I would like to map distribution of some specimen over Africa at a
resolution of 100 km x 100 km (or even down to 25 km x 25 km): I believe I
need an Equal area projection. My original files, with the data, are .csv,
with lat/long + measurement (real number). I need to carry out some file
(.csv) transformation between projections.
I gathered some information, and ended up with the following list of
2) Equatorial Lambert Azimuthal Equal Area
3) Albers Equal Area (Conic)
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?
I already read the usual stuff (like UGSPP 1395 document - Map Projections -
A Working Manual and co.).
