Jason’s work here is so exciting because it demonstrates another path to escape the tyranny of Mercator’s projection. Using reprojection on the client, you can take any Mercator tile source (that’s nearly all of them) and refit it to a projection more appropriate for your application. For example, Alber’s conic projection is equal-area, which is a good choice for choropleths. In effect, client-based reprojection gives you the convenience of multi-resolution tiled geospatial data without being beholden to a specific projection. This is huge.
