Latitude in Snyder (page 15): For the "normal" Mercator projection (on the ellipsoid) this function defines the spacing of the parallels: if the length of the equator on the projection is (units of length or pixels) then the distance, , of a parallel of latitude from the equator is The isometric latitude is closely related to the conformal latitude : The formulae in the previous sections give the auxiliary latitude in terms of the geodetic latitude. The expressions for the geocentric and parametric latitudes may be inverted directly but this is impossible in the four remaining cases: the rectifying, authalic, conformal,
What on Earth! What on Earth! What on Earth! (French: "La Terre est habitée!") is a 1966 National Film Board of Canada animated short co-directed by Les Drew and Kaj Pindal. The film is a mockumentary, introduced in its opening credits as produced by the "National Film Board of Mars" that takes a humorous look at car culture from the point of view of fictional Martians, who mistake automobiles for Earth's true inhabitants and people as their parasites. It attempts to examine the sociology of the automobile as the dominant species on earth, and makes wild guesses about the lifestyle, feeding habits, mating
