Rationale

The method below is to accurately display your FT3 map at any projection as a CC3+ map, with all the climate zones, altitudes and major rivers in their correct places no matter what the projection, and also to allow fine tuning the map in a way designed to add extra detail without changing the original FT3 map to any great degree.

The method requires as much detail in creating the FT3 map as possible – see articles on designing FT3 maps. Especially, this requires attention to altitude, climate zones, islands and rivers.

The most popular projections are:
• Equirectangular – increasingly inaccurate as you travel away from the equator
• Hammer – distorted increasingly as you travel to the east and west borders
• Sinusoidal – accurate and not so distorted, but discontinuous. Can be used to make an actual globe, especially the 18-way Stereographic Gores.
• Orthographic – allows you to centre on the landmass in question and see it most accurately of all in a continuous fashion. Used also to make maps centred on the North or South poles.
• AE Hemispheres – presents the map as 2 hemispheres (E and W). For best results, make your original draft map in FT3 as an AE Hemisphere projection, and then refine it at the equirectangular projection. This enables you to make sure there is not too much land overlapping each hemisphere – see below for preferred (left) and not preferred arrangements (right).
