The cone is cut opposite the specified longitude and laid flat, so it appears like a pie section. The scale at the center of the map is the same as for ortographic and stereographic projections. Using conical projection, all of the planet is mapped onto a finite section of a cone, so you can make complete world maps. It is, however, not really suited for this, as latitudes far away from the specified latitude are very distorted. Regardless of the projection used, on maps of small sections of the planet, the scale will differ very little across the map and the distortion will be small.
Orthographic projection is used.
Options controlling colours and gridlines are ignored. This option is intended to produce input to programs that e.g. show 3D views of small areas of the planet. This map is 1 lines of 24 characters. The program tries seeds starting from the specified and successively outputs the seed, rotation and initial altitude of the best current match, together with a small map of this. This is all ascii, no bitmap is produced.
