunColor} finish {emission
1}}}
}
object {sun}
4- I changed the landscape material. See also the slope documentation in
particular for Hi_slope and Lo_slope. I first made the material into a
macro:
#macro land_material(Min,Max)
material {
//rock
texture {
pigment {
bozo scale 450 turbulence 2
color_map {[0 srgb 0.3][0.5 srgb 0.5][1 srgb 0.8]}
}
finish {diffuse 0.6}
normal {granite 0.8 scale 0.01}
}
//moss
texture {
pigment {
slope {<0,-0.9, 0>, 0.0, 0.5 altitude <0, 0.1, 0>, Min.y, Max.y}
pigment_map {
[0.3 srgbt 1]
[0.3 bozo scale 54
pigment_map {
[0 bozo scale 0.2 turbulence 1 color_map {[0 srgb <0.5,
0.6, 0.25>*4 ][1 srgb <0.5, 0.8, 0.1>]}]
[0.5 bozo scale 0.05 turbulence 1 color_map {[0 srgb
<0.5, 0.55, 0.3>][1 srgbt 1]}]
}]
}
}
finish {diffuse 0.8}
normal {granite 0.1 scale 0.01}
}
//snow
texture {
pigment {
slope {<0, -0.5, 0>, 0.0, 0.5 altitude <0, 0.5, 0> Min.y, Max.y }
color_map {[0.5 srgbt 1][0.55 srgb 2]}
}
finish {diffuse 1 brilliance 0.1 specular 0.5 roughness 0.002}
normal {granite 0.5 scale 0.005}
}
}
#end
Then I commented out the material in the land object, and added after it:
#declare Min = min_extent(land);
#declare Max = max_extent(land);
#declare land =
object {land
land_material(Min,Max)
}
See the resulting image in p.b.i.
