Bottomley projection
text:
The Bottomley map projection is a pseudoconical equal area map projection defined as:
- x = ρ sin E sin φ 1, y = π 2 − ρ cos E where
- ρ = π 2 − φ, E = λ sin φ 1 sin ρ ρ and φ is the latitude, λ is the longitude from the central meridian, and φ1 is the given parallel of the projection which determines its shape, all in radians. The inverse projection is then given by:
- φ = π 2 − ρ λ = E ρ sin φ 1 sin ρ where
- ρ = 2 + 2, E = tan − 1 . Parallels are concentric elliptical a
