Description

This is a trivial variation of "Lambert Conic Conformal (1SP)" projection with only a sign changed. This is done by adjusting the appropriate coefficient in an affine transform matrix. The core of the map projection code is the same.

See §1.3.1.3 of IOGP Publication 373-7-2 – Geomatics Guidance Note number 7, part 2 – April 2015.
