Which is the best description of the Mollweide projection?
The Mollweide projection is an equal-area pseudocylindrical map projection displaying the world in a form of an ellipse with axes in a 2:1 ratio. It is also known as Babinet, elliptical, homolographic, or homalographic projection. The projection is appropriate for thematic and other world maps requiring accurate areas.
How is the central meridian projected in Mollweide?
Mollweide is a pseudocylindric projection. The equator and the central meridian are projected as two perpendicular straight lines. The central meridian is half the length of the projected equator. Two meridians, 90° east and 90° west of the central meridian, project as a circle.
When did Karl Brandan Mollweide create the projection?
The projection trades accuracy of angle and shape for accuracy of proportions in area, and as such is used where that property is needed, such as maps depicting global distributions. The projection was first published by mathematician and astronomer Karl (or Carl) Brandan Mollweide (1774–1825) of Leipzig in 1805.
Which is the best projection for a country?
You can choose between the following map projections: Mollweide – a pseudocylindrical projection that maintains equal area of land masses. Areas near the top and bottom edges can be distorted
When did Karl Mollweide invent the projection?
The projection was first published by mathematician and astronomer Karl (or Carl) Brandan Mollweide (1774–1825) of Leipzig in 1805. It was reinvented and popularized in 1857 by Jacques Babinet, who gave it the name homalographic projection.
When was the first version of Mollweide made?
The projection is appropriate for thematic and other world maps requiring accurate areas. Mollweide was first introduced by Karl B. Mollweide in 1805. It is available in ArcGIS Pro 1.0 and later and in ArcGIS Desktop 8.0 and later.
