Roussilhe oblique stereographic projection
Encyclopedia
The Roussilhe oblique stereographic projection is a mapping
projection
developed by Henri Roussilhe in 1922. The projection uses a truncated series to approximate an oblique stereographic projection
for the ellipsoid. The projection received some attention in the former Soviet Union.
The development of the Bulgarian oblique stereographic projection was done for Romania by the Bulgarian geodesist, Hristow, in the late 1930’s.
Cartography
Cartography is the study and practice of making maps. Combining science, aesthetics, and technique, cartography builds on the premise that reality can be modeled in ways that communicate spatial information effectively.The fundamental problems of traditional cartography are to:*Set the map's...

Map projection
A map projection is any method of representing the surface of a sphere or other three-dimensional body on a plane. Map projections are necessary for creating maps. All map projections distort the surface in some fashion...

Stereographic projection
The stereographic projection, in geometry, is a particular mapping that projects a sphere onto a plane. The projection is defined on the entire sphere, except at one point — the projection point. Where it is defined, the mapping is smooth and bijective. It is conformal, meaning that it...
