ProjectionKind

ProjectionKind = "equirectangular" | "mercator" | "transverse-mercator" | "albers" | "albers-usa" | "conic-conformal" | "conic-equal-area" | "conic-equidistant" | "azimuthal-equal-area" | "azimuthal-equidistant" | "gnomonic" | "orthographic" | "stereographic" | "natural-earth" | "equal-earth"

Defined in: spec/coord.ts:8

Named map projections, by the family a reader would ask for.

The projection mathematics is cartography and belongs in a math/* package; this is the reference a spec carries so that a renderer able to project can find one, and a renderer unable to project can decline cleanly.
