Mollweide|ˈmɒlvaɪdə|
The name of Karl B. Mollweide (d. 1825), German mathematician and astronomer, used in the possessive, attrib., and absol. to designate a homalographic map projection in which the surface of the globe is represented by an ellipse, with lines of latitude represented by the major axis and straight lines parallel to it (spaced more closely towards the poles) and meridians represented by the minor axis and equally spaced elliptical curves.
1901C. F. Close Map Projections ii. 22 (heading) Homalographic equal-area (Mollweide's). Sometimes called Babinet's. 1912A. R. Hinks Map Projections vii. 73 For the whole world on a single sheet we have Mollweide, which is useful for distribution diagrams, but can scarcely be called a map. 1937F. Debenham Exercises in Cartography x. 118 Draw an interrupted Mollweide projection to show continental areas with the least distortion. Ibid., Make an approximate graticule on the Oblique Mollweide suitable for showing the British Empire Seas. 1947H. D. Thompson Fundamentals Earth Sci. v. 52 Mollweide's Homalographic equal-area projection (1805) shows the entire surface of the earth inside an ellipse, the major, or equatorial axis of which is twice as long as the minor axis. 1960F. Land Lang. Math. vi. 70 Mollweide's map..is an equal-area map, preserving area relations at the expense of shapes. 1971R. W. Purton Let's look at Maps & Mapmaking 14 Mollweide's projection can be drawn with any line of longitude as its centre and can be used to draw attention to one particular part of the world. |
