What does this do??

[Titus Livius]

Hi, right now i am modding my map and ran across this in descr_terrain.txt:

}
roughness
{
min 50.000
max 200.000
}
fractal
{
multiplier 0.500
}
lattitude
{
min 22.000
max 56.000
}

does anybody know what they do? Help would be appreciated

This determines how the battle map is generated. Roughness min/max are self explanitory, and fractal multiplier seems to be a random number seed. I have no idea what the lattitude parameters are for. I'm pretty sure there is a thread on this in the tutorials section.
