Do you think this generator will ever let you set the water-to-land ratio?

This is the most realistic looking generator I have come across, but I feel like I have to spend ages cycling through maps to find something anywhere near the ratio I want.

yeah that would be really useful

I don't think there are any way to specifically specify water percentage, but I found this in the manual:

"The initial altitude (-i) option specifies the initial altitude of the corners of the box, before subdivison. Increasing
this will increase the amount of land on the planet and vice-versa. The default value is -0.015, which gives a slight
preference for water. Changing this value by +/- 0.01 will change the water percentage by 5-15% (depending on
the planet in question). If you, for example, want a planet with 70% water, you can make a world map using the
-pp option (which prints the water percentage, see below) and adjust the initial altitude using the -i option until the
indicated water percentage is 70."

For anyone that comes across this, the manual page with the -i parameter (which by the way, default is actually -0.02 as defined in the command line options section, as opposed to the -0.015 defined in the section describing the use of the -i # parameter) is for the command line downloaded version of the planet generator (which is very very useful since you can go much larger with bigger generated maps)


For the website version, you can follow the command line manual guide by using the Peters projection (-pp as defined in the guide) and then the water % will be shown above the generated map. For the command line version, this is shown in the command line after a successful generation.

You can then change the value of "Water Line" around (More positive = drier; More negative = wetter) until you find a water% you find suitable. Earth is at 71% by comparison.

And for posterity, in the command line version, Water Line is set by the -i # parameter (default -i -0.02)
