I'm trying to create 3 different projections for the EASE-Grid projection:
http://nsidc.org/data/ease/ease_grid.html#nh_map
Northern Hemisphere Azimuthal Equal-Area Projection, Southern Hemisphere Azimuthal Equal-Area Projection , and Global Cylindrical Equal-Area Projection.
I know you can create a custom projection in d3.js but how do i even start this? Any help would be awesome!
