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,
The Longest Voyage it is "nearly unmatched" in science fiction for its "lyricism, compassion, subtlety, thoughtfulness, and above all the relish it takes in the bristling strangeness and wonder of the world". Steven H. Silver commented that what distinguishes "The Longest Voyage" from similar stories is that "Anderson provides strong motivation for both the explorers and the natives".
