190 GEODETIC COORDINATES AND PROJECTIONS. VIII. A projection devised by Bonne is constructed in a similarmanner to that of Flamsted, except that the parallels areconcentric circles. The center of these circles is in themiddle meridian and at a distance of a cotL from the middleparallel whose… … equatorial radius a, and the radius of any other parallel isa ± d, where d is its distance from the middle parallel. Thismethod gives trapezoids of equal area and an orthographicprojection along the middle meridian and parallel, but theshape becomes rather awkward where a large area is…
