  Size/Zoom   Sets resultant bitmap size and zoom in.
  Map Size   Determines the bitmaps size width/height in pixels.
  Auto Zoom   When this is checked, your map shape will remain the same even if you change your map size smaller or larger, provided that no other feature variable has changed.
  Zoom Level   Determines the zoom in multiplier (larger is closer). A higher zoom will reduce the number of interior points, thus making map generation go faster.
  Features   Sets the overall land and water features.
  Land Coverage   Determines what percentage of the map is covered by land.
  River Coverage   Determines what percentage of the resultant land has rivers.
  Islands Proliferation   The level that the land masses are broken up. This is actually the inverse of the "Twelve Points Range" which determines the maximum amount that one of the twelve original starting points (which form the vertices of the twenty triangles), can vary from the "Center" value.
  Share Cap   Recursive 'share', the inverse of which is used in generating points.
  Elevation Offset   Raise or lower land masses by +-25%. This does not affect sea level. So, if you lower land, then more land will be underwater and reversely, if you give a positive value, then more land will be above the waterline. If you adjust the sea level by the same amount, the effect will be to increase or decrease the various vegetation levels. This is most noticable by an increase or decrease in the mountain peaks. As this number gets larger, it will 'squish' all the elevations toward either the maximum or minimum allowed. This will reduce the differences between climates and vegetation.
  Sea Level Offset   Raise or lower the sea level +-25%. If you lower sea level, more land will be exposed, conversely, raising the sea level will submerge more land. Adjusting this number will have an effect on climate and vegetation.
  Advanced   Sets additional features and effects.
  Draw Grid Lines   Enables the drawing of equal area squares along the latitude and longtitude of the map. You can select either gray or black as the color.
  Altitude Shading Multiplier   Multiplier to apply to shading due to altitude difference. The higher this number, the sharper and more realistic the differences in altitude will be, the lower, the more blending occurs and a smoother, flatter, less-realistic appearance will occur.
  Climate Map Highlighting   Highlights the jungles, deserts, wastelands so that less blending occurs along the boundaries of the selected color for those climates. For Sea Temps, it highlights sea surface temperatures along the latitudes with lighter shades near the equater and darker shades of your selected water color near the poles.
  Iterations   The number of successive times the fractal generation will run. This number affects 2 things, the speed and therefore the time it takes to generate a map and the overall definition of the various vegetation levels on the climate map. The higher the number of iterations, the more blending or detail will occur between various vegetation levels on the climate map. So, if you are just looking for a good land/water configuration, then set this number to 10 to rapidly prototype planet shapes. Then, once you have zeroed in on a good shape, set it up to at least 40, to get some good definition on the climate areas.

Some suggested values:   if map size = 1024 then set iterations to 50-70, 1200 then use 60-80, 1200+ then use 70-100
  Temperature Offset   This will raise or lower the overall base temperature for the planet by +- 40 Celsius.
  Seed Number   Choose either a random or fixed long integer for initialization. This variable, more than any other, will radically affect everything about your map. It will be used to determine both the land/water shapes and elevations as well as the climate and vegetation levels. It is suggested that you set this to random to find a suitable map, then once you have one you like, deselect it and fine tune the other options.
  Enable Seasons   Check this to have seasons simulated in the climate map. The active season listed is determined by the northern hemisphere (upper half) of the map. Enabling this will allow you to set the Temp Swing and Active Season options.
  Temp Swing   The maximum add/subtract to base temperatures. See Seasons.
  Active Season   What the active season or half-season is for the northern hemisphere.
  Colors   Sets the climate and relief colors for various terrain and altitudes.
  Climate/Vegetation   Climate and vegetation colors are arranged from highest to lowest altitude and from left to right. The middle colors of forest, grasses, and jungle, reflect the densest vegetation. Blending of adjacent areas will occur unless highlighting is selected.
  Relief/Altitude   Relief and altitude colors are arranged from highest to lowest altitude and from left to right. No blending of adjacent areas will occur and various shades of the water color will be used to delineate below sea level depths.
  Filepaths   Sets the maps and options file paths for open/save. Stored in the registry.
  Maps Path   Sets the path for opening/saving map (bmp) files.
  Options Path   Sets the path for opening/saving options (cfg) files.
