Dear friends,

I would like to use it to map distribution of some specimen at a resolution of 
100 km x 100 km (or even down to 25 km x 25 km).

I gathered some information, and ended up with:

1) Sinusoidal
2) Equatorial Lambert Azimuthal Equal Area
3) Albers Equal Area (Conic)
4) Mollweide
5) Cylindrical Equal Area

I do not really know which one to choose. What do you recommend?

For each of them, which ellipsoid  and datum would you choose?

Regards
--
