Bonne projectionn.

Brit.

/ˈbɒn prəˌdʒɛkʃn/, U.S.

/ˈbɑn prəˌdʒɛkʃ(ə)n/,

/ˈbɑn proʊˌdʒɛkʃ(ə)n/

Forms:

α. 1800s– Bonne's projection.

β. 1800s– Bonne projection.

Origin: From a proper name, combined with an English element. Etymons: proper name Bonne , projection n.

Etymology: In α. forms < the genitive of the name of Rigobert Bonne (1727–94), French cartographer, who refined the theory of this type of projection + projection n. In β. forms < the name of Rigobert Bonne + projection n.

Now chiefly historical.

A type of map projection in which parallels are equally spaced circular arcs, and lengths and angles are preserved along a central meridian and parallel (but are progressively more distorted away from these).
